Eruptions

Superfast entry as I run out the door but …

The new vent that opened on March 31 at Fimmvörðuhálsi in Iceland. The old vent is to the right in the image and new to the left. Image captured at 5:45PM EDT.

A second fissure has opened at the Fimmvörðuhálsi eruption in Iceland. Check out the webcam and you can clearly see a new set of vents (Icelandic – try Google Translate) on the left hand side of the image – and that wasn’t there earlier today. You can see an image of the new vents here.

Thank you to all the Eruptions readers who have been keeping us posted!

    Looks like it opened up parallel to the first. Tensional stress at work!

    Great views!

    Is there a map that shows where the fissure and cameras are located, along with N-S directions? I get turned around each time I look at these.

    @EKoh

    New rift is perpendicular to the old rift, but perhaps that’s what you meant.

    There is a chance of this new fissure to continue to expand, or there might even open up a 3rd fissure there soon. But it is bit uncertain what happens, as it appears that the crust is boiled in that area at the moment.

    where are you getting your info , do you have access to some tiltmeter data/dilation data, etc .. can you share the links (or repost them )

    @robert somerville, I don’t have anything like that. Even if I would like to. But I track the data that I can find on the internet. That is earthquakes, GPS, tremor plots etc. I do have my own seismometer (geophone). But it is located ~40 km away from the Eyjafjallajökull volcano and is having connection problems at the moment (internet issue it seems).

    The rest I do with really fancy calculations in my head. Even if I don’t understand normal maths like the one that they teach in school.

    This eruption is far for over…

    Let’s hope those fissures are not propagating towards Godabunga or Katla, that’s exactly what could trigger it.

    If escaping lava from Eyjafjallajökull injects trough the propagating fissures towards its neighbour, it could end up destabilizing what’s in Katla’s magma chamber and prime it for an eruption.

    Has anybody got a map of the vents?

  10. #10 EKoh
    March 31, 2010

    @3
    You’re right, its not parallel, I was eyeballing it from the photo. Based on the map you linked it looks like it could be a conjugate fissures (cross-cutting set which intersect at ~60° and ~120° angles), also possible with the tension and rifting going on. Its possible that instead of one fissure lengthening we could see an expanding set of fissures.

    The new fissure is almost in North-South line. While the older one is close to East-West.

    There is a risk of the new fissure expanding, or a new fissure opening up in the area. The eruption has not dropped in the old crater at all. It appears to be unaffected by this new fissure.

  14. #14 Jón Frímann
    March 31, 2010

    There appears to be a considerable risk that a new fissure is going to open under the glacier, and that means floods and explosive eruption in that area.

    Given the earthquakes 5km SSW of Básar there is a chance that a the new fissure is going to open there, or close to that area. This area is under glacier and that is just disaster waiting to happen if it starts quite like the other two fissures.

    This was meant to here. But did go in the other post by a mistake.

  15. #15 Chance Metz
    March 31, 2010

    You can clearly tell the second fissure is bigger. A lot more steam or ash is coming out of it and I belive I can see a cone already forming from all the lava and tephera.

    @Jon #14, I posted a message to yours on the other thread. I don’t do calculations in my head, but I get gut level feelings about things. When I saw the steaming this morning, I knew something was up.

  18. #19 Diane
    March 31, 2010

    Boy, I could be wrong, but between the origianl fissure and the new one there is a steam vent that seems to be getting more active at the moment. I am just wondering if it will also open up and I saw cars leaving that area last night!

  19. #20 robert somerville
    March 31, 2010

    the continuous GPS measurements last 2 days seem to indicate the area around the vents underwent/is undergoing significant inflation event, seems to be outside measurement error bars .. maybe this is going to get significantly bigger than first thought ???

    I have noticed that too. I would not be surpsied if it did open up. Of course it may mean that both fissures merge into one huge fissure. What does suprise me is how long the intnese activity has been going on. A few days ago it would wax and wane over time but for two days it has been going storng.

  21. #22 Jón Frímann
    March 31, 2010

    @Diane, you are correct. There is a steam vent there and it was not there around 19:00 to 00:30 UTC when the new fissure formed. This might well be a start of new fissure. But it hard to tell at the moment in the dark.

  22. #23 robert somerville
    March 31, 2010

    sorry if posting twice

    looking at the continous GPS, it appears that a significant inflation event has happened/is happening at the stations in the area (readings are outside error-bars, probably not all outliers in the same direction , looks like this thing is going/could be to be bigger than first thought :

    @Jon, actually I saw it a couple of nights ago when I was watching lava blocks fall on the back side of the mound. I figured it was that, but now it is much more promenant than it was. Now maybe what I was looking at was a car light, but I am not sure. It was odd to say the least. I hope it is just steam and gas from under some hot cinder or tephra. However, I think it is something more.

  24. #25 Gordys
    March 31, 2010

    Looks likes your new vent just went Diane. I wonder how much gas is in that magma. If this eruption coalesced into one large vent, would that be like taking the top off of a soda bottle?

  25. #26 Jón Frímann
    March 31, 2010

    @Diane, This area had a lot of steam activity before so that confused people. For instance the geologist and the news people did think that the steam from the new fissure was because of a lava flows in the area (according to the news earlier on Rúv). But that did change suddenly when the new fissure did start to open.

    The new fissure is currently creating a high level of steam activity. So much in fact you can hardly see the eruption from the Þórólfsfelli, web cam (Vodafone, Míla) and that is a lot of steam to block that view.

  26. #27 Diane
    March 31, 2010

    Gordys it hasn’t quite yet, but it is getting more active. I have seen three fingers of steam and gas from there.

    @Jon, you’re not kidding it is creating a lot of steam and gas! It looks like it is shooting up to about 1100 meters. At least the glow is that high or looks like it. I can see if there was gas and steam from the area before how it could confuse people. It just tells me to watch it for trouble. Sometimes a fumerol is just a fumerol and won’t do more than steam and gas away.

    Right now, it is just hard to take my eyes off of it!

  27. #28 Chance Metz
    March 31, 2010

    Why is the new fissure producing so much steam? intreraction with snow and lava prehaps.

  30. #31 George

    @Chance #28

    I would say it is probably interaction with ground water below the surface.

  31. #32 Chance Metz
    March 31, 2010

    Must be a lot of groundwater because by now you tihnk it would almsot all be vaporized.

  32. #33 George
    March 31, 2010

    @Chance #32

    There can sometimes be quite a bit of ground water and more seeping in as water is vaporized by the heat. Think of a shallow aquifer. As the water boils off, water from surrounding areas flows in. It would continue to steam like that until all the water is gone from the surrounding area and no more can seep into the hot spot.

  33. #34 Chance Metz
    March 31, 2010

    true and alot of that would be snow and ice melt so that makes sense.

    Watch the dark area between the two fissures, down at the base on either side. Signs of weakening and failure.

    The eruption is going to grow in strength.

  54. #55 Henrik
    April 1, 2010

    First of all, congratulations Jon! An e-Beer or a crate of it is most certainly indcated! It is very interesting to see which of the multitude of predictions over the last month or so that have turned out to be correct and the processes by which they were arrived at:

    The first prediction made was the area where the eruption would occur and it was made using “logical dedudtion”. This was made not on this blog but somewhere else in cyberspace and referred to here. IIRC, someone had had a look at the topographic map and spotted the old scoria cones in the Fimmvörðuhálsi area. If you look at pictures and maps of Eyjafjöllajökull, you will see that the base at approximately the 1000m a.s.l has several areas where previous eruptions have taken place. Since larger eruptions through the main vent would have buried these lesser sites, “logical deduction” would have provided the answer that this type of eruption has in geologically recent times been the most common and since the Fimmvörðuháls area is not glaciated, this area would be the most recent and thus likely area.

    The second prediction was as to the type of eruption by Bruce Stout and is an example of the “intuitive leap”. It sounds haphazard and chancy, but really isn’t. Bruce has great knowledge of volcanoes around the world and on a subconcious level, a comparison of known facts provided the answer.

    The third prediction was time, “just under a week” made five days before the eruption based on an analogy. This is an example of a genuinely “lucky guess” and not a true prediction even if thinking outside the box provided a seemingly correct answer.

    The fourth predition is Jón’s second vent, arrived at by logic deduction based on available facts. Incorporating all published data plus that of his own geophone/seismometer, Jón came to the conclusion that the eruption was not in decline and that in all likelihood, a second vent would open up. He based this (is this correct Jón?) on the following facts: a) there was no sustained deflation indicating that the eruption was not large enough to relieve the volcano of magma, b) seismicity continued at all levels which indicated one or more blocked passages which could yet open up, and c) harmonic tremor was sustained, even if variable. To his credit he stuck to his guns, even when faced by professional opposition, and was proven correct.

    While on the subject of predictions and guesses, may I draw your attention to a process known as “logic complementation”? We tend to see things that are not there but logic/experience tells us ought to be there, ie if we see smoke, logic and experience tell us there must be a fire somewhere close, thus we see it. This is very common in witness psychology but there have been several examples here, foremost of which is my own “observation” of new vents on the second or third morning of the eruption… :o

  55. #56 Jón Frímann
    April 1, 2010

    It is snow, the wind is in the direction from the eruption. But the local fog there appears to coming from the eruption.

  56. #57 Jón Frímann
    April 1, 2010

    @Henrik, I did notice that the earthquakes there where getting really shallow. Many of them where at ~100 meters. There is still a chance that there are going to open new fissures more to the north then before. But as things are changing it seems that a fissure opening under the glacier is the next thing to happen. There have been earthquakes in that area and they continue to get more shallow as more of them happen. They also carry the low period seismic signal, that tells me that magma is making the cracks wider in the crust. This simply might be a matter of time, or what is more likely is that there is a sudden increase inside Eyfjallajökull that starts that eruption with a bang. There might not be many earthquakes before that fissures opens up.

    The reason why we didn’t get any earthquake this time might because the crust here has turned “soft” because of the 1200C heat in the lava flows below it, from the feeder channel where the lava is pushing it self up.

    I use the method that can be simple explained like this. I check if there is a more possibly of B and D happening then C and A. It is a complex process. But it works most of the time. But not always as it goes.

  57. #58 Volcanophile

  58. #59 Volcanophile
    April 1, 2010

    I would like to say something about this current eruption.

    I’m sorry for my bad English as it is not my mother language, let’s hope I will manage to explain clearly what I mean…

    IMHO this eruption is not one from Eyjafjallajokull proper, but from a basaltic dike which coincidentally erupted in a location not too far from the preexisting volcano.

    Iceland is notorious for having lots of monogenic volcanic fissures, such things already happened around Hekla, where fissures nearby the main volcano erupted lava with an entirely different composition from the usual samples from Hekla itself.

    Only one thing could tell.. chemical analysis of the sample to know if the magma could relate to Eyjaf, to Katla or to something else (intruding basaltic dike, rifting event from elsewhere).

    But what’s not good is if there’s any silicic eruptible magma under Eyjaf or Katla, any basaltic melt going in the wrong place could start things off… indeed with a bang…

    Short but interesting report by a pilot who just spotted the moment when the second fissure opened. I´m envy that he could see this moment. He reports about a flash light and then suddenly the crack was open. I never saw this moment when a fissure opened so far, ther was just a webcam time-lapse fissure of the piton de la Fournaise. I did not know that it can go so fast, I thought there would be steam first, then maybe a little crack opening step by step. But it seem to open extremely fast. Read this on: http://www.icelandreview.com/icelandreview/daily_news/?cat_id=16567&ew_0_a_id=360266 People were making pictures shortly after it cracked – would love to see them….if anybody knows about a video or picture showing a fresh crack/ fissure, please let me know….

    Hi.

    I know nothing about volcanos and i am quite worried now.
    Could you guys please provide some sort of alert level so we ignorants have a chance to decide when its time to do something?
    Like when is it time to go buy food and so on.

    Also a little bit about possible scenarios would be very usefull.
    On many sites there are a lot of doomnuts talking about the end of the world etc. People like me need to lean on science and knowledge, so here i am!
    How serious can this be? Is it a possiblility of world wide impact at all?

    The steam plume is rising very high very fast by convection, and we can see it rotating counterclockwise.. something reminiscent of cumulonimbus clouds I believe..

    @gusan

    Buy food if you are hungry :)
    But seriously, this volcano is nowhere near the size of a catastrophe. The official size of this eruption is around VEI 1, which is the smallest, while Laki, Pinatubo or Krakatoa were classified as VEI 6, and they also not caused the end of the world, although were the largest eruptions within last millenium.
    This volcano is simply a bonsai among others, but is so well documented, measured, displayed, etc, that we love to look and talk about it.

  64. #65 Boris Behncke
    April 1, 2010

    Volcanophile certainly has a point, though from the seismic activity preceding the activity it seems to have come from below the center of Eyjafjallajökull, so it is probably closely related to that volcano. But it’s quite primitive basaltic magma, something that has not stayed and differentiated in a reservoir for some time. I am not very convinced there’s much risk of silicic magma being involved in this case, although it might turn out wishful thinking. In the ideal case this will continue to be one of these eruptions that play around opening a little fissure here and another there, like Hekla did in 1970. So I agree with Jón that more fissures will possibly open, though as things look for the moment, the largest risk remains that of snowmelt and phreatomagmatic explosions where there is interaction with snow. Much of the vapor and gas that we see in this moment is due to such interactions, and it appears much more voluminous because you can clearly see that the weather is more cloudy and humid. The Þórólfsfell actually shows a veil of cloud moving in, hiding the view of the eruption. Higher levels of relative air humidity lead to more condensation, a phenomenon everybody living near a constantly degassing volcano knows well, because on humid days gas emission appears more vigorous and voluminous although in reality there is no change in emission.

    I guess the lack of seismicity before the second fissure opened is because no new conduit has formed, the conduit has only bifurcated in its most superficial portion – it has propagated laterally. And again, our experience from Etna confirms that it’s not the opening of the fissures that makes seismic activity, it’s the vertical uprise of magma, and the breaking of rock in this process. When Etna erupted in 2001, the opening of the first fissures was preceded by four days of extremely strong seismic activity. During the next few days more fissures continued to open, over a whole length of about 6 km, but seismic activity died down after the first fissures opened.

    On the contrary, when there was long-lived activity that was fed by a sequence of little magma batches, you’d see seismic activity preceding each new batch by a few days. That’s exactly what has also happened here, and what led to Jón’s expectation of new vents opening. The question is, will this eruption evolve further, with still more vents opening? For once I hope Jón is not right when he says that the eruption might extend to the subglacial part of the volcano. That would render things more complicated and increase the hazard from this eruption, which is not what I wish people who live nearby.

    In the meantime a new map of the lava flows as of 31 March has been posted here:

    Well, this is bad. The expansion of THEY GPS station has started again. But that tells me that the volcano is inflating again, and that is bad is it fortelling of more fissures opening up in the area. There might not be a lot of vertical movement before a new fissure opens, but then it might. Hard to tell for sure.

    There has also been some earthquakes at ~5km SSW of Básar in the last few hours, and that is also a sign that new fissures might open up at any time with no warning at all. The earthquakes started to happen after the new fissure did open up.

    Wow! It is interesting with this new fissure opening. When I look at the fimmvörðuhálsi webcam I see some flames in a area halfway between the old cone and the large steam plume. Is this the new fissure? Or is the new fissure where all the steam is?

    Based on the Fimmvorduhals webcam, it appears to me that the steam/cloud arisen from the new fissure generated a local snowfall.

    Again, I would avoid catastrophisms, so far this is the most harmless type of eruption that there is, let’s simply enjoy it. I am sure Icelandic civil defense organisms stay put in case the scenario worsens, but for the moment there’s no way saying whether this will happen or not. What seems a good possibility is that the fissure system will expand further, like it did yesterday, but still all that we see so far is rather contained – a fissure system less than 1 km long, Hawaiian-style, nearly totally ash-free activity, this is even a small eruption for Iceland standards. We would absolutely looooooove to see such an eruption here on Etna (unless it happens close to populated area).

    And it is absolutely a very beautiful eruption. For those who haven’t yet realized this, look at this video, it’s breathtakingly spectacular.

    @Boris Behncke, I would like to avoid being with dangerous happening. However, I just use the data that I have and what they tell me. Currently the data is telling that there is a chance that there is going to open a fissure under the glacier. There are indicators that the current fissures are not enough to release the pressure that is building inside Eyjafjallajökull. That means that the magma is going to make a new path ways to release that pressure. The best way for the magma to do that is to go up in direct line. That line is under a small patch of glacier and now it is just a question of when, not if in my opinion.

    Harmonic tremors are on the increase in Eyjafjallajökull at the moment. It should show it self in the eruption soon or has already.

    Jón, we’re all watching … this is rather exciting. If a fissure really opens under the glacier you’ll have a bottle of real red wine from Etna. If it continues to open small fissures outside the glacier, you’ll have to content yourself with more e-beers :-)

    Volcanic lightning is not so crazy, Volcanophile. In fact it is a common phenomenon at volcanoes around the world. The frequent minor eruptions of Sakurajima and Krakatau often feature volcanic lightning in the plume. Perhaps it is unusual for a basaltic eruption though.

    @ Diane and Chance

    I just zoomedd the fimmvorduhalsi cam, and I agree, it looks like some steaming between the two current vents. The steaming seems to be in a fixed location. (Look at the second vent, and then go down to the right until halfway between the two vents. )

    My only experience with volcanos are those that are active (kiluea, shasta, pompeii, yellowstone) and there’s always breathing and huffing around them. This is the first “from nothing” volcano I’ve watched. Would gasses be leaking up with no eruptive consequences?

  84. #88 Randall Nix

    parclair some of that steaming is just steaming water vapor and not another vent opening. The lava flow is hitting ice or coming into contact with water.

    April 1, 2010

    Parclair, since they have moved the cam back, I can’t see what I was seeing last night which was some steaming between the two vents. I suspect it can open up if it is more than just steam from water vapor as Randall has said. Before the second fissure opened up I saw a lot of steaming in that area and I thought something was up and it sure was up! I am not sure if that area will do anything more than just steam.

    Have you climbed Lassen? I have been on top twice and I just wish I could have had time and energy to take a look around. I would love to climb it again, but that is out of the question.

  87. #91 George

    “Parclair, since they have moved the cam back”

  88. #92 Chris
    April 1, 2010

    The area were the second fissure opened was covered with snow from the winter. No wonder that there is a lot of steam.
    Its the same with the “old” fissure, the lava thawed the snow, which was there. Its quite a strange image, red glowing lava next to snow.

  89. #93 Diane

    Parclair, you know what?! I just took a good look at the cam again and I think that little steam area I saw last night just might have opened up. The stuff coming from it looks black so maybe it did crack open. Not sure, but it does look like it. Steam is usually NOT black!

    The earthquake at 15:07 UTC was a low frequency earthquake (ML2.9 0km event), that means that magma created it and the magma is now at ~0km depth and is cooking the rock at the moment. But it does not appear that it has pushed trough the crust yet. Even if it at shallow depth. The harmonic tremors are increasing according to IMO plots. This is developing really dangerous way. It is hard to tell when the magma might break up. But that is only when the pressure is enough on it, and that does not appears to have happened yet.

    Are the Vodaphone and Fimmvörðuhálsi webcam image fields opposite of one another?

    On the Fimmvörðuhálsi (site linked in Eriks opener to this thread) camera, to which fissure vent does the far-right, nearly off-camera plume belong?

    To me, it looks like a new emission source, but you I can’t be sure because of the shift in perspective with this camera since last night.

    The camera image field change: although whether physically moved or by camera focal zoom is uncertain, except that there are tell-tale tracks that suggest it may have been physically relocated for equipment safety or to expand the visual field.

    Interesting to note the diurnal shifts in activity.

    Passerby, I determine the cam views by the plume drift. Right now, it appears that all plumes are drifting to the right, so I’m assuming both fimmvorduhalsi and the vodaphone cams are pointing in the same direction from the same general area.

    Boy, the snow field on the fimmvorduhalsi cam is getting dirty. There’s some grey on the right foreground that could be evidence of a ‘dirty’ vent on the right, off camera. (Earlier the plumes were drifting more to the left, which is when I saw the plume coming from the right of the camera.

    I’m going to be offline for a few hours, and miss the sunset. Can someone do some screen grabs from the fimmvorduhalsi cam? I think I’ll be able to get eldgos on my droid (if I can figure out how to refresh). Thanks much.

    @passerby, with huge billowing clouds of steam and molten rocks being ejected hundreds of feet into the air, doesn’t a sign saying “don’t go past this point” seem a bit redundant?

    I remember when St Helens was getting close to its big blow, and the local authorities were trying to get people off the mountain, with a common response being “I’m not going to let the g’vment tell me where I can go and where I can’t go.

    Morgunblaðið has just released a short interview with one of Iceland’s foremost volcanologists, Magnús Tumi Guðmundsson. He described the eruption as “stable” and said there was no way predicting how long it would last. The opening of the new fissure yesterday (31 March) was in his opinion due to magma finding a path through fractured and weakened rock. Asked about the significance of earthquakes below Eyjafjallajökull today, he said there was nothing special about them, that there had been a lot of seismicity since the start of the eruption, and this was caused by the continued ascent of magma.

    This interview plus another impressive video can be found at the following link:
    http://mbl.is/mm/frettir/innlent/2010/04/01/mallar_afram_naestu_vikurnar/

    From this video and another one that I indicated in comment #72, you can appreciate how much the lava has already filled of the deep canyon into which it is continuing to cascade.

    Watching the closest webcam in the late afternoon light, there is nothing I can relate to further vents opening, it does indeed seem stable. Lava emission seems to be pulsating, which is why there are repeatedly new surges advancing in direcions previously spared by lava flows. The new flows thus encounter remaining snow, each time producing a lot of large steam plumes.

    People are ignoring the ban of travel to this area. The own risk zone is 5 km around the eruption area, the ban zone is 1km around the around the eruption.

    For example, imagine I held a stick that I had removed from a fire. In daylight the end would look black. But in darkness you would be able to see the glowing ember that is not visible in daylight. It is sort of the same thing going on here. That and the illumination of steam from the eruption which makes it very difficult to tell at night which is the vent and which is steam with a webcam while you can clearly see the difference in daylight.

    The lava that is pushing up appears to reach the hight of 200 to 300 meters easy. The camera is located a bit far away, as you can see by the size of the cars.

    The camera view has changed since that picture was taken. The view is “zoomed out” to give a wider field of view than it had 24 hours ago. You can now see more stuff to the left that was invisible to the camera last night. (Talking about the view frá Fimmvörðuhálsi) It might be slightly more active, and you are going to see more from the opposite side (the view frá Þórólfsfelli) because the lava field has grown considerably in the last 24 hours.

    Overall, it looks to me like the eruption is relatively stable. And it could stay like this for a year or stop next week or get twice as big tomorrow. We just can’t tell.

Of course there were those EQs earlier today, do we have magma finding other places to go that have not shown up yet? What is going to happen tomorrow? What is the supply system? We don’t know.

    I’ve got my 2 cents of quite unscientific thought…

    Basically, besides differences in lava chemistry, gas contents etc, eruptions come in 2 styles…

    There are the ones which start big and calm down progressively, such as Chaitén, Hekla, etc… Typically the most silica and gas rich magma comes up explosively in the first place, and, as the gas supply is more and more depleted, the eruptions become weaker and weaker, more and more effusive or extrusive.

    And there is te other kind… When things start slow, gently, then ramp up and up to the final pyrotechnics. Something like Tungurahua, Mayon, Vesuvius 1906.. In those eruptions, the more magma is erupted, the more hotter, gas-richer magma comes up and makes an even larger way for more, even hotter, even gassier magma to come.

    We don’t have a clue about what Eyjaf is going to do next… Wait and see… but, it indeed seems gearing up now..

  161. #165 Gordys
    April 1, 2010

    Randall, lets think about this now. Just getting to this point was iffy, there have been intrusions before and nothing has happened. I am thinking with just the eruption starting, you have used up an ace, king and a pair of jacks. With the new fissure yesterday, you used up a couple of queens. So what I am thinking so far, you have used up an ace, king, two queens and a pair of jacks. We have to think about what altitude this eruption is going on at. I’ll bet you one of my aces and one of my kings that the next fissure opens up at a lower elevation that what the eruption is at now….unless we get a new magma influx, maybe for some reason the plumbing to the current eruption site gets blocked, or the throat that the eruption is keeping all of us so mesmerized gets blocked…then??

  162. #166 Volcanophile
    April 1, 2010

    Sometimes basaltic fissures eruptions can and do become much more explosive…

    For example, this is a basaltic fissure eruption in Mihara Yama, in Japan, 1986…

    http://hakone.eri.u-tokyo.ac.jp/kazan/gif/O86.2.JPEG

    And another one… just for fun… not too far from us in Europe, Boris will certainly recognize it …

    http://www.decadevolcano.net/photos/etna1002/etna_28732.jpg

    If the magma feeding Eyjaf’s eruption becomes more gas-rich, or if the next fracture meets a shallow aquifer (whigh would create steam, and herefore gas pressure), things could start to get much more interesting…

  163. #167 Randall Nix
    April 1, 2010

    Gordys these two fissures are small face cards at most;) I am with you though I bet the next one does come lower down.

  164. #168 Henrik
    April 1, 2010

    Gordys, Randall! The the two fissures are about 4-5 km from the main conduit/feed from below (~5 km SSW Básar). Right now, the last bit of ground above is too hard to break through and the magma has found a path of lesser resistance, more or less horizontal, to the fissures. My bet is that IF the magma breaks through in another place, it will be much closer to the main conduit. We’ve already had a M 2.9 at 0.0 m depth, which Jón says had a magmatic signature, about 1½ km north or NNE of the main conduit. If you are on PayPal, what about a real bottle of red on that?

    About people taking unacceptable risks – note that hardly (if any, as it’s an large area, unaccessable w/o guide) any tourist will go on his own. It are the tour-operators that take the risks. As a tourist, you rely on the tour-operator, and as usual – it’s all about money. Last night, saw tremendous amounts of headlights on the webcam – either snowmobiles or 4wd’s. Big money for the Icelandic tourist-industry, on average 400 Euro’s or so, and tourists have to sign they accept the risk. If you go to Iceland for the eruption only, and the operator tells you it’s save (“we know the location situation, and we take safety first”), what would you do as a tourist ?

    If you want a good “explosive” basaltic fissure eruption, try the Tarawera 1886 eruption. It had no flows and a fire fountain that supposedly reached 3000 meters! A “basaltic plinian” eruption.

    When it comes to volcanoes everyone is a tourist. Consider all the volcanologists who have died in various eruptions in recent decades – at Semeru, Galeras, Unzen…..What constitutes “unacceptable risks”? Unacceptable to whom? As long as people are aware/informed of the dangers then they should be free to make their own decisions as to how much risk they take. In this case, the risk seems pretty minimal and I would go there right now if I could. Who here wouldn’t?

    Fireman, that is what I suspected. At one point, it looked very much like a vehicle had driven right to the active edge of the largest vent, and when the eruption suddenly flared up, the jeep disappeared into the glare. When the flare died down, it looked like the vehicle might be burning, as it was conspicuously bright. But you just couldn’t be sure of how close the many jeeps and snowmobiles were to the vents.

    Still unsure of the cause of the occasional narrow ribbons – brief light flares in the webcam nearfield. Didn’t look like image distortion, but might be a transmission artifact.

    The harmonic tremors where just taking a big jump few moments ago it seems. That cannot mean anything good in my opinion. But I hope that for now the current fissures can keep up with the inflow of magma into Eyjafjallajökull.

    Passerby, if you’re talking about twin streaks coming off the hill mid-screen on the frimmvorduhalis cam, I’m pretty sure those are vehicles of some kind. I’ve seen them the last couple of nights, and there’s a distinct pooling-of-light effect as they come down the hill to the flat area.

    Parclair, re Lassen: It was quite a long time ago I climbed it, too, as in 30 years! I remember looking down at the parking lot when I was about half way up and I saw some kids start up the trail. When I had gone about another half mile, they had caught up with me! Real good feeling. LOL It was really neat up there. I could not do it today.

    I think they needed to post safe places to go and see the eruption. I know people do get too close. Even volcanologists risk their lives to get the info from the lava flows and all the other stuff that comes out of them. I have seen a picture of John Seach dressed in silver heat protective clothing almost at the edge of an erupting basaltic volcano. They do take precausions, but sometimes it gets them. I just hope nobody gets hurt in Iceland and everybody that goes to it has a good time.

  187. #192 Diane

    Gina, I’m not sure, but on the one site, one is disconnected and you can’t see anything on the other.

    How about it? Are any of them working where you can see something?

  188. @Thomas Wipf 60 and others – a note here about speed. The important point I would like to make is that at a time of low seismicity, there were 3 straight-shot vertical bursts of magma, one on top of the other (practically). The first burst opened the new fissure and was traveling at great speed. Here’s my evaluation:

    Seven nearly simultaneous quakes starting at 15:07 UT/11:07 AM EDT.

    Set One traveled vertically 2.4 kilometres in 17 seconds (its 2nd and final expansion of the set – at surface/0 km. ripped it open like a zipper) and was the most forceful – R2.8

    …50 seconds delay, then…
    Set Two traveled vertically 2.2 kilometres in 14 seconds (its 2nd and final expansion of the set – at the 1.4 km. depth)

    …70 seconds delay, then…
    Set Three traveled vertically 2.7 kilometres in 13 min 17 sec. (its 3rd and final expansion of the set – at 1.3 km depth)

    So as I “see” it (since all three ejections vertically smoothed the walls, subsequently there has been little seismicity because there has been little resistance. In addition, since set 2 and set 3 each expanded the “walls” at the 1.3km depth, there is a wider “throat” there into which to pump more magma. So this one could be a “keeper” and the one higher on Fimmvörðuháls may gradually block up.

    I think it’s important, however, to consider that if there is more vertical deformation that even this significant a fissure is not relieving the upward pressure from the reservoir which wants release. And this magma can travel quickly and without warning when it wants to get “out”… 2.2 kilometres in 14 seconds equals about 155 metres per second… again, I remind, without prior warning! Despite the wise words of a senior geologist, nobody *really* knew it was going to come out there.

    Everyone think about this please. If there is more vertical deformation I suggest that Civic Protection remove people from Eyjaföll altogether. This is not some dolphin show.

    And I also remind folks that the pattern of consistent and early “channel-opening”… secondarily most prominent (after the present fissure location)… was under the southeast flank facing the sea – not under Gigajökull. Magma already opened its advance path within Eyjafjallajökull, inside the mountain and almost all the way down to the sea… view Socuel’s timelapse again if you’ve forgotten.

    p.s. the uppermost panorama (click on my name-link) shows both gorges, I believe, down which magma and lahars are now flowing. The hiking trail is between them.

    April 2, 2010

    @ Jón regarding the chance of a fissure opening up under the main focus of seismic activity and the 4km lateral branching of the conduit very near the service to the eruption site:

    What I imagine is that the main conduit rises up the main EW fault line underneath Eyjafjallajökull until near the surface where there is a sudden discontinuity in the fault line, possibly because it is capped with a “recent” lava flow that hasn’t faulted yet. The magma then flows sideways along the fault line and underneath this cap until it reaches the edge where it erupts.
    The alignment of the surface fissures still intrigues me though. I can only think this is some kind of surface anomaly.
    As for a sub-glacial eruption, we probably won’t see one until a weakness develops in the overlying cap for the magma to exploit. This would probably equate with the larger earthquake that you were waiting for. Alternatively, the magma might find some other weakness in the overlying rock but this is a big unknown. I’d love to know what is happening to the west of the diversion!! I assume this avenue is plugged otherwise we would have seen some kind of activity there (melt sinks in the glacier, etc). Do you know if, and how, this is being monitored? This might be an issue, particularly if inflation resumed. (on this note, do you know why the GPS plots a week old? They weren’t always like that!)

    At the moment though, I would put my money on the activity staying in the region where it is.

    I also see the “snake eyes’ in the screen. During the day, I mentioned them, and someone (can’t remember who, sorry) thought they were steam eruptions from lava flow. I’m not sure, because from the distant webcam, I think they’d be uphill from the 2nd outbreak. (Trying to keep things in spatial place is hard with only pictures). I’m watching them too.

  209. #214 Jón Frímann
    April 2, 2010

    @bruce stout, the earthquake that I was waiting has possibly already happened(?). It was a ML3.1 earthquake that did happen in the early progress when this all started. The activity might continue in that area, but that area also has glacier. This thin glacier free patch is not big and any more fissure are might end up under the glacier at any time.

    @parclair, I am going to sleep now. But this days I sleep in 5 to 6 hours at each time, and when there is a break or things get stable with the eruption. I sleep a lot. I don’t have a job, so it is ok.

  210. #215 bruce stout
    April 2, 2010

    @ Jon, ha! another night owl! I also often get by on very little sleep. Far too much happening to waste it in bed!

    Re the fissures spreading uphill towards the glacier. If the above reasoning is correct (i.e. a cap sitting on the main fault line, then the fissures are not likely to propagate uphill unless the cap is particularly thin and weak. They might propagate downhill though, at least until the elevation of the main lateral conduit. If this height is anyway where the eruption is, then activity will stay where it is, probably with more fissures opening up near to the existing ones.

    @Randall Nix, it was a normal earthquake. But closer to the surface then normal. It is also located outside all known volcano areas far as I can tell. Even if it was close to Mýrdalsjökull volcano, it appears outside it.

    This just the local bedrock stretching it self and adjusting. But for what is the good question, I might not like the answer to that given the clues that I am getting.

    The harmonic tremors are on the increase now for some reason.

    The recent spike in tremors might be due to weather-induced noise (wind, snow, rain, etc) occurring near the seismometer(s).

    Randall, Jón! If you look at the radar map showing inflation from space, you’ll see that this EQ was right at the edge of the “inflation zone”.

    Well, there seems to be a white-out on one of the cams and the other one sure shows a lot of snow with the wind blowing a gale.

    I checked the cam before all that started and the area where people were driving over seemed black. It is turning back to white now. Did something happen last night that caused more ash to be flying around?

    @Randall, I dig your quotes from Shakespeare even if I am not a fan of the old bard. He’s ok, just not my cup of tea. :-) If I do any reading at all it would be a biography or something related to geology and volcanology. I used to do a lot of reading. I’m one of those who never quite figured out what I wanted to do. Spent 16yrs in college for two degrees and got burned out. Was going for my MA when I quit. Too much arglebargle. ;-}

    hmmm … snow and fog at the volcano, nothing to see this afternoon, though all your contributions, especially the excursions into literture and drama here are certainly enlightening! But if you want to see some gorgeous images of the Eyjafjallajökull-Fimmvörðuháls eruption, I recommend that you re-check Flickr:

    @Gina, I bet it is! From what I was able to see on the cam it was blowing sideways alright. The closest I came to that was in ’91 when we had one heck of a blizzard here with 40-50knot winds and at my place I got 30″ of snow in one day at 2700′ in the Sierras! They got about 4′ in town at 3200′. One guy who had lived here since ’45 had not seen snow like that. So far, we have had 23″ (since Dec. when we had 14″) where I live now, just about a mile from where I used to live and now I am at about 2500′. Had 2″ on Wed. and by the end of the day it was gone. It could snow again tonight if the temp goes down.

    @george #249,

    the scoria is very black. So the surface cools quickly by radiation to the clear artic skies and by conduction to the cold icelandic wind. But since it is also very porous it is a good thermal insulator. The cone will be very hot just a few inches below the surface even though snow can stick to the surface. Also, since snow is in itself a good thermal insulator, it helps the cone maintain its internal temperature. Without a penetrating rain, the cone will stay warm for quite a while.

    According to the news tonight (that I have look better at). It appears that the magma is coming straight from the mantle and from a great depth. It does not appear to stop in a magma chamber at all it seems.

    It is getting dark so as usual, you can now see more than you can during the day. It looks like it “intensifies” every evening.

    Anyway, the tremor seems to be picking up so maybe it is really increasing in output.

  260. #265 Randall Nix

  262. #267 George
    April 2, 2010

    I also note that the Þórólfsfelli camera has been “zoomed in” since yesterday’s view so the lava field and vent(s) are going to take up more if the field of view.

  263. #268 Gina

    Coming staight from the mantle.
    would not be a real surprise.
    We were talking about it since those “organised spikes”
    I think this wil get Peter’s attention to.

    @Jón did they say how the know it’s coming straight from te mantle?

  265. #270 Henrik
    April 2, 2010

    That’s a very interesting piece of information Jón! This would mean that the magma that made the breach – 6 cm over an area of 20+km diameter ~0.02 cu km – is just sitting there, filling up most fissures underneath Eyjafjöllajökull. When the deep eruption is over, you’ll have a mountain that is 6 cm higher with the old fissures sealed by tough basalt. This is probably an explanation why there was such a pronounced eq activity before the eruption – old, basaltic eruptions behaving similarly.

    (PS. Philosophy is logic unbridled by science…)

  266. #271 George
    April 2, 2010

    Well, maybe they didn’t zoom that camera in after all. It looks like just the snow cover changing the look of the topology to cover some “landmarks” I was using to judge things and that the lava flow has continued to expand.

    Maybe it hasn’t been zoomed in, I can’t be positive either way until some of that snow melts.

  267. #272 Gina
    April 2, 2010

    my eyes might be deceiving me but it looks like a new fissure is opening a bit closer to the camera 2 very hot spots on the left and the right side flow is also getting hotter

  268. #273 Gordys
    April 2, 2010

    Randall, I don’t read Icelandic either, I can get an idea of what is being said in Spanish and French but that is it. Google’s web browser “Chrome” does a good job. Sometimes very interesting in Icelandic but it makes a huge difference. I have not yet figured out how to get it to translate .pdf or .jpg files, I don’t think that it can yet.

  271. #276 Jón Frímann
    April 2, 2010

    @Frankill, I think they know by chemical analyse the lava and the ash.

    @Henrik, actually. That means that the magma that was before this began in 1994 has been remelted to a point, and most of it might already have erupted since the eruption did start. But there is a lot of old and new magma mix down there that appears to be ready to find its way up sooner rather then later.

  272. #277 Gordys
    April 2, 2010

    @Henrik,
    That 5 Km long horizontal long conduit to the eruption site..lots of pressure….hmmm. I hate to say it. but I don’t think that I would like to be on one of the snowmobiles that I see in the camera.

    @Randall, check comment 168. We may both owe Henrik a bottle of real wine. If it happens I promise that I’ll go in on my half…hope it doesn’t though. An eruption under the glacier would cause more than just a mess.

    Hope for the best, prepare for the worst.

  275. #280 Randall Nix
    April 2, 2010

    Gordys I think I misunderstood you up there and thought you said Jon but if it does what Henrik says then I will go an inexpensive bottle;) Or I could mail him one of my good ones say a vintage Bordeaux (IF?) I can get it shipped to him….But if the vent opens below the others he doesn’t win….right? He is saying “more or less horizontal, to the fissures. IF the magma breaks through in another place, it will be much closer to the main conduit”

    @Gordys, Randall: I think the time axis at the GPS pages (http://hraun.vedur.is/ja/gps/predorb/theypred.html) are in decimal parts of a year. Today is the 92nd day, 92/365 is just over 0.25, hence 2010.25 for the last tick mark.

    Right now, nothing points to the eruption getting bigger or a new vent opening, in fact it seems to be dying down. But if there is a new twist and a new vent does open where Jón and I think, I’ll settle for an e-Brand at the moment provided there’s an option on a real one to be shared between us at a later date. Hopefully most of us can get together for the little excursion to the Eifel area that was discussed a few weeks back.

    @Randall Nix, I live about ~150 km away from the volcano. But I can still get ash falls over me if that starts. The data from the automatic system, and the quality is rather poor it seems.

    April 2, 2010

    Cams have all been useless for me in the USA (yes, arrived home earlier this evening!) for the last hour or two at least. Vodaphone shows archives from earlier today. but nothing recent or live. Hekla is ‘buffering’ but never manages to display anything, Þórólfsfelli worked earlier, is now black, Fimmvörðuhálsi is ‘disconnected’, the simnet Eyjafjallajökull cam is showing (apparently live) darkness with nothing visible.

  310. #316 Jón Frímann
    April 2, 2010

    @parclair, that should not happen. I did send a email to Vodafone complaining about this issue. Hopefully they fix this after Easter.

    I don’t have any supplies, besides the normal that I keep. I won’t do any such arrangement unless I need to.

    The eruption is going strong it seems, with no signs of even slowing down.

    @Randall Nix, Katla is going to start erupting at one day. The question is just when. But the eruption in Katla can be be over in a week or two. But they can also last for one year at the longest.

    @Fireman, the web cam that I point to is at distance of ~45km. That is why you don’t see anything.

    Well now, things could get interesting. We’ve got a large coronal hole sliding into view, beaming a strong solar wind stream that will cause geomagnetic effects at high latitudes over the next several days.

    Looking at the USGS 7-day Global EQ Map, the number has moved smartly upward, with several interesting ones, including the only hotspot north of Iceland, Jan Mayen Island that also sits on the Mid Atlantic Ridge (MAR). At it’s height of recent activity in March just before our Eyjaf erupted, we saw an average of 260 on the map; it’s dropped down as low as 155 in the past week, but its now up at 191, including an EQ in central Turkey and Poland.

    @Passerby, the Vodafone web cam loses focus in the dark. I don’t know why. But it has something to do with the software that they are using.

    It has focus too much it seems. It will get better when the daylight starts.

    It is now just 1.5 month until there is 24 hour daylight in Iceland.

    Dasnowskier #286 :-)! To your #287, I do understand what you mean but, should we really give up our cultural heritage because it offends some simpleton who cannot place it in the correct context? Isn’t it fair to say that when we encounter something we do not understand, we should not destroy the evidence of our ignorance but rather make an effort to understand it? If the former, it will not be long before we have returned to pig-ignorance and witches will yet again be burnt which is the last thing we want. This is what history teaches us and, as was pointed out a few weeks ago, if we ignore the lessons of history we are doomed to repeat it…

    Diane, your #292 is pretty good! I take it it’s the first in a series of twinned couplets dedicated to the world’s volcanoes?

    Randall, me neither. The only way to combat ignorance and the intolerance it breeds is through education. When ignorance rears its ugly head and claims education and knowledge are offensive, I draw the line. When good people such as Dasnowskier feel they have to retract perfectly legitimate statements and quotes out of fear that some ignorant fool somewhere might find it “offensive”, the line has been well and truly crossed.

    Thank you Jón, that is a very interesting result, not only for vulcanologists but also for rock hounds such as the sapphirophile Randall and my garnetophile self!

    Randall, IF there are pockets of pegmatite on that mountain where gems might have formed, the amount of Ti in relation to Fe (in a different environment, we might get the required Ti2O3 and Fe2O3) tells me that there is a goodly chance of grayish blue sapphire, possibly of the star variety given the prevalence of titanium (rutile needles, ie the TiO2 reported). Katla would thus be a better bet for decent-to-good blue. ;) When it comes to garnets, the most likely ones would be almandite, pyrope and grossularite with their intermediaries. But there would also be a chance to find the very rare titanium andradites. No chrome or vanadium, so I expect no bright colours in the garnets.

    IF, a big IF the right conditions exist/have existed. Again, thanks Jón for the link!

    No way. Fáfnir is the name of an Icelandic motorcycle club, a Hells Angels associate that’s only a few steps away from becoming a fully qualified member.

    As for a name for the new volcano there have been several suggestions. The one I like the best is “Kettlingur” (Kitten).

    The harmonic tremor in Eyjafjallajökull is increasing at this moment. It does not appear to be related to steam explosion. But that was a theory put forward in the news today by geologist.

    I guess this means that the flow is increasing, and that also means that there is a risk for new fissures opening at any time.

    Otherwise the eruption is stable and does not even appear to close to being over.

    I wonder if this is like in the year 1612 eruption, or in the year 912 eruption. Sadly, there are few reports on the later one and none on the 912 one.

    @346 (Jón Frímann): do you know if raw seismic data from seismometers installed near the erupting volcano are publicly available somewhere for downloading? By analyzing them, it would be possible to tell if the recent increase in tremors we are seeing is really due to volcanic/harmonic tremors or, instead, mostly due to noise induced by the currently bad weather.

  347. #353 Boris Behncke
    April 3, 2010

    This one’s off-topic as well, but it might be a forerunner for a new thread here at “Eruptions”.

    Our volcano here, Etna, seems to be a bit jealous of the massive interest in the Eyjafjallajökull-Fimmvörðuháls show. Following a cluster of small seismic swarms during the past week, a more serious seismic sequence was recorded on Etna’s northeast flank last night, starting with a M4.2 eartquake at 20.04 GMT. That event occurred at the Pernicana Fault, which is an old acquaintance for us – it’s the most active fault of a dozen on Etna, and it plays a fundamental role in its dynamics.

    The hypocenter of that earthquake was very shallow – about 1 km. That is typical of Pernicana earthquakes, because this fault shows mostly horizontal movement, and it cuts to a depth of maybe 6-8 km below the surface, it’s a fault that borders a mobile portion of Etna’s flank, which shows conspicuous movement eastward, toward the Ionian Sea. Each time this sector moves, we see displacement and often ground rupturing at the Pernicana fault. Ground fracturing was last seen in June 2004, and now again, during the night of 2-3 April 2010.

    I’ve posted a series of photos taken today during a field survey in the area affected by ground fracturing at Flickr: http://www.flickr.com/photos/etnaboris/sets/72157623637273651/

    We know that the displacement of Etna’s east flank, of which the earthquakes at the Pernicana are usually a first indicator, is often followed by flank eruptions. So it was in 1981, in 1984-1985, in 1986, in 2002, and in 2004. The interval between Pernicana ruptures and flank eruptions has varied from a few hours to several months. So chances are that Etna will erupt again in the near future – not tomorrow it seems, but within a few weeks to months.

    Enough space and material for speculation, bets, and discussion here! And if Etna erupts before, say, June 2010, one E-beer (plus a number of real ones) is certainly for me.

A talent such as yours sir, is wasted on field work when the world ought to be your classroom. I am a professional educator. I have taught pedagogy to aspiring teachers at uni. I hope I do not embarrass you, but in you I recognise the virtues of the first-class teacher.

    @Henrik #354, I agree with you whole heartedly! I have know Boris for quite some time and he defininely is a teacher in the best sense. I don’t think his time as a field volcanologist is wasted at all. I think sometimes the field geologists/volcanologists actually know more about it than the ones who just study the subject without actually seeing what they are studying. I think all geologists and volcanologists need to get out in the field at least once in a while.

    @Boris, seems like that road always gets cracks when there is even a mild (by our standards here in CA) quake. I guess it was the series that kept the cracks coming.

    Thanks for the heads up on Etna. I just want to let you know something. Your site where you posted updates and such was the first one I found and I have appreciated all the info you were so willing to share with me since before you got your PhD! I hope you are not embarrassed because you don’t need to be. We are greatful for your input. I know I am. So many ebeers to you.

    Etna shares interesting tectonic and magmetic similarities to EVZ volcanoes. Grimsvotn also erupted in 2004 and coincided with heightened seismic activity at Katla.

    Boris, it’s possible that Etna will erupt, maybe for the same reasons as we are seeing rare eruption of Eyjaf.

    Etna also has a magnetic personality.

  354. #360 Boris Behncke
    April 3, 2010

    Why, thanks folks. That’s not embarrassing, your appreciation, it’s a great pleasure. It makes me feel that my message has gone through. Thanks to you all for the intellectual input, the interest, and the passion, and for all the hints at information that no one of us would have found on her or his own as completely as it came across this blog.

    I’ve done many years of teaching, both at local schools in the Etna area and also for American students in the Study Abroad program and at the Mediterranean Center for Arts and Sciences in Siracusa, 80 km south of Etna. Communication with non-experts is, in my opinion, paramount in our job, although this is not yet universally understood and applied, and in Italy it’s a bit more difficult still. Unfortunately here we have a government that doesn’t give a **** for education in all senses. But that’s another story. Fact is, I do love to share what little I hope I have learned and understood. And here we have one of the most amazing volcanoes to tell the world of.

    Field work is the flesh and blood of geology, so without it I would feel deprived of one of the most refreshing and exciting aspects of my work. Driving up the mountain to see the effects of the Pernicana earthquakes today was one of those experiences where you feel your tension and expectation mount, because all I had heard was that there had been ground fracturing but I didn’t know the extent of it. When I saw it, I just went “holy ****” repeatedly (rather the Sicilian version of it). But I do love the teaching and communicating as much as the work in the field, and having all together plus the principal work at the INGV, well … I could imagine my life easily having gone in a much more bland way than this.

    Diane, it’s good to be back in touch. You witnessed, at a distance of thousands of miles, one of the most extraordinary periods of activity our volcano has had since humans observe it – back in 2000 Etna broke a number of world records. We over here all hope it will one day do something similar again, in 2006-2007 it did a little bit of it but not on the scale as at the turn of the millennium. Now you’re there from the start as Etna prepares for its next eruption, which will probably be something new because that big lady always does something new.

    We just hope that it will not be too much of a mess. The likelihood that Etna’s next eruption will be far more dangerous than the current one in Iceland is elevated. Already the earthquakes of this night have caused more damage than Eyjafjallajökull-Fimmvörðuháls …

  355. #361 Henrik
    April 3, 2010

    May I turn your attention north, to the Tjörnes Fracture Zone, ~15 km WSW/SSW Kopasker where there’s been sustained EQ activity at a location offshore? It’s just had two M 2.1 and one 1.7 at 22.4, 9.8 and 5.9 km in a manner reminiscent of the ones that have heralded increases in the Eyjafjöll eruption and also the new fissure opening.

Certainly there is some of that, but there’s also tons of politics. I don’t object to the politics, it’s just not what I was hoping to find. This discussion is exactly what I imagined and hoped to find. Theories discussed in a civil manner; wonder, amazement and beauty shared; and even poetry!

    Could it have something to do with the fact that it gave a very good view, not only of the eruption, but also of the extent to which entrepreneurs circumvent the prohibitions laid down in order to reap the full reward of this windfall?

    @Boris, I remember watching Etna’s SE crater spew Stombolian style when the web cam changed every 30 seconds. I have watched it grow larger over the years and it has been really a neat thing to see. When they changed the cam I have had nothing but trouble getting to it and you told me it was because of politics that it was changed in the first place. Oh well, things change all the time.

    It was before my DH and I got married that we had the opportunity to watch Etna from Etna Treking when it was really going to town and flowing big time into Vale de Bove. We couldn’t take our eyes off of it and then Treking went off line. I emailed you about that and you said it had something to do with the outfit that was sponsoring the cams. Same group that did it for who you work for. Politics again. On that note, we are not happy with the *&%$&^%(*& we have in office now. That is all I am going to say about that.

    Back to Etna. I will be watching and waiting to see what the evious lady will do. You never know.

    @Jon, I think something is happening, but I don’t see a red dot, but that might have been where it is fountaining more to the left of the main (largest) fountain I see. I can barely make out some steaming and a bit of glow (very hard to see) to the left and futher down the pike. I think it is what is going into the canyon. Keep us up on what you think.

  376. #382 Viktor

    I could swear it was a new fissure with steam explosion, appr. 500 meters east from the original vents. It went on for 2-3 minutes, then finished.

  377. #383 Diane

    Jon, I have seen a lot of lights go on and off and I think some of the dots of light are tourists out there getting to places they maybe shouldn’t be. I saw a very bright light to the left and up rather high so that maybe was a copter.

    @Fireman (#370). Not in real-time, which would allow – or even make – law-enforcement officials act when too many people + vehicles congregate dangerously close. Sadly, only 1/6 will never do anything they know is illegal or wrong even if there’s no chance of being caught. 4/6 will never do anything they know is illegal or wrong – if there’s a chance of being caught, otherwise they will if the temptation is big enough. The last 1/6 will do whatever they please and d–n the risk of being caught. That’s the general human population for you, but I’d willingly give you 99% law-abiding people if you give me the possibility of at least one rascal.

    Unfortunately, it is not far-fetched that such a rapscallion, intent on making as much money as possible, would react to police instructions that would mean a decline in income (“If you don’t respect these instructions, we have to regulate traffic”) would remove the one source of real-time information.

    Now, if there is an official presense at the vent 24/7, I would have to concede that it’s not longer a plausible explanation!

    The bright spot east of the original fissure is getting brighter, it does not look like it is a lava flow. The area is close to the upper left corner of the image from Vodafone.

    It might well be that the steam explosion was because of the lava. That is why I was seeking conformation on that event.

    @Henrik – I should have mentioned that: both nights I was up there, there were mountain rescue and police on-site. If they wanted to warn people off, all they had to do was tell them – or make a couple of arrests, if they really wanted to make a point. They didn’t, they seemed comfortable with what was going on. They had certain areas taped-off.

    Of course on the first night I was there, the new fissure opened in front of us and they really DID get into gear, chasing everybody well back from the vent area!

    It’s impossible to really police a mountain top, and (to risk stereotyping) I got the distinct impression that Icelanders were a tough independent people who wouldn’t have very much respect for police telling them where they can and can’t go on a mountain top – although obviously things are different when there’s a very clear reason, like a new fissure!

    April 3, 2010

    @Jon – now I see what you mean. At this instant it’s a thin white line running across, to the left of the first cone and above the lava flow? Hmmm, yes that very well could be a fissure. Or it could just possibly be a row of lights from Jeeps up on that hill; there were many all lined up in that area when I was up there. If it IS a fissure I hope they’re not there now!!!

    The steam explosion was some distance away from there, down near the lava flow as I saw it.

    @Henrik – no, the live feed conveys *nothing* of what it’s like to be up there! I’ve been up close with lava on Kilauea more than once, but this was much more intense. I don’t have time for a detailed report but I’ll try to throw some photos and video on a webpage tonight.

    Yes Victor, that’s what I thought Jon was referring to when he mentioned the steam explosion. I too wondered briefly about a new fissure, but it seemed to die down fast and was in the area of the lava flow, so I read that as lava encountering snow.

  387. #393 Jón Frímann
    April 3, 2010

    It is hard to see what is going on there at the moment. But there is something interesting happening east of the new fissure. The light I did see before is apparently west of the old crater. I got bit confused with the direction before.

    It might just be lava flow. Hard to know at this moment.

    April 3, 2010

    April 3, 2010

    @Firema, that would be correct. I think.

    I must point out that the harmonic tremors indicate that the pressure is increasing again in the eruption, and that it looks like that the two vents we currently are watching can’t handle the flow properly it seems.

    @ Viktor Sorry Viktor, I made a mistake. Of course there are two pictures you made! So we discuss the two lights. I think it is the same second fissure but the middle part is not active anymore so it seems like a new fissure in the night.

    Henrik I think you would be more likely to find Topaz in that environment….or maybe Red Beryl. I know they do find Corundum in Australia and Montana in basalt. I have also heard of Corundum being found in pegmatites in Alabama and North Carolina. I usually look around the margins of Dunites or what used to be Dunites which have undergone retrograde metamorphism to Soapstone or Serpentinite.
    en.wikipedia.org/wiki/Dunite

    There is a really cool place in North Carolina called Chunky Gal Mountain you would love…..here are a few links to pages with pics on them. I will try to dig up some pics we took there a few years back. These links will give you an idea of the place…. oh and there are lots of really nice rhodolite garnets there;)

    April 3, 2010

    Hi everyone
    Sorry – it wasn’t me passing the webcam. I was way too busy looking at the eruption!!!! Yes – I DID go up there on thursday evening/night. We were alowed to go to around 800 meters distance because of the new-crack-opening-event on the night before. And maybe Im not the “normal” type of volcanologist – but I felt no need to go closer. Is quite powerful and not to be joked with. The evening was an amazing trip by super-jeep and snowmobile across the glacier. About 1½ hours at the eruption all together and then back on the snowmobiles in the night.(Thanking Chris for doing the driving and for being very good company). So -I WAS exchausted when I got back to the hotel at 2 am – but not from trekking – just from all the impressions and a VERY long day. A friend was kind enough to borrow me a really expensive camera for the trip – so I hope to have caught som awsome pictures!
    My best advise: Just go there! It’s rather accessable and the Icelandic tourist-companies are doing all they can to give as many people as possible the opportunity of getting there. It will cost you some money – but it’s worth it!
    It can be done quite safely – if of course you disregard the fact that a volcanic eruption will never be “safe”…
    So get your XXX’es out of the office and away from the computer – and GO!

    I am thinking that we really do need to revisit the subject of Etna here. More than half of the eruptions of the past 600 years have occurred in the 20th and early 21st century.

    Curiously, we note that the eruption duration of each cent event has progressively increased since 2000. This volcano is worthy of close study.

    This is a volcano with a serious case of ultra-cool.

  400. #406 Diane
    April 3, 2010

    @Randall, thank you for your generous offer of a 4 leaf clover! You must be good at finding them. Where my folks lived, they had a pasture that must have had a strain of them because I would look down and find them all over the place. Big tall ones, too. That pasture is no more so I don’t think the clover grows there anymore as it gets mowed regularly. *Sniff, sniff* And thank you for your comments on my poetry. Eventually I will post the whole poem when it gets written.

    I have been to an area in Montana where you can find corundum laying on top of tailings if you know what to look for. I want to go back there and do some panning, too. The only bad thing about it is the mosquitos and western diamondbacks. I don’t know which is worse. I think the diamondbacks.

    @Passerby, yes, Etna also needs some monitoring. And it can be a fickle mountain with all kinds of surprises from Strombolian spouts to 30′ walls of aa lava flow that creeps along and takes everything with it. Let’s hope that the next eruption will be one that will put on a show and not hurt anybody or anything. Something tells me, though, that the quakes Boris mentioned and the pics of the damage it did are saying something about what may be coming. An eruption for sure. When? Who knows?

    Not so difficult to forecast a new eruption at Etna, Diane. Etna is not our Sleeping Beauty Eyjaf.

    Etna sounds like clockwork, with a periodicity of ~18-24 months.

    Perhaps she will start with bang, and we may see something that has not happened for a very long time.

  403. #409 Jón Frímann
    April 3, 2010

    @Randall Nix, thanks for the clover offer. :-)

    The dot at the west side of the old fissure has returned. It does not look like a lava. But it well might be. It is hard to tell at the moment in the darkness.

    I now fear that we might see a new fissure opening nearby the current two fissures. But this fissure that I think might open is most likely to open near the cliffs end and even split them open. Something that has not been seen before. But I might be wrong about the seeing part. The rest is just a big question. But there are clues to this already. As it appears that the pressure in the current went appears to keep increasing for some reason, while at the same time something is blocking the opening of the fissure under the glacier (the glacier it self?).

  405. #411 Randall Nix
    April 3, 2010

    Diane yes I am very good at finding them here in our yard. I found 40 last year and 27 this year, I also found a 6 leaf last year. We give most of them away to people who need them….these have proven to be VERY special 4 leaf clovers;)

  406. #412 Diane
    April 4, 2010

    Randall, I have found 5 leaf ones, too, and also 6 leaf. I have not been 4 leaf clover hunting in a long time. Once I was outside at a college and as I was waiting for a class to start, I was looking for them in the yard area between classrooms. I found some. Where I live now, it is hard to find because we have bur clover here and that stuff doesn’t have them. But I may get somewhere where I can look for them. If you spend time at it and happen to be where a strain of them, you can find them. I do believe they can come in strains. At least it seems that way. It is fun to look for them and a nice passtime, too. Just like panning for that yellow stuff.

    There are some people who belong to the club who can tell you just by looking at your gold where it came from. At least where it came from in CA. Have you ever seen Aussie gold?

  407. #413 Randall Nix
    April 4, 2010

    Diane no I haven’t ever seen any Aussie gold. I have only found it in Alabama, New Mexico, Colorado, North Carolina, Georgia and Arizona.

  408. #414 Diane
    April 4, 2010

    Randall, Aussie gold is a beautiful bright shiny yellow. Very pretty stuff. The gold I have seen around here can be reddish in color and also have more silver in it at times. Other than that, it is a dull yellow.

    The president of our club pulled a fast one on one of the members one time. He told the guy that he would clean up a nugget he had by putting it in some nitric acid solution. When the guy wasn’t looking, he switched to a much smaller nugget. When he saw that he just flipped. Then they told him what they had done. Too bad it wasn’t an April Fool joke. It would have been a good one.

  409. #415 Boris Behncke
    April 4, 2010

    @Holger (#408) – yes, they did fill some of the larger cracks quite fast. But that’s extremely untypical of Italian (especially Sicilian) road maintenance, you won’t imagine the state of most of our roads and highways here.

    @Passerby (#406) – Etna does indeed erupt very frequently, so generally you can hit it at any given moment (unless it is in eruption already) if you say it will probably erupt within one or two years. But when it comes to the details, it gets tricky. Will it be a summit eruption (not too dangerous but totally spectacular, as Diane here will confirm), or a flank eruption (potentially devastating)? Will it produce little ash or a lot (problems for air traffic)? Will it occur on sparsely populated western flank or on the densely populated southeast flank? How high will the lava emission rate be (a fundamental factor in determining whether the lava will reach populated areas or not)? Will it build itself lava tubes (which permit more efficient transport to greater distance)? All these questions are to be asked, and currently there’s no means to answer them. So, we have to wait for further signs from the volcano.

    What we do know is that she’s swelling; the swelling started even before the last flank eruption ended. So that’s a remarkable difference with Mauna Loa, which for the moment has stopped inflating. Etna inflates virtually always when she’s not erupting, because she is constantly fed with magma.

    We would certainly love to see again what Diane has described, the incredibly awesome lava fountains (that’s quite more than Strombolian activity) rising up to 1000 m or more above the vent. We had 66 such lava fountains in the year 2000. In 2007-2007 we saw 7 of them. I think in its whole life, which is now 39 years long, the Southeast Crater (youngest and most active of Etna’s four summit craters) has made around 300 of these lava fountains. Yes, Passerby (#401), Etna is a serious case of ultra-cool. Also because in spite of all the studies and all the monitoring (which is now at the same standards as in Hawaii) Etna retains quite a lot of mystery.

    “The Vodaphone webcam works for me. If you can’t get fresh images try setting your system time zone to GMT. For some reason images don’t get updated if your system clock is different than what the page expects, or at least this was what occurred to me with Mozilla Firefox 3.6 and Windows 7.”

  432. #438 Boris Behncke
    April 4, 2010

    Vodafone has never worked for me. Neither on my home computer, nor in the INGV office.

    As for the new gas columns, whenever you see dense white plumes rise you can be almost certain that it’s lava flows interacting with snow, not new vents. From experience on Etna and collaborating with other scientists on volcanoes like Klyuchevskoy and Llaima, it seems established that when new fissures open across snow or even glaciers, they produce virtually no (phreatomagmatic) explosive activity and very little vapor – it’s the lava flows that interact more vigorously with snow. That is probably because in the immediate vicinity of a new vent all snow melts or evaporates nearly instantaneously, without having a chance of interacting with hot magma in the vent. The most violent explosive events we’ve seen so far during this eruption in Iceland has occurred where lava mixed and interacted with snow, especially where it dropped into the deep gorges. The problem with such explosive interactions is that they can occur at distances of up to several kilometers from the eruptive vents, and they can produce small pyroclastic flows.

  433. #439 Randall Nix
    April 4, 2010

    Henrik it sure looks that way.

    Chunky Gal is really neat place….the tourists go to Franklin North Carolina for rubies but the serious hunters in that area go to Chunky Gal and Buck Creek.

  434. #440 Boris Behncke
    April 4, 2010

    ahahaha … now Vodafone works for me.

    What I find interesting is that the lava flows from the second fissure never seem to go very far. That means, the rate of lava emission is quite low and pulsating, so that rather than forming a stable channel or even a lava tube, the lava forms in recurring surges, and often changes directions. The same has occurred during much of the latest Etna eruption, lava flows did not travel far and thus gradually accumulated to ever greater thickness as one lobe piled upon another.

  435. #441 Henrik
    April 4, 2010

    Boris, are you saying that the lava from the second vent is more viscous than that of the first vent, or that they are of similar viscosity but as the second fissure has a much lower rate of emission, sustained lava flows do not form? Or is it a combination? What about a temperature difference, with the first vent producing substantially hotter lava, therefore less viscous?

  436. #442 Viktor
    April 4, 2010

    In daylight you can hardly spot anything on the webcam, but steam.
    Still, it seems to me that the 2-3 minute activity during last evening was not necessarily only lava-snow contact.

    http://extras.vodafone.is/trailers/fimmvorduhals/mx10-4-235-80/2010/04/04/10/16.jpg

    It’s true that there is a straight line of lava coming from the second vent, going to the left. However, on the left side, maybe 200 meteres behind that line, there is a constant, concentrated source of steam, just like near the two original vents.

    Also, there is a recently appeared dark plume, just in front of the flowing, which is perhaps a new lava fountain.

    I wish Mila would move the Fimm cam back much closer to the spot.

    @Passerby (# 442). I do not doubt that you may be correct. What I marvel at is how you can arrive at such a firm conclusion about the thoughts behind the words of others. Since mind-reading is not part of any curriclum, I have always found it wise to let other people speak for themselves, and if I do not completely understand what is said, repeat what I heard. This is very basic communications strategy, taught at freshman level at most half-decent universities.

    Since I know very little of your field of expertise – a failing I share with most people posting on here I dare say – could you please explain to us how you read that from Soucel´s graph. I am afraid that by not stating how you arrive at your conclusions, you violate one of the most basic principles of good science – repeatability.

    The cams offered on the web are disappointing, all from very far distance. It should be possibele to get a closer web cam view by now. Tourists are swarming very close to the vent though, very strange!

    the vodafone has had it’s zoom pulled back after the nasty storm the last couple days
    Fimmvörðuhálsi appears to have been relocated from what was a good location to a lower location and further away and/or the zoom was taken out entirely
    Þórólfsfelli needs a higher zoom but it has a good location

    Boris’ could not have stated his meaning more plainly. He did not say that there was a change in apparent viscosity. You questioned meaning, despite the succinctly stated observation of a change in _lava emission rate_ and pulse timing.

    You violate the most basic of discussion community rules, slyly sliding in wearing ad hominem attacks into posts, repeatedly.

    If you cannot read a graph, that is your problem. Twice before there have been large excursions in depth with concurrent jump in seismic activity with matched appearance of new fissure emissions. The last rolling graph excursion also coincided temporally with the third report of webcam evidence of new source of lava eruption, but much smaller scale than previous fissure activity and this also matched visual evidence.

    How is this hard to recognize? It is a simple, repeating pattern.

    No news of a third fissure anywhere, neither on Icelandic newspaper web sites (Mbl, Visir, Ruv), nor on the IMO and Nordvulk sites. And watching the webcams, I miserably fail to see anything indicating that new vents have opened up. Though in the archived images of Vodafone early this morning there was a number of glowing spots in a strange position, to the right of the second fissure, but these were most probably lava taking a more westerly course, around the cones that have now built around the vents of the second fissure. The steam explosions seen later today were further evidence for lava flows, not new vents.

    As for the low lava emission rates, Passerby (#442) got that right, it’s a question of cooling and thus being not able to flow very far – not that much one of viscosity, which is determined rather by chemical composition, gas content, and temperature. But what we can’t see in the webcam images is how much of the lava is possibly flowing through tubes – because from the news reports I gather that the lava has advanced a bit further down the large gorge north of the active vents. That way it wouldn’t be visible via the web cams but it would actually have created itself a most efficient means of transport.

    A useful tip for viewing pictures/video or even reading small print on the Internet. This works with Windows XP, Vista and Windows 7.

    Hold down the “Ctrl” key and press the “+” key to zoom in and the “-” key to zoom out. This will affect only your active browser window.

    Oh yeah about 6 hrs a day/night on average;) I work on the computer and from home most of the time so I have a very non-linear type of work day/night…unless I am working on one of the Navy Bases that day….then it is early to bed, early to rise.

    Good morning to all. Well, it is morning here still. :-) I got up very late 9am or so.

    Gordys, I think Randall does catnap. Right Randall? ;-D BTW ,thanks for the tip on zooming. I did not know how to do that.

    Motsfo, yes, Islandic eruptions are far different from Redoubt. That pic you sent was an awesome plinian blast. Just like last year. The ash is not so nice.

    I just wish they had not moved that cam!!!! Maybe they could have just moved it back and then zoomed in.

    Villard, thanks for that link. Methinks he was awefully close to that flow! Right on the edge! The film did show what takes place at a fissure. I don’t understand Islandic, but I knew what he was talking about when he mentioned lapilli. There was a lot of that, for sure.

    Happy Easter from Sicily, though here it’s already evening. The news here is no news, Etna has returned to calm after more than 170 earthquakes on the Pernicana fault between 2 April evening and 3 April mid-day.
    Let’s hope it’ll give us a few more weeks of peace, and especially, no overlap with Eyjafjallajökull-Fimmvörðuháls, because otherwise how to choose between all the webcams you guys, and I would no longer be able to watch the Iceland show at all.

  463. #469 Diane

    Boris, that would be a near tragety if you could not follow what is going on in Iceland! But, then, Etna is a volcano and I suppose once in a while you could mosey on over to see what is going on even if only for 5min. Of course, the “Old Lady” just may cooperate. :-)

    @469: from which webcam? I’m unable to notice that. Can you post a screenshot.

    By the way, as the low frequency component of volcanic tremors (0.5-1.0 Hz) increased slightly in the last few minutes, steaming from the volcano also appeared to increase sensibly, at least from what I see from the Vodaphone webcam.

  467. #473 Fireman
    April 4, 2010

    Optical illusion I think… OTOH, the lava flow we spotted to the West (right) side of the cone yesterday has hit snow on the edge of the cliff and is making an impressive steam plume ATT.

  468. #474 Akira Shirakawa

    Is that a new fissure under the steam????? look like a lava plume.

  473. #479 Fireman
    April 4, 2010

    @Erik W: if you look back to yesterday evening on the Vodaphone cam, you will see a lava flow working its way down that side of the cone. It seems to me that the plume was most likely due to that flow finally hitting snow above the edge of the cliff there; we’ve seen similar plumes from other flows on more than one occasion.

  474. #480 Gina
    April 4, 2010

    where the last steam came from there is a darker plume starting yet to me it looks as if it is internally light hard to tell as it is in the sun

  475. #481 Erik W.
    April 4, 2010

    @Fireman I would say there is a new eruption where that steam vent was on the right hand side of the second fissure.

  476. #482 parclair
    April 4, 2010

    Well, it’s getting to sundown If there’s a new fissure, we’ll be able to see it. We need to look for straight up jets of orange. Puffy orange will probably be steam lit by lava.

  477. #483 Henrik
    April 4, 2010

    19.39 GMT Steam explosion (smallish) to the west of the vent. For about 10 mins prior, the whole vent (from l to r in front of old cone) seemed to be producing small lava fountains (Vodafone zoomed in, thx Gordys, Anne!). Looks like another lava flow.

    April 4, 2010

    zoomed in at 260% on Vodafone it looks like maybe another vent opened in front of vent 2…..I see 2 jets there one if front of the other and I don’t think it is the first vent we have had all along either……..what do you guys see?

    that’s on vodafone zoomed in close.

  485. #491 Viktor
    April 4, 2010

    IF it is a new fissure, it corresponds to the 3D EQ map on Vedur site:
    http://en.vedur.is/about-imo/news/2010/bigimg/1859?ListID=0

    The shallow EQs (referring to underground magma movement) were located W-NW from the first opening, around 2-3kms long, and this new steam source is also in that direction.

    Though, last evening’s bright activities were also fissure-alike, but probably were simply magma vs snow explosions.

  486. #492 Randall Nix
    April 4, 2010

    Before it got too dark, there were four vents discernible – three on a line E – W with the middle one the largest, and one vent more or less at right angle to them and some way (1/3??) up the slope of the first scoria cone.

  490. #496 Henrik

    The westernmost “vent” seems to be, not a vent, but part of the lava flow. When the steam relents, you may see the flow glowing right at the place where steam explosions have occured. Zoom in!

    Vodaphone camera.

    Well, it looks like flares to me.

    Still not sure, though. I’ve been watching the hot spot between eruption 2 and the new /flare/steamy area the last couple of days as a potential new eruption, but have come to the conclusion that it’s a lava flow. The new steamy areas is downhill from there.

    But, the new steamy area doesn’t seem to be behaving like the lava stream heading to the left from eruption 2.

    Happy easter everyone!

    I was checking the GPS data and the inflation to the west is a dangerous one. But this whole thing did start when Eyjafjallajökull started to inflate to the west. The deflation to the south is not the main issue it seems. But in 1999 it did inflate to a 10cm and nothing happened. What has normally happened when a the west side of Eyjafjallajöklull inflates the south part usually follows by a day or two delay.

    This means that the pressure is increasing in Eyjafjallajökull at interestingly fast rate it seems.

    BTW, Mammoth is still quaking away with the depths being around 3 miles. It is not like a major swarm, but it is consistently getting around maybe 20 quakes/week sometimes less. Also the area south of Long Valley caldera gets just about as many that are scattered over a rather large area. Once in a while there will be one in the caldera itself someplace. I don’t think this means an eruption at Mammoth, either. Most of the quakes are techtonic as there a couple of faults on Mammoth. At least that was what the seizmologist told me that I was in contact with and lately he has not responded so I have left him along. I figure he is too busy to communicate with me right now. Another issue at Mammoth is the CO2 seepage and the kill zones. I have mentioned it before that the geologists that are studying Mammoth think there might be a large reservoir of CO2 under the mountain. That, along with the snow, might be responsible for some of the quakes, especially if there is magma movement, which I haven’t heard of any inflation there. I may just check on that.

    On the earthquake. EMSC has upgraded it to Mw7.0 earthquake at 10km depth. This earthquake had a ML3.3 trigger event that happened just before the main big event.

    I do not know if this is going to have any effect on Eyjafjallajökull eruption. But it is going to be interesting to see if it does. But the theory says it is not going to.

    BAJA EQ fits the pattern of ocean ridge with fast spread rate acting under exogenous, massively coupled induction forces.

    Interesting.

    I do not think we are done flexing on the Eastern Pacific Ridge. Appears that it’s transfer walking north.

    Figures, CA got record rains with the rolling storm express this winter and are at last not facing severe shortages entering the irrigation season.

    Major fracture pore pressure.

    Seattle, Portland, or Juan de Fuca maybe.

  532. #538 Diane
    April 4, 2010

    Jon, I don’t think this quake will have any impact on Ejaf. It could if the condions are right for it to, but I have my doubts. You will know shortly if it does.

    There have been a series of 3+ quakes along with the 6.9 (7.0) in S CA as well as the 5.1. It will be interesting to see how far this goes as it probably will affect the San Andreas. That fault breaks up along side of the eastern area of the Salton Sea and then south of that the Imperial Fault appears and I think it is actually the San Andreas that continues south into Baja Mexico and then into the Gulf of CA which is a fault feature. It is all part of the Pacific plate that moves N in reference to the North American plate.

    I am sure Randall will keep us up on this and I probably will put in my two cents worth, too.

    The news report said that the tall buildings in LA were swaying and it was felt in Phenix. Yuma may have some damage as it is pretty close to it. We will see how much this has affected the whole area soon. I know there will be some damage in S CA because it is close.

  533. #539 StarBP
    April 4, 2010

    So, about the recent Yellowstone quakes, could someone please read the signatures and tell me whether they are magmatic or not? I doubt they are, but just wondering. Since they are under 1/2-mile apart, they most likely have the same source. I just don’t know what kind of source that is.

    @Jon 519, I was noticing that inflation to the West also. It has been 10 days since it has moved much more than a mm a day. Deflation on North, deflation on up, it is a fluid system. My thoughts are that I would be much more concerned if I saw inflation in all directions…but an anomaly in one direction makes me go hmmm… It will be interesting to watch what happens.

    I am glad that the zoom tip helped out(thank you also Anne 465).

  552. #559 Diane
    April 4, 2010

    Gina, I am aware of that geothermal area. They have taken the 4.0 and 4.1 off the map. The seizmologist I talked about earlier told me about the reinjection of water there. Thanks for letting me know it was the same corp that started quakes elsewhere.

    Parclair, yes, CA gets lots of quakes. I have been monitoring them since I got on the internet. Minus the geothermal plant, there are about 350-550/week. We are doing much better at detecting them now than when I first started watching. At that time there was only about 250/week.

    I have noticed several quakes along the border with Baja and that could affect the border and offset it a bit if they get strong enough. Not sure about that at the moment. There may be some slight offset that is insignificant, but you never know until surveyed.

  553. #560 Erik W.
    April 4, 2010

    I’m a little confused about the concern over Yellowstone. Over the past years Yellowstone has seen swarms of hundreds of earthquakes during each period. I would be concerned if you were seeing inflation on the increase. Last time I checked it wasn’t doing much.

    From GVP website.

    The Cerro Prieto geothermal field is located at the head of the Gulf of California, 35 km south of the city of Mexicali.

    Cerro Prieto lies in an active continental rift that is transitional between the transform San Andreas fault system to the north and a spreading ridge of the East Pacific Rise in the Gulf of California to the south. The only surficial volcanic feature at Cerro Prieto, which is located near sea level on the Colorado River delta, is a small, 223-m-high compound dacitic lava dome.

    (this ridge-transform fault system explains the northward walk energy transfer mentioned earlier)

    A 200-m-wide crater is located at the summit of the NE-most dome. The Cerro Prieto dome was roughly estimated from paleomagnetic evidence to have formed during a series of events between 100,000 and 10,000 years ago.

    Cucupas Indian legends described a monster that covered the land with hot rocks, which grew through the soil and emitted fire tongues, a possible reference to the growth of the volcano.

    The Key Phrases here are Eastern Pacific Rise, eastern pacific ridge and transform fault systems (San Andreas).

    Erik W, I know what you mean. I will say that I thought I saw some steam streaming to the right. I also thought I saw a very small faint light just to the right of the large blob of light which is probably the eruption. My guess is it was probably a jeep with some tourists. It was well away from the fissure.

    Maybe it is the moon shining through some clouds above the fissure.

    Moonrise over Katla. Full moon, or just past it. I saw such a moonrise about a month ago and wasn’t sure what I was watching, just kept tracking it over an hour or so to see if it rose and moved westward.

    Sanity check here folks… someone have a look at the Fimmvörðuhálsi cam (the only one currently working) and tell me… is that something new, considerably to the left of the original fissure? It appears to be slightly *above* the level of the scoria cone, so unless lava can flow uphill…

    Of course, I could be being deceived by perspective; it’s difficult to get the geography straight at night; it *could* just be lava hitting snow downslope away on the other side from the cam.

    Please stop babbling like children about a stupid moonrise. They’re syncing their camera feeds for the day, it’s early morning in Iceland.

    We got something MUCH MORE INTERESTING here – the probable causal mechanics of a bigass earthquake that sent major shockwaves northward along one of the most active transform fault systems on the planet, which runs through a very heavily populated metro center.

    This event is startlingly close in system components similarity to our Eyjaf in Iceland.

    From the link above:

    This area of the Baja is where the Cerro Prieto Geothermal Field (CPGF) lives, one of the largest producing geothermal fields in the world. It is also one of the few places where a spreading fault performs on land. They normally occur in ocean floor ridges. Because of this rarity and because of the manner in which the field is exploited to produce electricity, the geothermic field is closely monitored.

  606. #613 Jón Frímann
    April 4, 2010

    I managed to record most of the earthquakes in the latest swarm that did happen in Eyjafjallajökull. Most of the earthquakes where magma related, as the magma was cracking rock to push it self up trough the crust. This also indicates that the pressure is increasing inside Eyjafjallajökull again, it seems.

    I see that the large earthquake that did happen in Mexico has triggered many other small earthquakes. Lets hope that it doesn’t trigger any other big one.

  607. #614 Diane
    April 4, 2010

    Just a note on this quake we have had in Baja. A geologist, can’t remember the name, but I think it is the same man who wrote “Assembling California, has indicated that the Gulf of CA will eventually open all that area up and will end up in Nevada. If you look at the quake map of CA, you can see that the spread will take place along not only the San Andreas, but also the Sierra fault zone in the eastern part of the state. I asked the seismologist about this and he said it is true and that it would probably take millions of years to get to Nevada. Nonetheless, it is spreading and the sea will evenutally be up where the Salton Sea is now. It is my understanding that the water has been up into CA before so it is no surprise that it could get here again.

    As for the geothermal plant in Cerro Prieto, I haven’t heard of what is going on there right now, but I bet they have some damage. Certain of it. It will be interesting to see if that volcano erupts.

I like especially the ones with the northern lights, they have some stunning beauty not just for the colours but I think it’s really cool to have the power of our Earth and our Sun on the same image! How did your kids ( I think they are yours) enjoy the show?

    You see that USGS US EQ Map? Look where the swarm pattern diverges towards the western border of Nevada.

    Here’s why: Geothermal activity.

    Enel opens two geothermal plants in Churchill County.
    April 15, 2009

    Dignitaries and representative from Enel Green Power officially dedicated on Wednesday two new Churchill County geothermal plants which are (among) the largest in the world.

    http://www.lahontanvalleynews.com/article/20090415/NEWS/904159989

    This is what causes some concern. 2006 article on a super sized geothermal plant. Where? North Sumatra.

    http://thefraserdomain.typepad.com/energy/2006/08/ormat_to_build_.html

    This uptick in geothermal field activity would explain also the sudden uptick in Yellowstone and Mammoth Mt geothermal seismic activity.

    And, it describes some of the persistent recent earthquake seismic centers in Iceland.

    Ahhhhh.

    Here’s the latest on the quakes news-wise

    http://www.signonsandiego.com/news/2010/apr/04/69-magnitude-quake-shakes-san-diego-region/

    Unfortunately, someone died. Search and Rescue have gone to Mexicali, houses collapsed. What surprises me is that such a deep quake caused damage in San Diego.

    Re: lit up

    This area has been quaking a bit for the last year. (I’ve been watching). Some biggies, lots of small– ie, clustering. Also, a quake this size will have tons of aftershocks, as the earth twitches itself back into equilibrium.

  615. #622 Passerby
    April 4, 2010

    Just to clarify: the power plants sitting on large geothermal fields aren’t causing the earthquake swarms, as much as adding additional pore pressure stress, an ill-timed extra stress-strain push during a period relatively rare (2-3 times a century) crustal expansion flexing that is most pronounced at shallow, divergent ridge centers in response to larger physical field fluctuations, with an additional temporal component that has occurred only once in the past 100 years.

    I hate to sound like a broken record, but can somebody look at this web cam of Katla http://www.ruv.is/katla and give me some thought on it. The bright light source and smoke have been there for over two hours.

  617. #624 Diane
    April 4, 2010

    It is the same geologist that wrote “Assembling California that predicted the Gulf of CA would be coming back and head into Nevada. He said this long before there were any geothermal plants. However, I can see how these plants might excelerate the process a bit and affect other areas. Thing is, I am not sure how far the effects will be from the plants. One of the plants in Nevada is right along I80. You can see the steam coming out of the ground. I can see why they want to use the geothermal areas for power because it is cheaper and available, though maybe very dangerous because of the faulting and magma chambers below. It will be interesting to see what has happend to the plant in Baja and what the implications are, and if it has wakened that volcano.

    @Passerby, the path that the quakes you see heading into Nevada is exactly the path I am talking about. That is what the geologist predicted. I wish I could remember his name! Oh fiddle.

  622. #629 George
    April 5, 2010

    “that predicted the Gulf of CA would be coming back and head into Nevada.”

    I have read that as well. Eventually the area that is now the Salton Sea, through Death Valley, all the way up to the dry Lake Lahontan region will probably be under water as the Sea of Cortez extends Northward.

    But none of us here will live to see it.

    In fact, while the current Salton Sea is an accident, the area did flood naturally at periodic as the course of the Colorado changed and it burst its banks from time to time. I read fairly recently (within the past few years) that it is estimated that the region had dried from the last such episode only shortly (within a century or so) before western explorers arrived in the region.

    well, now that I said that, there is a huge glow appearing on the Hekla cam right now that I can only imagine is breaking dawn but it seems a bit early, everything is still black as pitch here in Germany.

  624. #631 bruce stout
    April 5, 2010

    well, lord knows what that is… maybe atmospherics. It’s not showing up on the Vodafone or the Katla webcam. But there are two very bright patches showing on the Hekla cam. Most strange.

    April 5, 2010

    @bruce stout, daybreak is now around 05:30 UTC here in Iceland. But the night is getting shorter by the day. There won’t be any night around 20th of May or so.

    But it appears that the eruption got a huge energy spike tonight for some reason.

  626. #633 bruce stout
    April 5, 2010

    Morning Jón!! I’m looking forward to daybreak to see if there has indeed been any change. The Hekla cam is showing two small intense patches of glow that I take it are lava but if so they look too far apart to be the two original vents and above both of them is a lot of glow in the sky. Maybe lava has started going over the cliff in a new direction.

    PS are you up early like me or just late to bed?

  627. #634 bruce stout
    April 5, 2010

    well the two intense patches have disappeared leaving only the background glow, which is obviously the site of the vents. Looks very much like lava went over a cliff or a steam explosion occurred. Daylight will reveal all!

    There is a steam coming up in a intresting place. It does not appear to be lava related, or at least I don’t think that magma has been flowing in that direction. But the location is to the west, near the cliff edge.

  631. #638 Randall Nix
    April 5, 2010

    Jon I see that but I think it is a lava flow hitting snow. I do think there are 3 vents now a new one in front of the #2 vent.

  632. #639 Jón Frímann
    April 5, 2010

    @Randall Nix, I did first think it was also a lava hitting the snow. But I am yet to see that lava as a dark rock there, like the rest of the lava in the area. But there also the issue of the fact that lava does not run upside yet to my knowledge.

    There is something going on there and it doesn’t appear to be lava.

    I find a bit surprising the increase of very low frequency component of volcanic tremors manifesting itself mainly (proportionally speaking) on HVO station, which I suppose it’s a shorthand for Lágu-Hvolar, a station located a few kilometers South-East of the Katla caldera. This could be either the result of regional weather noise (as you can see from webcams – or better, can’t see), or instead, magma injection at high depths since all stations are recording about the same increase since about the same time.

    Say. Has any of you (I know Randall has) checked out the S CA quake map lately? Last time I checked it out, about half an hour ago, there were 491 quakes listed and that includes the 7.2 and a 5.1 near the border that was at 0.0 depth! I bet that one, if it was actually close enough to the border to do so, could have shifted the border some.

    I guess we can check the rest of the world and see what is going on as far as volcanoes are concerned. I have to go to town *sniff sniff*. Catch everybody later.

    RE 559

    @Randall
    It amazed me when I read the reports that the Denali quake could cause changes in yellowstones hydrothermal system with the distance between them being so huge
    yet it is possible for 7.2 quake a paltry 400 miles away to influence a volcano especially if it just a little unstable to start with I think the key is how well the bedrock couples the motion/energy and so. calf in a mess of faults that probably wont couple to much energy from the quake to the longvally system

    Gina when I checked LV late last night there hadn’t been much activity there before, during or even after the 7.2 quake…the Yellowstone swarm started the night before the 7.2

    A 9.0 is like the energy release of 32 billion tons of TNT….a 7.0 is like the energy release of 32 million tons of TNT….BIG difference in the two.

  660. #668 George
    April 5, 2010

    “calf in a mess of faults that probably wont couple to much energy from the quake to the longvally system”

    Yes, here in California quakes damp out fairly quickly with distance because everything is so broken up. Imagine one of those desk toys with the balls hanging from a pivot and you pull back the ball on one end, let go, and it swings down to hit the row of balls and the one on the end flies out. Now imagine you replace one of the balls with a beanbag and you have sort of the situation in some areas of California.

    That said, California has some faults that can rupture for great distances so the notion of “epicenter” might go out the window when 100 miles of fault slips, as can happen about every hundred years or so. The Southern end of the SAFS has been quiet for some time now. The middle section hasn’t moved much since the Ft. Tejon (c. 1857) when over 200 miles of fault slipped in one quake.

    The frequency of M 8-ish quakes is, I believe, about every 100 years or so on the SAFS with the average being about every 300 years for any given specific location.

  667. #675 Diane
    April 5, 2010

    @Gina #663, the strenght of quakes from 1 on up is a logrithmic scale of 31. That means a 2 is 31 times stronger than a 1. So a 9 is so much stronger than a 7 that you almost can’t compare it. Both are very stong, but a 9 just does some much more damage. Another thing that affects how far quakes affect things is how long the earth shakes. A short 7 may not do as much damage as a long 5. Also the depth of the quake has a lot to do with how much damage is done.

    East of the Rockies, quakes are felt farther than they are here in CA. A 4.5, say, in LA would not be felt were I live, yet a 4.5 in Illinois can be felt for 300 miles. So topography also has an affect.

    I hope this helps, as well as what George said, you to understand it a little better. If the quake is strong enough and the P and S waves hit right, quakes from far away can affect things. Conditions have to be right for that to happen.

    Cheers

    Fascinating discussion. Thanks Everyone. Being a life long amateur meteorologist, I was wondering what the effect of low barometric pressure on magma flows and seismicity is?! Does this allow magma to rise more as tides would at sea when a deep atmospheric depression passes over, or does the force of the rising magma – more than cancel it out anyway. With a 969mb and lower depression over Iceland at the moment, I would have thought it would have some consequence. It is well known that the sea bubbles up opn a large scale when pressure is low.

    JUST A meandering passive thought. I notice interesting seismic activity this morning, but I maybe correlating and probably are – incorrectly.

    Your thoughts please?

    George I still can’t see that but if you look at:
    eldgos.mila.is/eyjafjallajokull-fra-thorolfsfelli/
    Hit control and + and bring it up to about 300% and then look to the far left of the pic and you will see a steam plume where there shouldn’t be one on the inside of that ridge just below the rim.

    Randall, it is hard to see at the moment because of that dark cloud above it that has now moved in, we are going to have to wait for that to pass, but there is a darker material, look closely at the edge of the ridge. You will see it moving left to right once that passes.

    I believe your right,im watching on a 42″ in 1080 and the steam is slightly distinguishable as different from the cloud backdrop and is covering that cliff face.
    Pity theres not an infa red cam.

  692. #700 George
    April 6, 2010

    It might also be tricks of the light. Wind gusts could be picking up puffs of snow and with the low light angle, it could appear dark. We are going to have to wait for the weather to clear, I suppose.

  693. #701 Henrik
    April 6, 2010

    Jonathan! The interest in EQs is because each change in the eruption, such as when the second vent opened, has been heralded by EQ swarms – some 4-7 EQs magnitude ~1.1 – 2.8 within the space of a minute at different depths. When the first and second vents opened, there were +2 EQs at 0.0 km depth, so every time there are EQ “swarms”, a large one (M2.5+) or at zero or very shallow depth, our pulses rise. At other times, an increased EQ activity has heralded an increase in the eruption a few hours later.

    George! What your pictures seem to show is a lava flow eating its way through snow. That the clouds seem dark may be a result of the light conditions. Compare with other low clouds! I’m not saying it’s not a new vent, it may very well be.

  694. #702 George
    April 6, 2010

    “George! What your pictures seem to show is a lava flow eating its way through snow. ”

    Could well be because I believe that the initial lava flow from the original vent flowed in that direction.

    But what causes me to temper that thought is the fact that it doesn’t look like steam, seems to look more “ashen” to me.

    I would expect steam to be about the same brightness as the clouds, even the dark ones. This material seems to be much darker like a lava fountain being blown in the wind might be expected to produce.

    If it is a new vent, we will have confirmation soon enough.

  696. #704 Boris Behncke
    April 6, 2010

    @George (#685 and following) – what you’ve seen there may be a new lobe of lava travelling a bit further north (that is, closer to the webcam relative to the previous flows from the first fissure), because over the past couple of weeks the lava from that fissure must have accumulated to quite some thickness. So a new flow will not travel on top of that accumulation but rather along its margine.
    I am fairly confident that in the moment a new fissure opens or something else of major proportion happens, this will be all over the Icelandic on-line newspapers like RUV, Visir, and MBL. They’ve been remarkably fast in reporting all of the more notable events during this eruption, and I bet my derrière that (at least some of) the journalists there are also clinging to the webcams :-)

    “I am fairly confident that in the moment a new fissure opens or something else of major proportion happens, this will be all over the Icelandic on-line newspapers like RUV, Visir, and MBL.”

    Yes, I agree, which is why I thought we would hear soon enough if there was a new vent.

    Boris I posted this yesterday and showed Erik he said he thought there was at least 1 new vent in these pics…blow them up and look at the jets…..what do you think?

  700. #708 Boris Behncke
    April 6, 2010

    @Randall (#704) – what we see in these images is certainly a large plume, though I failed to see clear evidence for explosive jets, the resolution is too low. Yet, such jets can occur even at a great distance from an eruptive vent simply when lava flows interact explosively with snow and ice, or water-soaked ground. Such explosions can even produce pyroclastic flows and are documented at a number of volcanoes, obviously including Etna but also Klyuchevskoy in Kamchatka and Llaima in Chile. I am working with a group of colleagues on a publication on this issue, because it does indeed represent a previously unknown hazard – explosive activity of this kind was known, but not its capability of producing pyroclastic flows.

    Seems to me there is definitely something going on at the left of the http://eldgos.mila.is/eyjafjallajokull-fra-fimmvorduhalsi/ camera. It looks like fountaining with steam generation to the left of it and steam coming from something going over the cliff.
    Then again I could have a fertile imagination but I don’t think so.

    Jonathan #689 I am not sure about the barimetric pressure affecting the current eruption in Iceland. I do know it does affect the CO2 output at Mammoth Mt. That is my knowledge of the subject.

    I guess the cam is down until Wed. :-( If there has been another fissure open up, we will have to rely on the news for a while.

    My take on the steam or jet is that it is lava coming into contact with snow as that is what it looked like to me. Has anyone checked the news? I haven’t gotten that far yet.

    Just noticed a large mag 3.5 EQ at 2.0 km depth, in the usual magma pipe location 5.8 km SV af Básum

    I think this is the fist one over mag 3 since Mar 21 or before. Sounds like lots of life is left in Eyja.

    Also, a 3.7 just inside the Katla caldera rim. I will make no conclusions on that one.

  708. #716 Andrew
    April 6, 2010

    The Katla quake that I mentioned in 713 started just 5 seconds after the 3.5 Eyja quake.

    In order not to alarm anyone, I will make the suggestion that the Katla quake was just caused by settling of fractured rock on the caldera rim, triggered by the Eyja quake.

    But I will leave it to the real experts here to come up with a real analysis.

  710. #718 Jón Frímann
    April 6, 2010

    The Katla earthquake is a SIL dislocation in the system. You can tell by the less quality of that earthquake.

    There is something going on in Eyjafjallajökull now. This might be a signal for a new fissure opening in Eyjafjallajökull where the earthquake did happen.

  711. #719 Fireman
    April 6, 2010

    OK the ‘new’ Mila cam is working now: It seems Valahnjúk is the new name for what was the repositioned Fimmvörðuhálsi cam; the original Fimmvörðuhálsi cam near the vents is going to be back tomorrow!

  712. #720 Andrew
    April 6, 2010

    Thanks Jón. I see now that the katla quake has been removed from the vedur.is report.

  713. #721 Henrik
    April 6, 2010

    IIRC the M 3.5 is also the largest quake since activity started over a month ago. At 2.7 km depth, it’s still “within” the current magma conduit, but most certainly something broke. To a layman, it’s hard to imagine that there will be no other effects than the quake. Let’s wait and see!

    PS. The Iceland Met Office does not show any other quake but the one 5.9 km SSW Básar.

  714. #722 Henrik
    April 6, 2010

    Both MBL and RUV carry the news. According to the MBL site, the EQ was a M 3.7, lasted for minutes and was the largest registered during the period of unrest:

  715. #723 Henrik
    April 6, 2010

    Iceland Met now give it as a M 3.6 at 0.2 km depth 4.2 km SW of Básar. This is just below the glacier(?) I wish the cloud would lift so we can see that area!

  716. #724 Andrew
    April 6, 2010

    I agree that this 3.5 or 3.7 EQ is big news and must indicate that a major change is about to occur at Eyja. The Met Office (vedur.is) has changed the reported quake details. It is now mag 3.6, and they changed the depth from 2.0 km to just 0.2 km, and moved the location slightly closer to the existing fissure.

    Still, this quake and the 3 smaller ones which have come after appear to be getting shallower. And they are all under the glacier.

  718. #726 Andrew
    April 6, 2010

    @723 Jon, Yes, I think these signs are an indication of Jón’s prediction starting to happen. Also, look back to comment #211 where Bruce Stout describes a scenario where a cap on the main magma pipe is forcing the magma to travel sideways and come out at Fimmvorduhals. An earthquake like this could indicate that the cap is breaking.

I’m a volcanology newbie, but have been in and out of research for the past year (also in and out of Iceland for the past three years) as I develop a new poetry manuscript that includes Icelandic volcanology. My primary work is as a poet and interdisciplinary artist (based in Canada), and I was fortunate to be in Reykjavík when the Fimmvörðuháls eruption began (actually attending a Peaches concert that I’ve since reviewed for the Reykjavík Grapevine). I’m now in southern France, and very thankful for this blog. I’m learning much by following discussion.

    The map you posted intrigues me greatly, and I have been wondering this morning (and searching online to no avail) if magma tube cartography exists. Any pointers would be greatly appreciated.

    Your most welcome, Angela, but no thanks neccessary. We all help out here! Somewhere, there is a graphic listing of all the quakes that shows a different picture then the one on MBL (which after all is a newspaper). From that, it would appear that the magma conduit runs almost straight up under the ~5.5 SW Básar location to a depth of approximately 1.5-2km, then veers off ENE towards the eruption site. I’ll see if I can find the link for you!

    @Henrik
    I also think that the schematics are somewhat different from reality. I would rather say there is a chamber-like formation between around 6-12km, and the ‘finger’ grown from there also has a different path (going straight upwards, then turning to east just below the surface).
    Though, i started looking into this only 3 weeks ago, so there are probably more experienced people in this area ;)

    Btw, what could be the scientific explanation of the difference between the Katla chamber and the Eyja ‘magma-matrix’ underground? Perhaps different EQ maps?

  777. #785 Chris
    April 7, 2010

    @viktor #782 These are most likely different lava supplies. The lava of Eyjafjallajökull has been described low in tatanium, while the lava of Katla has quite of lot of it.

  779. #787 Viktor
    April 7, 2010

    @Chris,
    Thanks, i agree with the fact that they are from two separate sources, the only thing bothering me is that they are shown with a different structure. Katla has a clear chamber on the schematics, while Eyja has some labyrinth, although the EQ maps rather show a more homogeneous chamber.

    I think this is interesting in order to understand how the eruption will continue:
    1. Either there is a significant amount of magma waiting in the hallway to erupt
    2. Or some small chunks of magma will come, but the majority of the remaining part will stay there and cool down quickly.

    I also recall some news back in this thread about the magma coming directly from the mantle and not from any chamber. Does anyone know what was the proof behind this claim?

    I just came across a new bit on Mbl, which contains an interview with world-fame icelandic volcanologist, Haraldur Sigurðsson. He states that in spite of the large eartquake(s) yesterday the state of the activity has NOT changed; rather he notes that the “old crater” (the 21 March fissure) has ceased erupting, and the second (31 March) fissure has one vigorously active vent – which by the way has built a nice little cone, that is now well visible in the new Fimmvörðuháls webcam (nice, this one).

    One one of the newer threads on this blog there has been a bit of discussion about the group of three people who possibly came to see the eruption yesterday, got lost in bad weather, and two of them died, a woman and a man; another woman survived. This, unfortunately, is something that we’ve seen on various occasions on Etna – the most recent and particularly tragic accident was in late-2008 – and we will see over and over again during volcanic eruptions. Volcanoes can be extremely hostile environments for a number of factors other than their eruptions, like weather conditions and rough terrain.

  782. #790 Jón Frímann
    April 7, 2010

    It has been confirmed that the original fissure has sealed up and now there is just one vent open. That would also explain why inflation has started again in Eyjafjallajökull, as this new vent cannot keep up with the inflow of magma into Eyjafjalljökull at the moment.

    This going to get interesting from now on.

    New information (mostly in Icelandic) at Nordvulk:

    http://www.jardvis.hi.is/page/jardvis_eyjogos

    This tells mostly who is doing what at the eruption site today, but also has a link to two pdf files. One (in English) gives the results of gas measurements taken by some of my colleagues of the INGV (Mike Burton, Giuseppe Salerno, and Alessandro La Spina) together with Icelandic colleagues. The emission of SO2 was about 3000 tons per day, which is similar to values we see at Etna during non-eruptive periods (during eruptive periods it can rise to more than 20,000 tons per day). The other pdf file shows a map of all known fissures and vents in the Eyjafjallajökull-Katla area.

    Have a close look at the Fimmvörðuhálsi cam. Look over the left shoulder of the scoria cone around the obvious active vent. Watch it for a while. Is anyone else seeing an occasional hint of fire fountains in that area? As if there was another vent *behind* the active vent…

    Question is, if I’m not seeing things, is that another portion of the active vent, the first vent reactivated, or a new vent?

  799. #807 Henrik
    April 7, 2010

    @Gina. The Valahnjúk camera gives a good view of the lava flow that has – finally after three weeks – come down the cliff! “Crtl” “+” ;)

  800. #808 Boris Behncke
    April 7, 2010

    @Fireman (@800) – that’s one of the vents on the 31 March (the second) fissure. This cam is looking straight along that fissure, and the cone of the first (20 March) fissure is seen standing at right. So the vent that does produce the occasional lava spray behind the main active cone is on the fissure that opened on 31 March.

    There’s something important I should remark on the seismic activity. Pleeeeeeaaaase folks, be careful jumping into wild speculations on what little you can see from the seismic activity. Volcano seismicity is terribly complex, and here on Etna, for example, we see an incredible variety of seismic signals, from volcanic tremor over long-period and very-long-period and all sorts of other signals (except for “tornillo” signals that seem to lack on basaltic volcanoes). And then, we also see enormous amounts of noise – wind, man-made, and all. Each tiny variation means something but you’d need to be a volcano seismology specialist to understand them. I would be very careful from looking at the signals in Iceland from a distance – they can mean everything and nothing from what we get on the internet. As a matter of fact, when trying to understand what certain seismic signals at Etna mean, I always ask a seismologist among our colleagues here – actually, in the control room in Catania, where all the data are coming in in real-time, it is mandatory that there is always a seismologist present, 24/7, in order to prevent misinterpretations of the seismic signals. The one seismic signal at Eyjafjallajökull that seemed pretty clear to me was prior to the eruption – that was a very typical and intense seismic swarm of the kind that we usually see before an eruption (not necessarily a big one, though – there is no proportional relationship between the intensity or energy release of a seismic swarm and the magnitude of the ensuing eruption).

    Finally, there’s no such thing as “due” in the world of volcanoes, at least not in the sense as we understand it. A volcano may behave completely differently from what would seem logical to us, and it does so always with good reasons, only that we don’t understand them. It’s like saying “Yellowstone is due” because its last overwhelmingly powerful eruption occurred so long ago. What we easily overlook is that Yellowstone has erupted many times since its last BIG cataclysm. Or Vesuvius .. between 1631 and 1944 it produced a moderate-to-large (but not Pompeii-size) eruption approximately once every 10-20 years. It has not erupted since 1944, so that’s now 66 years without eruption, and many people come to the misleading conclusion that a new eruption is overdue since at least 46 years. That’s human reasoning. If we look at Vesuvius’s eruption in AD 79 (the one that destroyed Pompeii and other Roman towns), we see that before that event the volcano had been quiescent for about 800 years. So what about that 10-20 year-interval?

    In any case, now the view from the new Fimmvörðuháls webcam becomes delightful.

    @820: it could also be the opposite: if volcano conduits are full or obstructed, magma won’t be able to flow and therefore generate tremors as easily as before. In this case we should also start seeing added ground inflation as internal volcano pressure rises and consequently also more earthquakes.

    There was a steam plum where you pointed out earlier. Is that actually the direction that the conduit runs underground to the eruption site?

  836. #844 Brian
    April 7, 2010

    Gordys, the point where the steam emanated from glows brightly from time to time on the Valahnjúk camera. I’ve been watching it since it got dark. If that is the end of a lava stream I can’t understand why we can’t see any of the path it would take from the cliff top. Not by glow or earlier by steaming.
    It’s also the location I think of one of the earlier small EQs.

  837. #845 Gordys

    I have not been able to notice it from the other cams but the one that Randall pointed out, looked like it was uphill from the current eruption site.

    Gordys yeah the one I saw was just to the right of the vent on the

I am glad you saw it too….sometimes this stuff plays tricks on you but I really thought I saw it.

  840. #848 Gordys
    April 7, 2010

    @Randall, that was the same thing that I was looking at..once you pointed it out. A small plume coming from a discrete location. I should have taken a screen shot. It must have been close to 3/4 of the way up the view. Now, which way is the camera pointed and which way does the conduit run? Could it be something else? Time will tell. Ah speculation…but speculation is kind of fun and makes one think. As long as it is kept in context.

    It’s hard for me to say what was up there. There was steam coming up from something though.

    I hope to see the current eruption site open up more so it can release some of the pressure in the system. That would be the best for the people of Iceland and the tourists…I know how stupid tourists can be. 8 pickups went through the ice up here this Spring, not to mention the wheelers and snowmobiles…most of it was because of stupidity.

    http://hraun.vedur.is/ja/arg/png/eyjafjallajokull_15d.png

  861. I was impressed with the axial image graphs released by Icelandic MET on the 31st. They plotted the quakes from 13 March through 24 March vertically as well as horizontally (using the highest magnitude tremours)… linking also that excellent article of Eyjaf quake propagation from earlier studies, that I had mentioned back on 10 March.

    I’ve taken their plots and repositioned them relative to one another to make dual-axis interpretation easier (plus links back to the original story and graphs) – see http://michaelbix.livejournal.com This also gives an idea about where the magma did some up-level exploration… which could be the basis for later breakthroughs.

  863. #871 Henrik
    April 11, 2010

    With the bad weather of the past three-four days, it’s hard to tell what, if anything, is going on. As Jón Friman says on a more recent topic, the harmonics seem to have dropped below the background (wind/weather?) noise on his geophone/seismometer. Then again, right now there’s a gap in the cloud and the Valahnjúk camera shows steam above both vent and lava flows. Whether this is due to an eruption or heavy rain is not immediately clear to a layman such as myself.

    We’ll have to wait and see – and have a look at the http://www.ruv.is and http://www.mbl.is newssites!

  864. #872 Diane
