A quick update on the ongoing activity at Eyjafjallajökull:

The activity at the volcano continues to be more explosive during the last few days than it was in the previous week, leading to more potential for airspace closures over Europe if the winds were to shift. Currently, the VAAC ash advisory only seems to suggest that even Spain may get a taste of the ash sometime tomorrow, but most of Europe will be OK. However, transatlantic routes to Europe could have problems as many flights will need to be routed significantly south to get around the ash. All of this has now lead for a push for satellites that can detect ash more effectively. Tourism in Iceland has seen a boom since the eruption started – one of the economic plusses in a story that has emphasized the minuses.

The latest Icelandic Met Office update for the volcano has the plume reaching 9km / 30,000 feet, which is one of the highest levels we’ve seen for this plume so far. Ash fall has become severe in some parts of Iceland, where even 65-70 km away from the vent “everything has turned black.”I haven’t been able to find much else about the “bulging” reported yesterday in the USA Today other than the IMO mentioning “Increased seismicity suggests that new material is intruding from deep below Eyjafjallajökull and latest GPS-observations suggest inflation. So far, GPS-signals are not large.” My guess is that the inflation isn’t significant, just noticeable on the installed GPS receivers. The composition of the lavas erupting from Eyjafjallajökull are squarely andesitic (well, at least the one sample analyzed so far) – and it does suggest that the current phase of the eruption is more silicic than the original fissure and the eruptions on the volcano in late April. This might suggest that the basaltic magma from depth is still effectively mixing with the more silicic (rhyolite) mush in the Eyjafjallajökull magmatic system.

I discovered the other day that a friend of mine from graduate school is in Iceland right now watching the eruption. Dr. Joe Licciardi is a professor at University of New Hampshire who studies subglacial volcanism (from the glacial side) so he headed out to check the processes in action. The two images in this post are from Joe (thanks!) showing the state of the Gígjökull glacier (in much worse shape than it was a week ago; above) and a shot of the air quality in southern Iceland (with the plume in the background; below). Lets just say I’m more than a little jealous of Joe right now …

    It seems the plume is reaching pretty high, according to USA Today!

    “A Boeing 757 flying nearby observed a black plume at 421,000 feet up heading towards the southeast.”

    The plume seems to have reached well into space. And all visible from a 757. Impressive…

    A shout out to Joe Liccardi, enjoy your adventure!
    @3 Bruce, the color probably reflects the ash content in the plume rather than the compositions. Volcanic glass (which makes up the ash) tends to have similar black-gray colors no matter the silica content, particularly small particles. Iron content plays a stronger coloring role in glass. Obsidian, or rhyolitic glass, can appear very similar to basaltic glass.
    Now the rocks (or crystallized lavas) are a different story. Low-silica magmas crystallize minerals with lower amounts of silica and higher amounts of iron and magnesium than intermediate and rhyolitic magmas. So as you you go from basalt to rhyolite you have increasing amounts of light colored minerals and decreasing amounts of dark mins. So the lavas become lighter in color.

    I was wondering if the strength and direction of the wind wouldn’t play a trick on us concerning plume heights. If you look at the plume from Þórólfsfell (from north) it looks very inclined towards left (east), but when you look from Hvolvöllur (from W) it points straight up, but deceivingly at a lower height. Does it make any sense?

    Hate to be nitpicky but …

    “Tourism in Iceland has seen a boom since the eruption started – one of the economic plusses in a story that has emphasized the minuses.”

    This was true when the eruption was going on in Fimmvörðuháls but after the flight bans in Europe things took a turn for the worse. A lot of tourists fear they’ll get stuck in Iceland for days. Also, many people appear to think that Iceland is a dangerous place to be, with thick ashfalls affecting the whole country etc. Hotel bookings are down 30-50% (compared to the same time period last year).

    The government has injected some money into the tourist industry’s PR campaigns. I guess if Eyja keeps up there’s always volcano tourism: http://elviajero.elpais.com/articulo/viajero/Volcanes/pueden/visitar/elppor/20100428elpepuvia_1/Tes

    Could it be that the camera vibrates sideways? Every once in a while – way too often, IMO – there’s blurring in the picture that looks quite bit like motion blur. At that distance, about 5.3 km, you don’t need much to make that happen.

    What I find curious, is that there seems to be little in the way of liquid discharge (on Thoro cam).

    Now, all that heat surely means there is a lot of melting going on, right? It can’t all disappear into steam, can it?

    So where is it?

  58. #58 Anna, Reykjavík

    @birdseye, good idea! Actually, after the bank collapse and economic crash in 2008 prices in Iceland have been very competitive, in fact lower than in most European countries. That’s why tourism has been booming lately and 2010 was supposed to be a record year.

Her left arm is raised to almost level, her right arm is akimbo, her left leg is a bit to the front, and she’s got white slippers. Veiled she is, and her dress is long.

    #57 @tj, I was wondering the same, then I thought, maybe the exit of further meltwater is prevented by rock, etc., and all meltwater now interacts with lava leading to the increasing plume.

    Looking at the gathering cloud of ash over the Atlantic, I’d say there will be major disruption over Ireland and Europe next week when the winds resume a more normal southwesterly / westerly direction.

    http://www.metoffice.gov.uk/aviation/vaac/data/VAG_1273232256.png

    On another note, we had a (very rare) earth tremor in the West of Ireland yesterday:

    http://www.met.ie/news/display.asp?ID=66

    I heard someone say on the radio that this might be connected with the Icelandic situation. Is this possible? I thought Ireland was well away from fault lines.

  63. #63 Kultsi, Askola, FI
    May 7, 2010

    #57 Indeed, very little discharge. The is no new lava coming in at the moment, that is why; the steaming is just water cooling down the lava that is already there. I think there is still melting going on upstream, but that hardly comes from contact with lava, just radiant heat. The water flows to the end of the lava flow, and as it cannot easily go any further, it does come into contact with the lava and happily boils away. Of course there is some overflow, but nothing like it has been in the previous days.

    From the Norwegian broadcasting today

    The volcano spews reach approximately 200 tons of material in seconds, yet it flows more from the depths of the earth.
    The result is that the material is stored inside the volcano. The researchers see this directly by the ground around the volcano rises. This increased pressure can lead to the eruption is more powerful than what we see now, “said the leader of the Northern volcanic center in Reykjavik, Rikke Pedersen.The explosive activity we’ve seen over the past day, is a direct result of pressure increase, but it is not enough to lower the pressure again.A heavy ash cloud extending southward from Iceland. The column of ash that comes out of the volcano is now up to almost nine kilometers altitude. It runs almost directly south from Iceland and will not land until it reaches Portugal. Wind direction is very lucky for Norway and Northern Europe, “said state meteorologist Håkon Melhuus. No matter what height the ashes sent up in, it is ruled out in the Atlantic Ocean off the mainland. It is a high pressure west of Iceland and a low pressure over Norway that dominates the weather, and ash cloud being pulled southward between these two weather systems.
    Wind conditions will remain so for many days to come,Air traffic to or from the United States is now being conducted south of the ash cloud. It causes delays.The outbreak is now different than it was in the middle of April. Then came the massive ash cloud from the contact between the floating stone and cold meltwater from the glacier. Now is not the lava in contact with water, and the explosive activity originating from the gas that comes with the stone from the deep.Two of our researchers was gas poisoning when they would take samples near the volcano, “says Rikke Pedersen. None of our will now be allowed to move near the volcano without gas masks.Most of the gas is CO2 and sulfur dioxide, but there are also other toxic gases that lie in the ground near the volcano.
    The gases are also mixed into the melt water coming from the volcano, making it toxic.When the pressure becomes smaller as the lava moves up inside the volcano, the gas expands explosively. The lava coming out now, contains more gas than before, says Rikke Pedersen. – But we are not sure whether the lava is different, we have people looking to find out now.hat is clear is that the gas does not lead to such powerful explosions that led to the water. It leads to the ash particles are larger than before.The ash particles are larger, leading to the fall faster, and that cloud not reach so far, “said Pedersen. – And I guess the only good news we have today, “she said.

    Dubliner, I am not sure about Ireland and the Iceland eruption causing a quake. One thing I do know is that given the right conditions, a large quake from quite a distance can trigger a fault that is likely ready to move anyway.

    Last year when Northern Sumatra had a 7.6 (if I remember right) quake, within an hour there was a swarm of small quakes at Mammoth Mt. in CA. It could have been triggered by the Sumatran quake, but there was really no way of knowing.

    So it can happen. In the case of Ireland, I would say it is just speculation on the part of who came up with that idea.

    I hope this answeres your question. I know Erik or Boris would be able to have much better input on it. A seizmologist would probably have a better idea because that is their focus.

    It’s cleared up a bit on the Hvolsvöllur cam and I see what appears to be a large amount of steam forming behind the ash column, at a somewhat lower level than the ash cloud. Is the steam from melting on the far side of the caldera, or is it coming out of the vent directly?

    Interesting plumbing system this volcano has; an apparently steady progress from basalt to andesite. Opposite of the usual sequence in subduction volcanos (silicic first then more mafic). Magma mixing? Most silicate melts are entirely miscible…under lab conditions. But field evidence suggests that separate batches of melt take a good while to mix completely, if they’re erupted before the process is complete there will be a streaky, blebby texture of the two original melts imperfectly mixed. Wonder if any evidence of mixing has been seen in hand sample of the eruption products yet?

    Second query: is there likely to be any health hazard from fluorine with this eruption? Hekla eruptions, and Laki 1783 have produced dangerous quantities of it, and they’re not too far away.

    BTW: Thanks to Bruce for answering my query on SO2 on another thread..by the time I returned to the site the discussions had moved on

    Today’s report from NORVOL http://www2.norvol.hi.is/page/ies_Eyjafjallajokull_eruption

    Eruption in Eyjafjallajökull – Status Report: 16:00 GMT, 07 May 2010
    Icelandic Meteorological Office and Institute of Earth Sciences, University of Iceland

    Compiled by: Sigurlaug Hjaltadóttir, Rikke Pedersen, Björn Oddsson, Ólafur Freyr Gíslason, Guðrún Larsen, Benedikt G. Ófeigsson, Matthew J. Roberts, Bergthóra S. Thorbjarnardóttir.

    Based on:
    IMO seismic monitoring; IES-IMO GPS monitoring; IMO hydrological data; IMO weather radar measurements, MERIS satellite image; reports from sent through the IMO web site, information from commercial flights.

    Eruption plume:
    Height (a.s.l.): 7 km according to IMO weather radar measurements at 1155h. Commercial flight heading towards Keflavík at 15:18h: 20,000- 25,000ft (7-7.6 km).
    Heading: Southeast
    Colour: Colour: Dark at the bottom, otherwise light gray.
    Tephra fallout: Considerable in Vík ashfall began at 21h last night; ashfall reaches to ~55-60 km from eruption site, midway through Mýrdalssandur.
    Lightning: No detections today over the eruption site.
    Noises: No reports

    Meltwater:
    During the last 24 hours there have been no flash floods from Gígjökull measured at Markarfljótsbrú. Electrical conductivity has been decreasing and daily fluctuations in discharge and water temperature have been observed. The electrical conductivity in Jökulsá á Sólheimasandi which has been traced to ash contamination from the glacier is still quite high. An increase in discharge has been observed in rivers in the area around Mýrdals- and Eyjafjallajökull due to higher ambient temperature.

    Conditions at eruption site:
    The ash plume is lower now than yesterday. The wind affects the plume and ashfall is less. The cinder cone continues to build up around the eruption vent in the ice cauldron. The lava flow to the north has been stagnant past two days.

    Seismic tremor:
    Tremor levels are low, comparable to yesterday and the period on 14 – 17 April.

    Earthquakes:
    Earthquakes are still being recorded at 5-13 km depth, but fewer than yesterday.

    GPS deformation:
    Measurements from around Eyjafjallajökull indicate no major net discplaceaments, suggesting a stabilization of the surface deformation since yesterday.

    Other remarks:
    Grainsize analysis of samples taken of ash that fell on May 3rd at 64 km distance from the eruption site shows that about 5 % of the ash is smaller than 10 micron (aerosols). This is a considerable decrease of fine particles compared to ash from April 15th (25% aerosols) sampled at a similar distance. The grain size analysis was carried out by Nýsköpunarmiðstöð Íslands.

    Overall assessment:
    Explosive activity seems to have decreased since yesterday. The ash plume does not rise as high into the air and is lighter in colour. Steam rises from the lava tongue under Gígjökull which is a sign that ice is melting in the tunnel, but to a much lesser degree than when the lava flow was at its peak. There are no signs that the eruption is ending.

    Subglacial volcanism! what a great subject, makes me want to go back to school.

    Eric, maybe you can arrange a Q&A session for Dr. Licciadi on your blog, like you have done before. I would like to know if the “split boulder” at the foot of the EJ glacier is actually the toe of an earlier subglacial lava flow. I can visually imagine a lava flow carving a channel down through the glacier, but then piling up at the bottom of the steep slope as is contact-cooled with the overlaying ice sheet. This would form a lava dam that would continue to inflate as fresh material entered it from higher up the slope. Eventually, it would cool and crack, allowing water erosion and frost ablation to form the big split we can see on the cameras, that until last week was the primary exit point for the melt water.

    Has the lava flow just restarted? There is more steam at the upper part of the trench and a new hot spot higher up, but not where I think the explosive plume should be.

    Help an amateur. Norway media seems to suggest that the eruption could get worse. Iceland experts say that the explosive activity is less. Tremors are down and EQ too. Is this the calm before the storm or is the volcano settling down?

    I think i’ve got the answer for the triangular purple area to the left of the tongue of the glacier- Thanks to everyone for thoughts and maps!!! (yeah, that’s a shout-out)

    On the fra-thorolfsfelli cam, to the left of giga appears to be a rocky spot, then another, smaller glacier tongue. it’s wide and the top, and seems to fall into a narrow canyon (as predicted by Gordon) I also think that Reynir Heiðberg Stefánsson got it right on the river outflow location. What confused the issue is that the map show no glacier over the drip zone, but it’s there (maybe packed up from the winter– it is a shallow area on the topo). So the gentle coloring would be meltwater in a kind of wash.

    “Old Engine Oil beer
    Harviestoun Brewery, UK

    A Scottish-style ale, Old Engine Oil has a dark color, almost like used engine oil and it is made by a former Ford worker, Ken Brooker.

    While the ale may look like old used oil, it definitely does not have an oily taste. It is very silky, like stout, with a tart citrus flavor and a hint of dark unsweetened chocolate. This beer would be a very good winter warmer or after-dinner brew.”

    What a remarkable volcano she is! Tremor is low, as low as it has been since the main eruption started. According to Jón’s helicorders, harmonic tremor too is low (unless he has changed their sensitivity). Other indicators – inflation, meltwater – do not point to any great activity. In spite of this, our Lady Eyja has put on one of her great displays and, as far as visible sustained activity at a high level is concerned, perhaps the most prominent.

    @Reynir132 – and sheep don’t like to be closed in tight, they get pneumonia easily if so, thus, a double problem. Maybe in Iceland it would be easier to move a flock from one place to another, but here,I think too much chance of spreading disease for one farmer to help another that way, even if clean pasture were available.Would be interested to know what efforts are being made to help heavily-ashed farmers with animals.

    @motsfo #135 I’m not sure it is. The view from Þórólfsfelli cam does look like the lake has reformed, but if you view the most recent Vodafone stills (or the cam if it works for you – doesn’t work for me right now) you can see in the close up that it’s not.

    e.g.

    http://picasaweb.google.com/102175391233488315229/EyjafjallajokullVolcano7thOfMay2010#5468613415320123330

    I think this is another one of those numerous examples we’ve had of the camera telling little fibs.

    I must say, the new cam at Þórólfsfell does have better brightness than the Voda cam, and shows up the moraines and other details much better. It’s much easier to get a sense of how that valley really looks.

    I am, however, still a little confused by the left-hand steam plume on Hvolsvell cam, as it doesn’t look like there’s enough steam coming from the lava in Gigjökull to create a plume as high as the one on Hvolsvell… but again, the camera is probably fibbing again. ;)

    Nature, a Fragment

    Nature! We are surrounded and embraced by her — powerless to leave
    her and powerless to enter her more deeply. Unaksed and without
    warning she sweeps us away in the round of her dance and dances on
    until we fall exhausted from her arms.

    She brings forth ever new forms: what is there, never was; what was,
    never will return. All is new, and yet forever old.

    We live within her, and are strangers to her. She speaks perpetually
    with us, and does not betray her secret. We work on her constantly,
    and yet have no power over her.

    All her effort seems bent toward individuality, and she cares nothing
    for individuals. She builds always, destroys always, and her workshop
    is beyond our reach.

    She lives in countless children, and the mother — where is she?
    She is the sole artist, creating extreme contrast out of the simplest
    material, the greatest perfection seemingly without effort, the most
    definite clarity always veiled with a touch of softness. Each of her
    works has its own being, each of her phenomenon its separate idea,
    and yet all create a single whole.

    She plays out a drama: we know not whether she herself sees it,
    and yet she plays it for us, we who stand in the corner….

    For those of you(such as myself), that are on the Gigjökull destruction watch, keep in mind, the viscosity of the lava that is now being erupted will not flow as well as did the lava erupted at the original eruption site at Fimmvörðuháls, or the first lava erupted at the present site. I am thinking that it will take much more volume of erupted material, and more time, before we see any lava at the bottom of the glacier…IF the eruption maintains it’s present state.

    @147 Now it makes a nice string but it did not just some five-ten years ago. The middle of Iceland has sprung into life in the recent years. Check e.g. http://hraun.vedur.is/ja/viku/2003/vika_01/index.html and tweak the url to get different years and weeks. There is data since about 1995.

    It looks like there is one main “fissure” along Eyjafjöll-Torfajökull-(Veidivötn)-Bardarbunga-Kistufell-Askja. They are almost exactly along a straight line. A parallel one is Katla-Grimsvötn-Kverkfjöll. Especially the Bardarbunga-Kistufell area is pertty active on the earthquake maps.

    It is a tad discomforting to have Eyjafjöll erupting at the other end of the ‘system’. These volcanoes have produced several large eruptions in just the recent centuries (e.g. Eldgja, Veidivötn, Lakagigar).

    @birdseyeUSA #134: I heard from friends, where the parents are sheep-farmers as well, that farmers actually don’t like to move their herds, because there are some cases of scrapie reported. And the south is so far unaffected. Sounds like choosing between pest and cholera.

    @kultsi#42: My guess would be ‘yes’. It’s easy to set up a web cam; it takes a lot more time and money to set up so that it’s nice and stable. It may be wind gusts making the camera vibrate.

    @Shelly, 155, I don’t think it’s very high, the camera from here http://eldgos.mila.is/eyjafjallajokull-fra-hvolsvelli/ is pretty far away and the plume doesn’t seem to be much higher than the mountain… My question now: is it just me, or is the ash coming down very fast after being expeled? Does this mean it’s very dense/heavy?

    I am geting fantastic picture of plume from Mulakot cam just now, and pairing it with the heat image camera at Thorolfsfelli which gives a great idea of the activity at the base of the plume.

  161. #161 Dasnowskier

    @161 – look at the 3td image from http://www.mulakot.net/myndavelar.html. It’s clearly not that high (it should be out off the image for 25-30k)

    @ Gordon – you can always type ALT+Prt_Scr and then crop the picture after pasting it into MSPaint. I use a program called MWSnap, which can focus on individual screen elements, which is handy.

    My guess is the ash column is 12-14,000 feet right now.

    Looks like a nice steady stream near 18-20,000 feet. Our “E” volcano is taking a brief break from her 35,000 feet plume explosions. With yesterday’s deep quakes, I am sure she has PLENTY more ash/steam and magma to throw our way.

    Yep.. pretty extreme case of strombolian activity….

    Is it even possible for such a silicic lava (61,5% SiO2, that’s quite something!) to form a lava flow, or are we witnessing the start of a dome-growth episode?

    On Hvol’s webcam, the plume is very high, guesstimate >8km high…(top of the frame)

  182. #183 Volcanophile
    May 7, 2010

    Judging by the height of the mountain, I guesstimate lava fountaining/splattering to go more than 1km up in the air, that’s very intense..
    I had no idea such a silicic lava could erupt in that way….

    Ordinary dacitic lava erupts at about 850-900°C, and is extremely viscous. Is a much hotter, but still dacitic magma in a range of viscosity comparable to low-Si basaltic andesite, something, that would be capable of erupting in a Strombolian way?

  183. #184 Robert Bordonaro Arlington, TX
    May 7, 2010

    The EVO cam cleared slightly, for a few frames, that ash cloud, though fairly visible was at the top of the screen, close to 20,000+ feet for the moment. Of course, EVO is shrouded once again.

    Is there an exact name for the type of volcano Ej is? Iceland is part of the mid Atlantic ridge. It seems to me that this is only the beginning of further spreading of the plates. The only question is how long before it really goes.

  186. #187 Volcanophile
    May 7, 2010

    I’ve never seen something like that… huge spattering, clots of lava probably dozens of metres wide based on eruptive vents size… that’s really impressive…

    I’ve come upon something that frightened me a bit… Last eruption was in fact quite similar, albeit on a much smaller scale…..

    http://www.volcano.si.edu/world/volcano.cfm?vnum=1702-02=

    Last eruption produced intermediate to silicic tephra for 2 years long… then as the eruption stopped, Katla went off big time.

    My guess (very unscientific) is that nothing will happen at Katla as soon as Eyjaf is still erupting. Then, as Eyjaf will start deflating when the magma chamber will be exhausted, the resulting seismic activity could well stir up Katla’s innards just enough to make it go.

    Think of Eyjaf as “Katla’s Indicator”….

  188. #189 Volcanophile
    May 7, 2010

    Based on what it did at the beginning of the eruption, it’s already way past VEI 3, and heading its way into VEI 4….

    At least 0.14 km3 of material has been erupted in the first days only… not counting what’s belching out now. That’s pretty repectable.

  196. #197 Jón Frímann
    May 7, 2010

    Currently the ash cloud only comes from one vent it seems. But I fear that a new vent might open up any time if the magma gets powerful enough inside the volcano. With new influx of magma that might well happen soon.

    When that happens, we are going to see a monster of a ash cloud. At least that is what I fear is going to happen.

  197. #198 Passerby
    May 7, 2010

    Quiet word to the IES folks: would be a good idea to fly recon to estimate ash-induced change in Mýrdalsjökull and Vatnajokull icecap surface albedo, to be matched against rise in meltwater Q data.

    Would also be nice to know how much the local water table is rising in response to Eyjaf meltwater infiltration (wrt pore pressure, particularly on the N-S axis running through Fimm).

    Shocking visual change in Gigjokull outlet glacier since I last looked in here a week ago.

    No, this is a deep push of magma, not surficial magma flow seeking a new path to surface.

    IES knows the clues/pattern by now.

  202. #203 Jón Frímann
    May 7, 2010

    @Passerby, That does not matter. A new swarm can start without warning. There also might not be a earthquake swarm in the case of a new vent opening up. But that is a wait and see type of thing. It cannot be predicted in any way.

    The current vent is getting smaller due to build-up of material around it. That can be noted by the drop in tremor plots I think, due to less flow to the current vent. Currently the GPS data show that there is little to none deflation going on in Eyjafjallajökull. Some inflation has happened, and with the deep earthquakes (~30km). This is a bad mixture for a erupting volcano in my opinion.

  203. #204 Renato I Silveira

    While darkness and fog stopped our “gazing at fireworks activity”, I went through the first posts on Eyjaföll (March,4). It’s funny to see how unpredictable those wonders of nature may be:
    (…)”This would also suggest that magma might be entering the upper echelons of Eyjafjallajökull’s magmatic system. UPDATE: It appears that the Icelandic Met Office doesn’t think this is leading to an eruption (Thanks to Orri with help on the translation).”

    #AndrewWH #232 Welcome to the conversation!

    Yes, there has been steam rising from that spot for a while now. There’s a lava flow from the crater down towards Gigjökull and hot meltwater too, both of which are producing steam. It’s much more easily seen on the timelapse videos, e.g. http://www.youtube.com/watch?v=BCPbx0psMiI

  236. #237 Mr. Moho
    May 8, 2010

    I have noticed three things in the last hour or so:

    - Some earthquakes occurred
    - From the FLIR camera the ash plume appears to have a higher temperature than usual (since the camera was installed).
    - Tremor activity is getting more “jumpy”

    Could these things be all connected? Likely yes in my opinion.

  237. #238 AndrewWH
    May 8, 2010

    @ Suw 235 Thanks for the welcome.

    Having checked the timelapse I can see it was then producing a much more vigorous plume. The steam seems to have died off somewhat since yesterday, though, and with the subtle changes in topography it made it look further down the slope than before.

  238. #239 PeakVT

    Could we get an update from the professionals as to the status of the eruption? Maybe a new thread? It seems like MET is awfully quiet this time. No wonder with the beating they took over their last ash warnings. I personally believe they were right in issuing what they did. I back them up completely and I think everybody here should as well. They need a giant pat on the back for having the balls to say what they feel is correct. I just hope they don’t stop now. From this, it looks like the ash is headed towards North America.

    I have seen this question asked here several times but do not recall an answer. Does anybody have access to the latest analysis of the toxic gases being released from this eruption? I am particularly interested in the amount of fluorine. If it doesn’t seem important then look at this.

    http://www.fluoridealert.org/fluorosis-india.htm

    Large parts of India suffer from this, as do other parts of the world. I believe their drinking water is being contaminated from living on top of the Deccan Traps and getting their drinking water from there. Anybody know more about this? There are other traps as well and I’m almost sure they have this problem as well.

    #293 – Thanks for the link. From what I see in this the ash and the meltwater are both toxic. I thought so but I guess this isn’t unusual for this type of eruption. The article also states that the finer the ash and the further away from the eruption site, the more concentrated it will be. Not good news at all as any concentration > 2 ppm is considered bad. How come all of the silence on this?

    Results
    Soluble fluoride on ash surface: mg F pr. kg ash (ppm).
    1. (pH 6.45) Fluoride 92 ppm (Leached in the laboratory. Fluoride and pH of leachate measured in the laboratory).
    2. (pH 5.66) Fluoride 112 ppm (Fluoride and pH measured in meltwaer).

    Doc-So far there have only been analysis of the water/soils and that goes all the way back to April 2 so its out of date. There are high levels of chromium, flourides, obviously acids.

    There are also indications of Cesium in the samplings.

    Problem with air samplings is that this isnt rocket science, but you might need one to get a sample or two. Sounding rockets were used in the past to get the real information because its mostly evolving as it comes out of the hole. Compounds of this and that, lots of oxides, pure minerals and metals. Primordial base type of concepts. I have always found it interesting that around volcanoes that so many new species develop. But for now the EU says the air is safe… Like there was something that could be done about it.

    My only question about the flouride, assuming it becomes a large enough problem…what exactly should be done? It would be in the water, food everywhere. Wearing a mask would make no real difference. On a local scale there are solutions. On a Europe or larger scale…400 million or so people cannot move away, stop eating, drinking. Although I suppose stop breathing is the ultimate option.

    I think humans have forgotten just how intertwined we are with nature. At least in western/developed countries. To dredge up some vague medieval latin memory from the plague times.

    My laws of physics awareness is really not what it ought to be.

    Somehow I’d imagined that the lava would eventually emerge from under Gígjökull. But somebody pointed out to me that there’s no way lava will flow in an ice tunnel. The melting point is really high (of course) and it doesn’t actually take much water or ice to halt or slow down the progress of a lava flow.

    For the lava to get to Markarfljót it will have to cut a wide canal all the way. It’s extremely unlikely that will happen, seems to me.

    PS Apparently lava sometimes flows OVER glacial ice (happens very rarely though). In those instances there’s a thick insulating tephra layer underneath.

    I don’t mean to seem negative or anything but things are the way they are and as a parent I have to see the world for what it is. I find it very difficult to explain this to my kids. Not Ej or anything like that, my 7 yo thinks this is the coolest thing that has ever happened. The problem I have is that there are good people out there that truly care about humanity and have the best of intentions. They are suppressed everywhere I look, or are killed if they can’t be silenced.

    We as a people are in for a lot of trouble. It can be seen everywhere. Anyone with eyes, ears, and a mind can figure it out for themselves. We waste so much money and care so little for each other that a massive earth changing event may be the best way out of it. It’s really sad to think that way. Bring it on baby!

    It’s sickening to see science manipulated for the sake of saving a few dollars.

    Whatever, I’m going to stoke up the grill and hoist a few beers, and keep an eye on the webcams. At least if I die from Ej I will know the truth.

    @343: One needs a reality filter to sort the wheat (positive qualities of people from local to global scale) from the negativity chaf that is constantly peddled as ‘news’.

    Sure, money is wasted on war and ineffectual fight against poverty and disease (where corruption takes advantage of liberal kindness of others), but with the exception of bungled financial mismanagement debacle (credit and derivatives markets) from which we are presently emerging, our world is in not nearly as bad a shape as some would have you believe.

    Do not put your hopes for magical cures in catastrophic events to change the ways of Man, for the disruption natural disasters cause is likely to have a damaging domino-effect due to global interconnectivity that is novel to this time. Instead, I advise seeing the enormous problem-solving capacity that this interconnectivity brings with it as a dividend.

    Eyjaf is neither a climate nor human health changing eruption type. That requires a much larger, stratospheric (giant plinian) eruption. Even Katla is unlikely to produce such an event.

    Change is coming, but it will not be catalyzed by natural disaster, but rather from dwindling and scarce natural resources and population pressure. It will challenge us to reinvent manufacturing, will change our thinking of consumptive lifestyle and force consideration of human disruption of natural biogeochemical cycles of carbon, nitrogen, sulfur, iron and other minerals that has dominated the planetary ecosystem for several billion years.

    When one door closes, another will always open – if we recognize that opportunity naturally arises from adversity and need.

    Very strange atmospherics above Eyjafjallajökull visible on the Hvolsvöllur camera (19.40GMT). Three distinct strata visible, the bottom one undulating at ~1,800-2,000m, the other a mor straight line at the top left rising from ~4,000m at left edge to ~4,800m top edge just right of center. The latter delineated by a bright, thin, white streak of cloud. All three strata with distinctly differing visibilities. Any meteorologist online who can explain this?

    Suw (#240), very illuminative. Thank you!

    Lena (#228), Helen Leggatt (#229) – Boris (Dr Boris Behncke of the INGV Etna Observatory, Catania) told us several weeks ago that there were signs that Etna was waking up and that a new eruption cycle MIGHT commence on a timescale of weeks to six months. While Dr Behncke’s word is good enough for me, I think a better sign is that for the past week or so he, unfortunately for us, has had little time to post here and explains it with “work”. Of course there may be nothing in it, but as he asked us “webcamoholics” what we were going to do as Etna had ten webcams trained on her, I think it’s an excellent idea to acquaint ourselves with Etna before she erupts.

    Yes it is heavy but the logical conclusion seems to lead to the suggestion that our civil society as well as the concept of civilization itself is failing, will always fail, and is not worth the effort. As with freedom, discovery grows best when it comes from within. Understanding what is wrong with our respective unions should be asked by each of us. The answers should be made available not suppressed. Free thought should be as inalienable as free speech. See that happening anymore?

    The bullshit has been here for a long time but not forever. In the old world there were kingdoms and guess who had all the land and money. Same shit today, we just call them centralized banks. My problem started before I was born with the FRA.

    These eruptions didn’t even wake certain people up. They send some lackey up on a few test flights and declare it safe to fly knowing there is no way to tell until you fly straight into the shit. For money. Sure being delayed in Europe is an inconvenience but so is the bottom of the Atlantic. MET most likely saved lives when it acted accordingly to the situation.

    Assessment – 08 May 2010 18:30

    The eruption is still in an explosive phase. The tephra- and splatter cone continues to build up and is now reaching the rim of the ice edge around the crater. The plume doesn’t rise vertically from the crater, but bends SE-wards due to wind; measured at around 5 km hight this morning.

    Watching the antics on the Þórólfsfelli cam, I noticed (and grabbed shots of) some interesting activity in the background. Do we know for sure how many vents are supposed to be active here?

    There’s one obvious vent with continuous more or less vigorous activity, but I noticed a brief dark plume from what was clearly a second vent, with clear sky between it and the main plume. See: http://www.corestore.org/2vents.jpg

    New vent? Old vent reactivated?

    I have also been transfixed by the cams and your comments, why is this particular volcano so terrifying and fascinating!
    It seems that here in north west england that we keep getting light ash in the air, several people have mentioned that when they go out the air smells dry and makes ur throat dry, and my 3 dogs end up sneezing after sniffing about in the fields.
    Oh and whoever was wondering about the blue light apparantly its gas being given off by the magma.
    Has anyone heard anything about the two scientists who were overcome by fumes trying to collect samples?
    I’ve had a strange feeling of forboding for months now, like theres a storm coming….or maybe humanity is going to get a large object lesson soon. I wonder if EJ is the start of that lesson.
    Oh and has anyone noticed how flipping cold it is this year, the wind outside feels like march not may, I wonder if the fine ash circulating the northern hemisphere is blocking out some sunlight.

    It has become apparent that meltwater/lahar from the eruption has declined over the last few days, and at the same time lava flow and output slowed considerably since the eruption reverted from basaltic to andesitic magma and entered its second explosive stage. I though it worth posting a link to the original lahar at the beginning of the first explosive phase of eruption for people to be able to compare and contrast to… http://www.youtube.com/watch?v=9sryalI57oo

  393. #396 Henrik, Swe
    May 8, 2010

    What is erupting? I can’t help but ask the question as the maths simply doesn’t add up for me. The eruption started on April 15th, so this is the 24th day. The eruption rate, tephra and lava flow, was 300 m3 s-1 during the first 72 hours and has not been reported to be below 20 m3 s-1. With an official figure of 140 million m3 of tephra for the first 72 hours (=70-80 million m3 compacted magma), the total must now stand in excess of 200 million m3 of magma.

    If we assume that the primitive magma erupted at Fimvörduhals came more or less directly from the mantle and that there was a reservoir of rhyolitic magma below Eyjafjöll, the chemical composition hints that at best, the mix is 2 parts new + 1 part old magma. This would require a magma reservoir of at least 70 million m3 of very rhyolitic magma just to explain the eruption to date.

    Now, the inflation was reported as being 6 cm over an area of, very generous estimate, ~500 square kilometers (more likely 250-300). This gives a total of ~30 million cubic meters. It’s not enough by at least a factor of 2½ times.

    As far as I understand it, either Eyjafjöll volcano must be credited with a much larger magma chamber or the magma thought to come from the mantle must be of a very different composition from the magma that erupted first at Fimvörduhals.

    Could someone with a far better understanding of it please explain – what exactly is it that accounts for the observed composition and amounts?

  394. #397 Suw
    May 8, 2010

    @fireman I wonder if your photo has captured a short pause in the plume. She was quite bursty a while ago, looking rather like an outsized steam engine that was huffing and puffing. If she briefly ‘held her breath’, then the resumed plume would look to be separate from the main plume, just as your photo shows.

    Or there may be another explanation. ;)

  395. #398 Jón Frímann
    May 8, 2010

    @Fireman, Yes. That are them! :) I do not know at the moment if there has been a new vent. But it might already have happened. It has done so once before already.

    The reason for new vent to open up is the fact the current one is getting clogged up with material from the eruption.

    I’ve been talking to my husband tonight about some of the data that the IMO is producing, which I think we could probably do more with if given the time. Does anyone have links to recent historic EQ data, for example? I.e. not just the last 48 hours? I’ve had a look on the IMO site and it’s not obvious if they have an archive of the data publicly available.

    @ Suw 397: this was definitely a second and distinct plume; I watched it form as I grabbed the shot. The main plume was going steadily and non-stop from the same place it has been for weeks. The new plume had clear sky between it and the main plume, appeared very much darker – almost solid black – and appeared from a quite different place – at a guess at least 300m away. The photo shows the relationship quite well.

    The posting of a Goethe poem the other day got me thinking about other OTT descriptions and sent me up to my loft. William McGonagall in the 19thc was perhaps Scotland’s best “bad” poet ever.This is an excerpt from “Greenland’s Icy Mountains” which feels rather appropriate…

    Greenland’s icy mountains are fascinating and grand,
    And wondrously created by the Almighty’s command;
    And the works of the Almighty there’s few can understand;
    Who knows butit might be part of fairyland.

    Because there are churches of ice, and houses glittering like glass,
    And for scenic grandeur there’s nothing it can surpass,
    Besides there’s monuments and spires, also ruins,
    Which serve for a safe retreat from the wild bruins.

    And there’s icy crags and precipices, also beautiful waterfalls,
    And as the stranger gazes thereon, his heart it appals
    With a mixture of wonder, fear and delight,
    Till at last he exclaims, Oh! what a wonderful sight!

    The icy mountains they’re higher than a brig’s topmast,
    And the stranger in amazement stands aghast
    As he beholds the water flowing off the melted ice
    Adown the mountain sides, that he cries out, Oh! how nice!

    Such sights are those truly magnificent to be seen,
    Only that the mountain tops are white instead of green,
    And rents andcaverns in them, the same as on a rugged mountain side,
    And suitable placesw, in my opinion, for mermaids to reside.

    Sometimes these icy mountains suddenly topple o’er
    With a wild and rumbling hollow-startling roar;
    And new peaks and cliffsrise up out of the sea,
    While great cataracts of uplifted brine pour down furiously.

    And those that witness such an awful sight
    Can gaze thereonin solems silence and delight,
    And the most Godfearless man that hath this region trod
    Would be forced to recognize the power and majesty of God.
    ——

    @Fireman #414 Interesting. Which cam was that on? Hopefully one of the timelapses will pick it up. Did you manage to gut a larger screenshot than the one you posted?

    @Passerby #411 It’s a good idea to have a time-lapse archive. I’ll see what I can do about gathering all that together when I have a moment. If you (or anyone else) would like to help our by gathering links, that’d be fab.

    @Suw 421: it was on the Þórólfsfelli cam; my screen cap shows it well, with the ‘normal’ plume side by side for comparison:

    http://www.corestore.org/2vents.jpg

    That black plume is nowhere near the origin of the main plume! You can clearly see the shadow it casts, and when it emerged (but before I was able to grab the screen cap) there was even more clear blue sky between it and the main plume.

    I’ve looked at the vodaphone cam and not seen it captured there. It seems to have been a one-off at this stage, but I’d still like to know where it came from!

    @Suw 402. re archived EQ data.
    Socuel has archived validated EQ data back several months; contact him here:
    http://islande2010.mbnet.fr/2010/03/eyjafjallajokull-levolution-des-dernieres-heures/

    Korf’s 3D map for two days’ activity, corresponding to two large oscillations in EQ rate is here:
    http://666kb.com/i/bhjjgvgx4bayjzvvo.gif

    What would be ideal is a 3D display like Korf’s but with EQs colour coded for magnitude and interactive in so far as user can select period of EQs displayed.

    Do hope Henrik, Bruce, Passerby, MichaelC-b will add their ideas and support.

    There were unusual, possible unique, oscillations in EQ rate during the first 3 weeks of March (and maybe earlier). There could be real science to come out of that data!!

    @Fireman #423 I wonder if Mila are archiving the stream anywhere, or if it’s just evaporating into the ether. It would be interesting to be able to replay that section of video to see if there’s any more detail can be gleaned.

    If there’s no camera-telling-fibs trickery going on (god knows i’ve been fooled!) then it can only be a new vent clearing its throat. I went through the Voda stills, but didn’t find it either.

    This actually raises the question that has been nagging at me for weeks, pretty much since this began, and that’s whether the streams are being archived anywhere. (I know Voda is archiving stills to Picassa, but it still misses a lot out.) It might seem really excessive, but it’s only after an event like this where more clarity is needed that one realises the value of archives.

    @Peter #427 Thanks, I’ll go and have a look, and see what I can find. :D I’m not sure I can manage actual science, but I’ll certainly have a go at something that pretends to be interesting. ;) Well, I’ll have a go once I’ve hit the Deadline From Hell, that is.

The delay is similar on the FLIR site http://www.flir.com/thermography/eurasia/se/data/?id=30533. Thing is: there is a LOT of steam coming in the last half our or so, and I think this is what blocks the image. Otherwise, looking on Mila site you could think the eruption stoped, but it is actually at its peak for today at least. Or I may be wrong… :)

    May 8, 2010

    >Had we then had a real reason to be worried??

    Depends on how long and if we had other (seismic/tremor and GPS-inflation) indicators of deeper magma movement.

    Hopefully, IES is thinking collaborative thoughts with US and European geology counterparts for funding help, with an eye to updating pre-eruption estimates of glacier mass balance for Eyjaf. We also need to estimate Eyjaf’s ash deposit induced albedo (solar insolation reflection) change is affecting Katla’s icecap.

    Understanding temporal connection between Katla and Eyjaf coupled eruptions may rest on estimating the rate of meltwater percolation into the HIGHLY POROUS flood plains to the north and west, consequent temporal pore pressure flux, and it’s action in 3-D on stress-strain accumulation in the delicate, force-constrained ridge between these two volcanoes during historic maritime warm climate periods.

    Watch for increased hydrothermal activity north and south on this vector.

    I was the one sans hair by the way :-)

    Regrettably the volcano wasn’t very active – or perhaps we just didn’t wait until it was properly dark. At any rate I don’t think I got any good shots of the eruption – but I did catch a couple of that pickup crossing the “Jökulfall” (the outflow from Gígjökull).

    Just to illustrate how enormous an effect the eruption is having on aviation – since last night the bulk of trans-Atlantic flights are passing north of Iceland – there’s an impenetrable ash barrier extending south towards Spain.

    At work yesterday I saw a flight plan from Dublin to Chicago – northeast to hit the Arctic Circle just west of Norway, then west until well past the ash cloud (and Iceland) before turning southwest towards Chicago.

    May 9, 2010

    #502 @Passerby, I think Puyehue-Cordon Caulle is also a good example of an eruption triggered by a large earthquake (as it erupted short after Chilean earthquake in 1960) isn’t it? Is there a relation of this event in Iceland with the increased seismicity around the world? – (if it’s true there is such an increase) Should we worry about Tambora being so near the last Sumbawa-Region earthquakes, or there are specific characteristics EQs should have to behave that way?

    Henrik, Swe careful those inconvenient questions about the Eyjafjöll magma/magma chamber will get you into trouble….for down that path lies bottomless perdition;)

    Frito Lay that SO2 increase means that there has been a lot of mafic magma added to what has over time become a more increasingly silica rich mix. The question is where did all that silica rich magma come from? Also what will the mixing of a more primitive mafic and a more silica rich magma lead to? Anyone want to venture a guess?

    Weather’s supposed to be good today, so I hope the Þórólfsfell camera issues get cleared up. Hvolsvöllur and Vodafone are up.

    Steam activity is up a LOT from anything I saw yesterday at the front of the cut in the glacier. And there appears to be a glow. The lava never made it that far did it? And it likely couldn’t have overnight without some drastic change in composition resulting in the lower viscosity, right?

  512. #516 Passerby
    May 9, 2010

    Thick haze, change in volcanic effuvia chemistry (noted earlier in this blog thread).

    @ Renato: Chile SSZ (Puyehue-Cordon Caulle) volcanic activity is an example of icecap recession-related events over the past 12KY, with increasing silica content over time as rebound is associated with differences in chemistry due to crustal melt origin.

    Iceland went through a similar pattern of shield volcano activity with post glacial rebound (3 distinct periods, past 12KY).

    I’m guessing you’re referring to all that steaming at the front of the channel carved into the glacier? I noticed that too (# 513). The lava is supposedly still much higher up the slope, but if so, where is all the heat coming from to make that plume? And I’m also curious where the water is going. It’s unlikely to all be being converted to steam, yet runoff has been practically nothing.

  528. #532 Renato I Silveira

    # 529 @Ragutis, I was just wondering about the same. Water (and lava) must be blocked. Maybe will soon be seeing a waterfall sprouting there somewhere.

    morning everyone!
    @Peter, thanks for that Tahoe paper. I know a seismologist teaching in Northern California so with a bit of luck, I might at least be able to get some datasets via him. Cross your fingers! (He’s been pretty busy later with all the seismic activity in California).

    I might actually email the GNS people in New Zealand as there have been numerous swarms in the Taupo Volcanic Zone and the GNS people are usually very forthcoming. They might have something to add.

    I sorely wish I had time to do a few things:
    a) learn how to prepare an animated 3d sequence of the activity and generate one (hint hint for anyone still interested in doing this ;-) As mentioned above socuel has the data.)
    b) plot the oscillations in the GPS readings against the wave form in seismic activity to see what, if any, correlation there is.

    Failing that, it would be great if anyone with more time on their hands and expertise (not difficult, that one, as I have none) could do this. What would be exciting is, if once the graphic models are in place, we could feed data from Tahoe or other swarms into them to see what comes out.. ok so dreams are free. But it would certainly be fascinating.

    @Helen 518 which paper? I could get my family to send it to me.

    Yeah, that’s what’s weird. The last few reports had the lava stuck way upslope. But there seems to be a lot of energy down at that last “wall” of ice before the drop off.

    Sure, but the energy seems to have increased quite a bit over the last couple of days. The lava flow downslope is supposedly pretty static, isn’t it? Where’s it finding new ice to melt? I would have to guess that something changed with the lava flow overnight. It’s increased or found a breach in it’s dam or something.

    “The lava flow downslope is supposedly pretty static, isn’t it? Where’s it finding new ice to melt?”
    Or maybe it just turned ou to be more mafic. Thie eruption has shown regular ups and downs of effusive to explosive activity. It still can be blocked, but, since it is hotter, it generates more steam. What do you think?

  541. #545 chasm
    May 9, 2010

    the water or ice in contact with hot rocks will produce hot steam which expands as it rises. A hot water lake will not produce expanding steam only a mist that slowly rises and is not very persistent.(ie the front end of the steam production and the small plume below the rim.

  542. #546 Ragutis
    May 9, 2010

    It just came to mind that if the wind has shifted and will be stable, Mila might be able to get someone up to have a gander at the Valahnúkur cam.

    @Birgit, it’s definitely pretty crowded. But the forecast on those charts I’ve posted in #549 seem to show a rather different picture for the next days.
    I don’t know how airlines will respond to that. I’m glad none of my relatives are going to fly through the Atlantic, because I’ve already had plenty of distress during the Air France crash flying from Rio to Paris, where a good friend and partner just vanished in the bottom of the ocean. But maybe I am not very good at chart interpretation. Hope so.

    @Birgit #551 FlightRadar24.com doesn’t include French airspace, I presume because they can’t get the data. We therefore have to completely ignore the big black hole in flights over France on that site.

    @Renato #552 I too am wondering how the airlines are going to respond to the ash advisory today. I am supposed to be ahving a house guest fly in from Switzerland (doesn’t look likely) and my husband fly back from Budapest (looks like he should be ok but probably diverted northeast of the cloud). But I don’t know if that big red zone is the basis of the ‘no-fly’ or if Eurocontrol makes decisions based on other factors too.

    #554 @Suw, they do, indeed, but how reliable are those factors? I don’t want to alarm you, but they have already raised the level of tolerance for ash concentration, saying it “should be a safe level” – but who can precise exactly where a bunch of invisible particles should be concentrated in a given moment and location?

  558. #562 Suw
    May 9, 2010

    @Renato #556 Oh, I’m already a bit alarmed, especially seeing that the current Aviation Code Red zone appears to be being completely ignored, if FlightRadar24 is anything to go by (which it, of course, may not be). My husband and fly more than I like, mainly to conferences and to give training, and I’ve become very, very, unhappy with it. I’m very conservative when it comes to air safety, and the stunts that the airlines have pulled have not made me feel particularly confident in their ability to assess risk.

    Thankfully, come the end of the summer with both change jobs and will be flying a lot less. That makes me very happy.

    May 9, 2010

    And now a bit of black humor: My friend is supposed to fly with his family to Paris next week. He said he would send his mother in law in advance to see if the effects of the ash cloud are truly effective. Worst case scenario, he says, she will get there safe and sound – and the trip will proceed as planned. (That was mean!)

    Flew out of EWR on a flt to DUS on wed 04.28 with a bit of thought on the doings of ash cloud. Funny thing was about 200-400 mi. SSE of Iceland (using flight map on plane) there was a strong aroma in the plane. Best description of the smell was roasted garlic. This lasted about 30 or so minutes. The meal had been served about an hour and a half earlier so doubt this would account for it. When we returned last night(MUC) we were told that due to conditions associated with the ash we would divert from our normal route. The flt. path took us over Bergen, Norway to the NW about 400 mi., then due W till Greenland then SW along the coast back to EWR. No garlic

    I’ve been staring at this http://666kb.com/i/bhjjgvgx4bayjzvvo.gif picture, and some things come to mind.

    1) It’s slanting, from top to bottom, NNW – SSE
    2) There is something at 5-6 km level and then below 8 km going on
    3) A far larger color range would make it easier to grasp the 3D picture
    4) That picture really needs a (3D) map in it, if not for anything else, at least to assess how many of the low EQs might be stress release from the weight of the mountain on top
    5) Would a grid of closer-positioned observation stations in tight time synch (like GPS), observing all anomalies in shock travel times, help in building a picture of the underlying structures. Micro-scale seismology. Don’t the oil prospectors use something like this, only they use explosives to get the shockwave.
    6) Better imaging of things is a must; in this age of amazing computer power it should not be impossible to build a model that the viewer can rotate to get a view from any direction

    With Ejya just taking a little nap, I would like to say hello and thank you for this great Blog where I’m learning lots and intensely enjoying every post – whether it’s geological theory or poetry. I’m another volcano cam addict based in Austria (waves to Birgit) who’s getting funny looks from her family because she can’t take her eyes off the spectacular beauty of this volcano. I’ve always loved Iceland (also the music of Sigur Ros which goes together very well with volcanoes) and I’d love to visit the country one day.

    Sulfides. Interesting that you could smell it so clearly in the plane.

    @Kultsi, geologists use a validated subsurface model to estimate location, correct/reposition and verify EQs. In their updates, IMO issues the closest approximation to a 3-D rendering with depth/lat-long visuals in 2-D (two sides of the 3-D cube).

    Hollsvellör is about 3-4 times the distance from the eruption site as vodafone is it is perspective mostly for voda to see the top it would have to be tilted so high nothing would be seen on the ground.
    and even then i don’t think the top could be seen for all the plume in the way

    @Passerby

    I know they do, even automated ones – for the seismologists’ needs; I see results of those daily on the USGS site.

    What I thought was that there might be more data to be gleaned from the very small EQs almost always present at volcanic areas, not that it would change anything, the volcano would blow its top anyway and when it decides.

    Apparently, the current models are not much, as we have no idea about the actual amount of the magma about to emerge; no idea about the type of the eruption in advance, or which way it’s going to turn; not even when an eruption is going to happen.

    I admit that the eruptions don’t happen often in any one place, but it seems prudent to push more money into research and contingency planning, because even a small fraction of the losses taken by air traffic halt – and not only the carriers – could go a long way there.

    Darn, this is getting expensive – another 2c.

    Update on activityEruption in Eyjafjallajökull, Iceland
    Assessment – 09 May 2010 15:00
    The eruption plume is grey or light gray and mostly 4-5 km in hight (14-17,000 ft) but sometimes shoots up to 6 km (20,000 ft). It is heading southeast but low level winds are easterly.

    Tephra fallout is further west now. Black ashfall was detected at Skógar this morning and also at Þorvaldseyri, just south of the eruption site.

    Noise was reported from Vestmannaeyjar-islands (35-40 km southwest of erutpion), Vatnsdalur (190-200 km to the north), and Borgarfjörður (~150 km to the northwest).

    Deflation of the Eyjafjallajökull volcano contiues. Compared to last seven days, the output from the volcano has been slowly decreasing but the activity has been pulsating and further changes in overall activity can be expected. Presently there are no indications that the eruption is about to end.

    The above is based on a status report issued collectively by the Icelandic Meteorological Office and the Institute of Earth Sciences at 12:00 today.

    Ash is NOT completely HARMLESS. It is an abrasive substance the melts inside the jet engine and tears up the turbine blades and can easily shut down jet engines. Several damage reports were floating around in April, from the military aircraft flying through the ash, and a civilian airliner experiencing engine damage. The airlines are playing with FIRE and PEOPLE’S LIVES, in the name of “profit”. God forbid there is an unfortunate accident, that will cost lives and hundreds of millions of dollars and SHUT DOWN a good part of European airspace temporarily.

    @Kultsi, the only way I know of forecasting potential magma rise is by pattern recognition of repositioned/validated EQ swarms (as happened in last 24 hours). Clearly, magma is continuing to rise from depths > 10 Km, and appears consistent with decreased icecap loading, increased pore pressure action in the top 200-300 m subglacial depth and in the flood plains below Eyjaf.

    Also note that IMO mentioned (yesterday) that the meltwater had apparently changed paths from N to E, indicating new magma movement direction, possibly consistent with the observed second vent reported by Fireman yesterday. Unless we have an recon flight photo showing the second vent location, we have no way of knowing if it’s a pre-existing or new vent, or that the new vent is the source of the magma flow path change.

    Yesterday there where two earthquakes with the depth of 30.6km and 30.2km. This is the deepest earthquakes that I have seen so far happen in Eyjafjallajökull. Both earthquakes where small.

    GPS data from THEY show that the inflation has once started in Eyjafjallajökull. This has happened mostly on the north-south direction of the mountain. Currently there is no deflation or inflation in east-west direction in Eyjafjallajökull.

    http://www.metoffice.gov.uk/aviation/vaac/data/VAG_1273403985.png

    The South of Spain continues clear of this. Aircraft reroutes are now carrying them north of Iceland, adding an hour or so or South to the African states or South Spain. Even so Algeciras has yet to be closed due to this.

    The airlines are going to have to come up with something soon. The SDR’s (Service Difficulty Reports) have jumped across the board for all of the trans-atlantic hoppers and quite a bit for the regionals. Conductive ash in actuator boxes, acidic in air systems. The biggest write ups right now are for air systems (big surprise) but engine abrasion is being noted. Not terribly so just jet but one blade on a Trent costs about 10,000 bucks and more than a lot of money to replace.

    A lot of engine joint point erosion and corrosion is also being noted. They can blend it out and balance it for the better part, but if this doesnt stop soon they will simply because of the economics of being in business.

    I never knew that there was a long-recognized connection between seismic activity and detectable electric and magnetic fluctuations.

    http://repository.dl.itc.u-tokyo.ac.jp/dspace/bitstream/2261/25207/1/tssj015012.pdf

    My interest was raised when I came across http://volcanism.wordpress.com/ where there is a report that

    “…in the month of December, 1821, and which in some cases was accompanied with an agitation of the magnetic needle, brought many persons to conjecture that some tremendous convulsion of nature must have visited some part of the globe. This conjecture has at last been verified by a volcanic eruption of the old volcano of Eyafjeld Jokkul, which has been in a quiet state since the year 1612.”

    Everywhere these days we read of seismometer readings, etc., but are electrical and magnetic forces monitored in relation to the present volcanic activity in Iceland? If so, are they to be viewed online anywhere?

    Another interesting paper I hope to finish reading shortly:

    http://www.geomag.bgs.ac.uk/earthmag.html

    and in Wikipedia I found that the term Geomagnetic Jerk can be used:

    #616 Randolph do ypu have a source for the SDR’s? I’ve long suspected that what we will see is no major incident, hopefully, but a general degrading of the european airline hardware, which is going to cost a lot of money down the line. With $100.00 oil a tipping point for the industry ($75.00+ at the moment) this is just another nail in the industry’s coffin.

    The airlines must balance nonessential air traffic flow against ash-induced damage (surface abrasion, oxidation and air-intake/instrument systems clogging).

    My suggestion still stands: offer incentives for nonessential flight cancellation or rebooking to move elective air travel to a later, safer date or choose alternate locations outside of Europe. Even better, work out deals to reroute regional hopper traffic to ground transportation within Europe.

    As much as 1/2 of the air travel passenger load is nonessential (nonbusiness, elective). After the first major mishap, fewer passengers will be inclined towards accepting flight risk.

CA is getting a lot of them along the border and also they tend to head up north and turn toward the NE. According to John McPhee, the Gulf of CA is eventually going to meet with the Salton Sea again and the water will go up into NV. That will take a long, long, long time. There is a tale that talks about a Spanish ship that is supposed to be buried in the desert because at that time, the water from the Gulf of CA was up as far as the Salton Sea. How it got separated in the mean time, I have no idea.

What would the response time be to get a load of inflatable rafts and rescuers to drop by helicopter, if needed?

    Yes, I’m aware how few successful aircraft ditchings at sea have been accomplished.

    Now we have an opportunity to do something constructive: assist in promoting civil defense preparedness and hazard awareness for Katla and Eyjaf eruption meltwater flood and ash events.

    Free, recently published pdf technical paper you can access and download for educational purposes.

    Resident perception of volcanic hazards and evacuation procedures. D. K. Bird, G. Gisladottir, and D. Dominey-Howes. (2009). Nat. Hazards Earth Syst. Sci., 9, 251-266, doi:10.5194/nhess-9-251-2009.

    http://www.nat-hazards-earth-syst-sci.net/9/251/2009/nhess-9-251-2009.html

    See also, Supplement, hyper-linked at the bottom of the abstract web page, cited above (the evaluation survey sent out in 2009 met with dismal results – an alarming situation that MUST be remedied).

    It would be PRUDENT for IMO to expediently consider offering public access to this paper/survey in their News section. They should urge the authors for permission to reapply the survey cooperatively with the Civil Defense Dept. If authors, journal and agency parties are amendable, the survey should be distributed by mail as soon as possible to all area residential households. The survey results and discussion/analysis should be requested from the authors and applied,

    This would be the ideal public awareness tool to address risk reduction and improve Civil Defense response readiness for the upcoming eruption at Katla, which I can just about guarantee will take place in the next 6-18 months, as the precursor conditions are present and progressing as expected.

    Should paste it into Google and choose the translation link in the results page. That will give you the graphics title translations. The graph shows recent EQs plotted by date, magnitude, depth and Lat-Long coordinates.

    My other post, above, is relevant here, because the authors applied to the test survey to area residents to assess readiness of Icelanders to a Katla eruptions, fortuitously. Last couple of sentences in abstract:

    ‘ Our survey shows that despite living within the hazard zone, many residents do not perceive that their homes could be affected by a jökulhlaup, and many participants who perceive that their homes are safe, stated that they would not evacuate if an evacuation warning was issued.

    Alarmingly, most participants did not receive an evacuation message during the exercise (conducted in 2006). However, the majority of participants who took part in the exercise were positive about its implementation. This assessment of resident knowledge and perception of volcanic hazards and the evacuation plan is the first of its kind in this region. Our data can be used as a baseline by the Icelandic Civil Defence for more detailed studies in Iceland’s volcanic regions.’

    My guess is that the survey/evacuation drill will receive considerably improved participation response, now that Eyjaf has erupted with several major meltwater events.

Anyone who is living near Katla and the glacial tongues that are reaching the bottom or near the bottom of the cliffs, ect., should pay heed to the jokulhlaup hazard. I hope they will.

    On the THORO cam, the visual camera on top, open to “full screen” on your computer. Notice the vents in the forefront are steaming once again. The main plume is looking very healthy, like the eruption is increasing slightly. The visual camera appears to be working much better today, updated a few times a minute.

    The Norwegian national broadcaster (NRK) aired a National Geographic show on the Fimmvörðuháls/Eyafjöll eruption(s). The narration is in Norwegian, but parts are in English (and Icelandic…). The show can be viewed here: http://www1.nrk.no/nett-tv/klipp/634580 (Perhaps only within Norway)

    Seems like National Geographic is going to wait a bit before airing on its own channels:

It also starts loading somewhere lower in the page, so if you don’t scroll you can’t see it. What it DOES work is moving back the time-slider, which will give you the image from earlier on, which is also loading fully. Hope it helps for others too

    @ birdseyeUSA – I’ll ask!

    @ Suw – yes I saw that, thanks. Interesting that the plume from that other vent was jet black. Although I haven’t seen any further activity from that area. Could it have been just a phreatic event remobilising old accumulated tephra? That would explain the brief duration and the black colour. But then, it looked pretty hot on the thermal imager…

    I think Jón Frímann is right; I get the general impression, just a feeling, that the vigour is up but the volume is down; I think the vents are getting clogged. I’ll be interested to see how the system copes with that and what happens next.

    What’s stupid on the Vodafone’s refreshing feed, is that it loads the same image twice, then positions the top one to see the right side and bottom one to see the left side – it’s the same picture as on Picasa; if you copy either top or bottom, you get the whole five yards.

    The GSM data connection dongles are OK as far as you are in a G3 network; once they revert to GPRS, they are almost useless. Open WLAN networks are more useful, but be sure to have your security system up to date – well, that goes for any kind of Internet connection today.

I don’t have the expertise to know how to interpret them, however, but the FLIR seems to show that they are as hot as the main plume.

    @714 Passerby Have been watching all afternoon – when the renewed activity started, there was a burst in front (from Thoro’s point of view) and at one point soon thereafter, FLIR showed a divided plume. It’s smaller – on Hvol it seems that there’s the big plume (ash and all) and then a small plume pops up in front. Dunno – have been screen-shotting regularly but haven’t a clue how to get them up where someone else could see – have never used any online photo programs, such a computer dork, and on Mac at that, so Windows instructions don’t help – and I prefer not to use anything online where I have to pay – except maybe Amazon, which I don’t think will help!

    @ birdseyeUSA 679: I have an answer for you. “When we where up there it was not so loud, but two days prior to this trip I was at Gigjokull and it was like separate explosions, and very loud.”

    That kinda makes sense… the acoustic energy is going *up* from the crater, it probably sounds louder from a reasonable distance than from where they were 500-1000M away.

    We have to theories here for the presumed “double plume”
    1. A far-thrust lava bomb producing heat and plume
    2. The vent growing southwards.

    Have seen the lights numerous times. The pattern is the exact same every time. Also looked at Google and you can see road there. The distances are deceiving. Smoke/humidity accentuate the lights. The speed is similar each time too. Happens almost every night. Cars.

  789. #794 thor

    I had to ask for Pyroclastic flows, and now she has an eruption that can lead to that..

    Vulcanic eruptions..

    Pyroclastic flows are a common features of this type of eruption. The gas streaming phase of these eruptions are characterised discrete canon-like explosions, which are a particular features of vulcanian eruptions. These expulsions of gas can reach supersonic velocities resulting in shock waves .
    The tephra is dispersed over a wider areas than that from Strombolian eruptions. The pyroclastic rock and the base surge deposits form an ash volcanic cone, while the ash covers a large surrounding area. The eruption ends with a flow of viscous lava. Vulcanian eruptions may throw large metre-size blocks several hundred metres, occasionally up to several kilometres.

    what else does Eyjafjöll keep up her sleeves?

    In my humble and diletantish opinion, not Vulcanian. More Strombolian-Hawaiian. Frequency of bursts seems higher than the one in typical Vulcanian.

    If you go back and look at some of my posts from the last 2 threads and you will understand why it is so explosive.

    “Bomb is armed and fuel is lit” – this is how the National Geographic show on Eyjafjallajökull ends. And it sounds true to me…

  806. #811 Lurking
    May 9, 2010

    Well… it’s pretty obvious that there is a lot of pressure there now. Doing a fudge comparison with the camera’s viewing angle to the vent on Google Earth shows that that plume and debris is easily reaching 400 to 600 meters height.

    I’ve notices a few quakes at ≈8.3 km depth along a line to the base of the Reykjanes peninsula, likely following what is/will be connected to the Mid Atlantic Ridge in that area. Does this constitute a triple junction? Beats me. If so, that will be at least 3 of them in Iceland along the borders of it’s microplates. You can also see that there was some activity along a line ≈1.1 km depth towards the original ficcure eruption… and a couple of deeper ones a wee bit closer to Katla.

    For the experts out there… what are the possibilities that this magma will leak over into other nearby systems? Based on the historical record, it’s Hekla and Katla are both way early to be due for an eruption, Hekla only has a 10 year interval in her eruptions about 3.3% of the time, and Katla only has a ten year interval about 12.3% of the time. It’s been only about 10 years since they had activity. Torfajökull, off in left field north of Katla, has an eruption within 500 years 58% of the time, and it’s been 533 years since it’s last at 1477. The alignment of some of the quakes trends off towards the NE in that direction.

    None of this means squat as far as predictability goes… at least I don’t think it does.

    @GinaCT 831 – but how come that’s the only one seen at all all night? It was so bright and so fast – all the other explosions have been bright and have had white areas, but this was a single incredibly bright flash as though from a much hotter source – and the subsequent cloud is the only one that has shot straight up like a tower and been shaped like an ice cream cone on top – just curious ….

    It’s just after midnight here, so I have to get some sleep. For those just coming on tonight, the EQ activity, lava fountains, steam vents, and lava bombs were simply awesome and deserve some review. It was great watching it with all of you! Good night ya’ll!

    Could someone just clear up a niggle for me – the steam plume on the Hvolsvelli cam on the left hand slope – that’s the same plume as on glacier, right? I am assuming so from position of cams, but haven’t noticed it on Hvols cam before.

    The vodafone camera view right now (11:20 PM CST) is really clear. The ash looks completely different then that from just a week ago. Nasty brown muck. Since the composition is increasing in silica does that mean that the basaltic magma has cutoff from feeding the chamber and we’re just venting the old melt (a little house cleaning) before going back into dormancy?

  860. #865 Helen Leggatt

    May 10, 2010

    Anyone seen the latest analysis of the ash….that will tell us more about what’s going to happen next. I wonder if the silica content has down or up? According to yesterday’s report it has been steadily increasing since the fist eruption….that is in spite of getting recharges of what should be very mafic magma. Also the ash plume has been getting lighter gray….when this all started it was black.

    Posted by: Mr. Moho | May 10, 2010 1:14 AM

    More ash does seem to be falling out sooner. The eruption is still pretty energetic and getting it up there a ways, so I’m guessing the ash is getting heavier. Could be coming out as coarser particles, which would fall sooner. But also, the plume appears to be lighter in color, which hints at a change in composition.

  874. #879 Helen Leggatt
    May 10, 2010

    The ash plume looks just as murky and dirty as it did earlier, however a new plume of steam (to the left of crater on Thoro cam)appears to be mixing with it to make it lighter in places. I assume new lava outflow.

  875. #880 Helen Leggatt
    May 10, 2010

    There’s very little steam venting from further down near the wall of ice, particularly compared with a couple of days ago. Just wisps at the moment yet the heat cam shows a lot of heat down there. Why might that be?

  876. #881 Randall Nix

    For the German speaking members on this blog: There is a new article at the news magazin “Der Spiegel” regarding Eyjafjallajökull and the closing of the airspace in April:

    http://www.spiegel.de/wissenschaft/technik/0,1518,693801,00.html

    It reports that the pilots that flew the first flights under ‘sight only’ rules in Germany were in fact very unhappy to fly under those conditions. They state that it may not have been safe to fly during those days, even without the danger from the ash.

  878. #883 Jón Frímann
    May 10, 2010

    I think that the current vent might be getting bigger. But so far it does not appear that a new vent has opened up. But the risk continues to be there at current time.

    I suppose all the night-watchers are sound asleep, I´ll throw out a question anyhow.

    Picture´s/screenshots/videos from the past night? I posted my screenshots from Hvolsvelli cam on flickr http://www.flickr.com/photos/50029293@N05/?saved=1 Note: the pictures are not in the right time order in the album, start looking at the last, that´s the right looking order if you want them in chronological order. Time from 22:00 to around 1:00 in Iceland.

    I didn´t have a working Thoro or vodafone cam yesterday (slow computer), anybody got some nice screenshots?

    Amazing how calm she looks in daylight, tonight’s fire cascades very a strong demonstration of the forces of Nature.

  885. #890 Mr. Moho
    May 10, 2010

    Is it only my impression or from the FLIR camera there is really more hot material deposition at the feet of the ash plume (which also seems hotter) and down the glacier than usual?

  886. #891 Lavendel, Switzerland
    May 10, 2010

    #885: I get the same impression, Moho. I also have the impression it extends farther down as befor.

    Maybe because more ice has melted and so the lava is more “visible” ?

  887. #892 Ruby
    May 10, 2010

    @885&886 Yes there is more and it does extend further down I was up very late last night until 3am uk time and it looked like she just spewed it out over the edge but I shall have to watch the time lapse video when available to get a better look. It was just amazing last night the best I have seen yet I ended up only getting 4 hours sleep but well worth it:)

  889. #894 Suw
    May 10, 2010

    Warning! This comment contains supposition!

    @renato #711 Yes, that looks like the same sort of event that Fireman captured and that showed up on the FLIR camera. An yes, I’d agree its placement is consistent with the FLIR and the other screenshot.

    I’m not sure if it’s just that the plume is suddenly billowing sideways, because it looks a lot more like it has an upwards motion rather than sideways. But stills can be deceiving.

    @passerby #714 I’m even less sure that it’s coarse ash particles dropping out – that is happening, but on the downwind side of the plume, and it looks quite different to my eye.

    @Kultsi #718 I’m not sure that the second plume is the result of a big lava bomb displacing tephra because firstly I think it’d have to be a *really big* lava bomb to create a plume that high, and secondly, the plume would surely have a different shape? If you look at this diagram of crater impact formation, the ejecta would look very different to the billowing cloud we saw.

    http://astronomy.nmsu.edu/aruiter/ASTRONOMY110/CratersComplex.jpg

    To me, the billowiness of it indicates convection, and that it was hot was born out by the FLIR. Would lava bomb impact ejecta be that hot?

    @thor #727 Pyroclastic flows happen when an eruption column collapses under its own weight. There have been warnings that pyroclastic flows are possible from this eruption, but I’ve not seen any official reports of any so far.

    @Christian, you keep mentioning ‘lava bursts’. Can you explain what you mean precisely. I’d google, but all I get are references to World of Warcraft…

    Finally, a plea to everyone who’s awake when I’m asleep. If you see something cool, please try to get a screenshot! If you’re on a Mac, then Skitch.com is great – it’s not just a screen capture tool, it’s also a website to upload to. I’m sure there’s an equivalent somewhere for PC.

    Flickr is a good site for hosting images – its basic account is free. There are loads of other services as well, so plenty of choice.

    I never get to see all the nighttime shenanigans as I’m asleep, so screenshots would be great make us Europeans feel less like we’re missing all the fun!

    And on that note, thanks to @Raving for the screenshots. Wow, she’s pretty impressive at night!

    Hello there! Just a brief comment before I go to work:
    What is that reddish cloud or fog that appears on Múlakot cam? (http://www.simnet.is/jonfr500/earthquake/vefmyndeyjafjalmulaen.html) It seems coming down the western slope of the volcano. If it weren’t so “hazy” it could pretty much look like a piroclastic flow. But could also be a blurr on the image, but it persists when refreshing. Just take a look.

  900. #905 Mr. Moho
    May 10, 2010

    @895: I noticed that too, I wonder if it’s cultural noise or sequences of many small earthquakes.

    Two questions for for Jon:
    - Wouldn’t applying a low pass filter of 10 Hz instead of 5 Hz better capture local small earthquakes by the way?

    - Are you already using the Earthworm seismic software suite to process data from your seismometer(s)? If not, consider using it as it would easily allow many interesting things (better/more advanced helicorder charts and spectrograms for example).

    Big explosion now, about 10:45 local time

  905. Thanks everybody for saving some of the spectacular moments that the webcams offer at night – some of them are really impressive. It seems that this night the incandescent bursts have been taller than before, it looks like 200-300 m in height. I don’t know whether Jón’s information (#884) about the ash plume being 10 km tall is realistic – the whole morning I’ve seen it being about as tall as the mountain itself, and that’s less than 1700 m. I’d give it at best 5000 m (altitude above the sea level) throughout this morning. Certainly, the plume has become again much darker in color than it was in the past few days; that might mean there’s a compositional change toward more mafic material – hopefully some new analysis will be published soon.

    Someone a few days ago wondered whether the latest chemical analysis (with something like 61 per cent of Silica, SiO2) was dacite. It’s not, it’s still andesite (dacite has >63% SiO2). In any case the increase in silica content throughout this eruption is truly quite unique, it will be fascinating to see what will come out of in-depth analysis of all that material, both regarding the eruptive products and the geophysical (seismic, deformation) aspects. Though I fear this will happen only in a few years, considering the Icelandic scientists are being kept very busy for the moment, the analyses and interpretations will take their time as will the writing of scientific papers plus the editorial process they’ll have to go through for publication …

    May be a dumb question:
    what is the white “stuff” at the foot of the gletscher? It has grown bigger as yesterday. At first I thought it was water, but it is to slow for that.
    A mudslide? But why is it so white then?

  907. #912 Mr. Moho

  908. #913 Henrik, Swe
    May 10, 2010

    @Jón (#884) Where did you get that figure from? Judging from the webcams a figure of ~10,000 m does not seem reasonable, at least not in the vicinity of the volcano.

    @everyone. When you judge the height of the eruption plume, only the Hvolsvöllur cam is useful as the others are too close and give a faulty perspective. The highest peak of Eyjafjallajökull is 1666m above sea level. Using the apparent height from Markarfljot (level flat area at lower right in camera view) to the top of the mountain gives a useful figure of 1600m (1 mile / 5,250ft). If you use a ruler to measure height, you will see that usually, the eruption plume is no higher than about 2,000m (6,560ft) above the summit or ~3,600m (11,800 ft)above sea level.

    Using the same scale, the distance to the top of the screen is about 3,300m (11,000ft) above the summit or just under 5,000m (16,400ft) above sea level.

  924. #929 Kultsi, Askola, FI
    May 10, 2010

    @#906 Lavendel, I think it is water channels/mud left behind by the meltwater coming down the west/right side of the glacier; as the meltwater input has abated, the moraine left behind has dried some and now lets some of the water seep into it, but apparently the mud clogs up the moraine, so the channels extend farther and farther. The amount of water from the right side is larger now than in some previous days.

    Last night’s show was awesome, my husband and daughter were even interested.

  935. well. that’s 35 earthquakes in the past hour. I don’t know whether a new vent will open or rather those vents that opened within the caldera on 13 April and then became inactive will reactivate. Thomas (#928), I don’t see any reason to expect Katla to erupt now, all the seismic activity is at Eyjafjallajökull in the moment (except for one small quake further toward Katla) – and the Icelanders really wouldn’t need that …
    Pyrotech (#931), looking forward to your video. Here on Etna in my hometown Trecastagni we had to content ourselves with the fireworks for the local patron saint, Sant’Alfio (but the fireworks were spectacular).

    I think many more small earthquakes occurred between 09:00 and 11:00 UTC will be added to the official list at a later time, then.

    #936 I meant to say EQ activity over the whole of Iceland and not just the Mýrdalsjökull region..

    An exciting lunchtime on all the iceland cams!

    Greg, I find the Table tab on the Met Office earthquake page helps you see which EQ has just happened.

    Also, the melt water appears to be steadily increasing again- lots of little stream showing at the base of the morrain(?forgive me if that’s the wrong term). It could just be the sun on the water, but it had tailed off quite a lot in the last day.

    Loving the timelapses – thanks all!

    whats up with the cams?? all seem like they are down at the moment..
    One quake near katla, and 35 at eyjafjöll, now shes up to no good..
    Had an small quake here in Norway last night, not sure if that is linked to whats happening on iceland, but I would not be surpriced if it was..
    we all live on an living and ever changeing planet , and some how all is pretty much linked to gether, remove a piece of the puzzle and h!#” breaks loose

    @Shelly

    I don’t follow the EQ activity closely, sorry. The latest barrage of quakes (almost 40, starting at 11:00 GMT) was reported in the news but scientists don’t believe it signals something catastrophic is going to happen. Perhaps more magma pushing up.

    There’s less ash today and the lava flow is increasing somewhat.

  945. #950 Paul

    Shallow quakes circa 1km depth in the valley to the north.

    Deeper quakes circa 20km depth under the volcano itself.

  946. #951 Carl
    May 10, 2010

    42 EQs in under an hour…
    I rather hope that is a new went opening up, because I think the alternative would be even worse.
    Because if there is a sudden large presure build-up without a new place to go it might go rather Krakatau on us.
    The reason for me thinking like that is that this Volcano seems to have a rather complex tubing system and if that is shaken around enough the magma and gas release rate will sky-rocket like an erupting geysir. Thing is that I kind of think that is why we have this large swarm, shakes happening all over the tube system shaking loose a lot of new gas that will make a rather huge explosion when going through that rather narrow throat of Eyja.

    Thanks Anna, maybe someone else can answer.. :) I’m loving the way the top of the plume is playing with the cloud cover..

    @946 I’m amazed that the ashfall you can see on the Mulakot camera can be less then yesterday. It looks pretty dire. Maybe the wind has changed from the sensitive areas.

  949. #954 Mattias Larsson
    May 10, 2010

    What is happening. This activity scares me a bit. It reminds me of the activity before the main vent eruption started. Only this time the earthquakes are occuring on depth all the way from 1 km to more than 20 km. A new puls of magma coming up the main vent from 20 km depth?

  950. #955 thor
    May 10, 2010

    I am fearing the same Carl.. if this new preassure build up dont get relesed, she might blow the main crater.
    then we can start talking about an Eruption much much larger that it is now, this Lady has more up her sleeves than we know about.

    hopefully as long as shes not blowing outwards like St Helens,it wont get to bad.

    Jón @ 881 – excellent find! Thanks for sharing.

    If anyone wants to see the ash column from really far away, RUV has panned the Hekla camera to the right a bit.

  953. #958 Thomas Wipf
    May 10, 2010

    @Boris That sounds to be a good explanation: Maybe the old vent starts to erupt again! Let´sm hope Katla will stay quiet!

    Wow I’ve just got back in, what is with all these EQs that’s an awful lot in such a short space of time, she put on a real show last night but all these EQs what does it mean

    More shaking on the way after a short break http://www.simnet.is/jonfr500/earthquake/tremoren.htm

  956. #961 Henrik, Swe
    May 10, 2010

    A perhaps more realistic scenario than the Katla one is if there’s a basaltic intrusion in the Godabunga “cryptodome” and that erupts. IIRC the Godabunga intrusion was attributed to the Eyjafjölla volcanic system, not Katla. However, why should there be one when there’s an open conduit all the way?
    (If you look at the IMO map for the Myrdalsjökull area, Godabunga station is the black triangle about 8km SW “M” in Myrdalsjökull.)

    Good morning all! Bom dia @Renato! Does anyone know how much the volcano has inflated in the last few days? The show last night, coupled with the EQ activity means she is really gearing up for….something. But what?

  959. #964 Anita in Austria
    May 10, 2010

    Did anyone else see rocks being hurtled out (at least what appears to be several km to the left) on the Hvolsvellör cam?
    If so, then things must be getting very, very dangerous for the people living in the surroundings, let alone for scientists venturing onto the glacier or anywhere near.

  960. #965 Mr. Moho

    @955: the last one looks more like a large harmonic tremor burst. By the way, as I wrote before, many smaller earthquakes appear to have occurred between 09:00 and 11:00. They haven’t appeared yet in the earthquake list on the Iceland met office website (vedur.is).

  961. #966 Alison, UK

    @959 I saw one a few minutes ago. It went across the sky to the left, looking like a meteor on the thermal cam.

    @961 Alison, yes I seen that too it went so fast if you had of blinked you’d have missed it

  963. #968 Passerby

    Vertical tremor plots all show very low activity. No new vent. Depth of EQs indicates more magma moving upward from deeper locations, pressurizing the conduit and possibly remelting and activating existing vents.

    Those of us who study volcanic emissions impact would very much like to see a new ash particle size analysis conducted with repeat comparison of samples collected over distance, please.

    Also would very much like to see the plume gas analysis conducted last week, IES. The clearly visible blue haze and reports of odd smells at altitude by passengers in planes suggest enriched sulfur and halogen emissions, but we’re also thinking perhaps certain metallic elements may be present at higher concentrations than expected.

    Perhaps UK university collaborators could be tapped for rapid deployment of air quality samplers (gas and particulates).

    @passerby: Just for curiosity, about which elements do you think?

    Earthquakes from the last smaller swarm are starting to appear in the official list. I hope those occurred between 09 and 11 UTC will soon be added too.

    @962Ruby and 961 Alison,
    The rock must have been huge because I saw it on the Hvolsvellör cam, which is 30 km away.

    Ok the Video i caught last night has been cut down to under 3 mins. It does linger on some frames as was captured whilst in work on a dongle thingy. But the sequences clearly show the lava being thrown hundreds of feet in the air. It was taken about 1 AM UK time today.
    You may have to add windows media player first time which when you click yes on top of your screen takes 2 seconds as saved it as wav or avi.
    I will add more video footage as days go on.
