Eyjafjallajökull Update for 5/7/2010

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 GÃgjökull 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...

@Zander - MÃla finally changed the page names to line up with the camera locations. You can get to them from this page: eldgos.mila.is

@Dasnowskier i'd say the plume is about 421,000 feet very soom it'll be in earth orbit and they will be collecting the dust in the ISS.

Reports are its at 31,500ft

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.

On the other hand, the new colour cam might look pretty damn good at full screen for those with a widescreen.

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 Ãórólfsfell (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/el…

haha 54 soo true i was just starring at this picture like crazy.

Thanks for that zoom, dude.

I wish they would switch off autofocus on the new Ãórólfsfell camera, every tiny movement from a gust of wind sets the autofocus off and makes the image blurry for a split second.

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?

@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.

If you look closely, I think you can see the Lady: just to the left of the split stone, twice as tall as it, to a background of the white parts of the glacier.

#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.

#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 HÃ¥kon 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, Ãlafur Freyr GÃslason, Guðrún Larsen, Benedikt G. Ãfeigsson, 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 KeflavÃk 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 VÃk 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 GÃgjökull 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 Ãslands.

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 GÃgjökull 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.

birdseye do you have the picasa link for todays photos, my link is missing, I´m sitting at another computer, and that one I didn´t memorise.

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

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.

@motsfo #135 I'm not sure it is. The view from Ãórólfsfelli 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/EyjafjallajokullVolca…

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 Ãórólfsfell 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....

Johann Wolfgang Von Goethe, Nature, a Fragment

@132: Maybe Eyjafjöll is not the main event but only acts as a "safety valve", letting pressure off when something else gets blocked? Most tremor graphs along the rifting zones (roughly Kistufell-Eyjafjöll-Reykjanes) show almost identical features.

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 glacierâ¦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).

did anyone see if the white car that just exited stage left had crossed the river (i.e. come from the main road)?

@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.

Can any anyone advise how to take screenshot from Mila cams, Adobe website says to right click, but that's not giving me the option.

Based on previous web cam views that were similar I would guess 25 to 30,000 feet. The mountain is about 5,500 feet for reference.

@ 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.

OK! Who sneezed on the Ãórólfsfell cam? :)

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.

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?

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"....

By parclair, NoCal USA (not verified) on 07 May 2010 #permalink

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.

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.

>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.

No. Seismic activity is back to baseline.

By birdseyeUSA (not verified) on 07 May 2010 #permalink

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.

@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.

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)."

Hi, been lurking and learning for some time now. I would like to say how much I am enjoying this blog; loads of information.

Has anyone else spotted that small stream of steam just above the rock fissure in the Vodacam view? I first saw it about ten minutes ago.

@231...

In fact, there is one... Santorini ;)

If it too started to erupt in a gentle, Strombolian fashion (as it did a lot of times in the beginning of 20th century), it could attract even more tourists into this already touristic island....... and given the panorama you have from Thera island, tthe view would be awesome...

#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

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.

@ 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.

A clear view in every camera! Even the Ruv.is cameras have a good image. The ash from Eyjafjöll has turned the Mýrdalsjökull almost black.

*grmbl* Massive blackout up here last night. Took out W-, N and E-Iceland. Good thing it took only about two hours to fully restart the grid.

You can spot the occasional bit of falling ash on the Katla cam. Mýrdalur, which is nearby, is hard hit by ash fall. The village VÃk saw 300 micrograms per cubic metre this morning. The danger limit is currently set a 50 µg/cm³.

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.

http://www.yr.no/satellitt/europa_animasjon.html

It also seems to me that this is getting much worse than when it first started (the 2nd time) Does anybody else see it this way?

Does anyone know where I can get a pre-eruption image of the volcano from about the same location as the Ãórólfsfell webcam?

I teach a High school Earth Science class and I want to show my students the change in the glacier.

After nightfall, or in low visibility, it seems the only way to monitor activity is through satellite imagery or through seismographs, especially so with the sub harmonics.

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).
3. (pH 5.55) Fluoride 112 ppm (Fluoride and pH measured in meltwaer).

@Doc AFAIK, the Icelandic people are well aware of the danger - they've lost enough people & livestock to fluoride poisoning before.

By Kultsi, Askola, FI (not verified) on 08 May 2010 #permalink

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.

Look at the way MET was treated for trying to save lives. I guess people care more about convenience than safety.

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.

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 GÃgjökull. 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.

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.

@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.

Plume looks big again today. Anyone have summary of todays activity?

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.

"Update on activity
Eruption in Eyjafjallajökull, Iceland
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. For latest information, see the status report issued collectively by the Icelandic Meteorological Office and the Institute of Earth Sciences at 14:00 today."

Watching the antics on the Ãórólfsfelli 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?

Is anyone plan to produce or already have 24hr timelapse video from thermal camera? Thanks!

Well, there they were, and one of them was Leifur - and the Vodafone cam was down. OTOH, Mila's camera worked well enough.

I did learn something: Vodafone faithfully archives the current.jpg, regardless of what's on it; right now it's the 20:06:32 image. So, Leifur did not succeed in getting on Vodafone's pics & the daily video...

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

My uncle and his wive where on the MÃla cam earlier, along with her son. I don't know the fourth person. At one point, they where all three standing and waving to the camera.

Currently there is only one vent open, it seems. But that might change without any warning now.

The Eyjafjallajökull eruption and the interuption to 'normal' day to day business just emphasises humanities limits and our ultimate subserviance to the natural world. Money is not wealth and all real wealth is limited to natural resource.

@ Jon Frimann, Hi why do you think that another vent may appear ? Is there some kind of pressure build ?

Jón - would this be your crew?

http://www.corestore.org/jonscrew.jpg

As for vents, how do you explain the image I posted earlier? One crater maybe, but more than one active vent in it? You can clearly see the shadow of the plume from the second vent on the main plume.

If that other person on the web cams is Leifur he is taking photo's.. Can't wait to see them. lol

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?

By Henrik, Swe (not verified) on 08 May 2010 #permalink

@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. ;)

@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.

#397: A sideways blast 'below the horizon' might cover it, too.

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.

I've been wanting to learn about data visualisation and such things for ages now, and this is a grand opportunity to do something that might even turn out to be interesting!

It's a pity the webcams don't have sound i'd love to hear the eruption. I've read that the eruption could be heard 200 km away at times.

@dan Flickrs good like that. I find it really useful sometimes to annotate pictures, and this is a case in point.

You may wish to consider adding ab archive page to the Eyjaf Wiki for time-lapse movies of the eruption (webcam and FLIR). That would be quite helpful for anyone wishing to view and compare activity periods.

Similar archiv of EUMENSAT satellite plume models would also be helpful.

@ 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.

@401 No croaky voices here on Skye. Actually it's been quite disappointing that there do not seem to have been any decently coloured sunsets here since the eruption started.
I was rather looking forward to highly coloured sunsets from the ash.
Also we have had great weather the last couple of days, quite warm and blazing sunshine, quite contrary to Bev's experience.

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.

The delay on the Axis cam is pretty bad, but the FLIR cam seemed to show the plume get much hotter for a few minutes at around 22:10. Still waiting for the other camera to catch up and show what that looks like.

@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. The wiki is editable by anyone who wants to make an account, although so far the only 'help' I've had has been from spammers!

@Suw 421: it was on the Ãórólfsfelli 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!

Thanks for the William McGonagall poem Gordon. I like it, it's spirited and imaginative.

And now I know where this spoonerism comes from, "Iceland's greasy mountains".

Socuel has archived validated EQ data back several months; contact him here:

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.

>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.

@Gordys: There is many different open sorce softwares that can be used I used for this one " MakeAVI-0.11 "

it can be downloaded from http://makeavi.sourceforge.net/

I can help..that is my day job.

So - I'm back from my expedition to Ãórólfsfell. As oberved by someone here, the Vodafone camera was down so I shan't be able to admire myself - but then I wasn't primarily for that purpose anyway! I hope I didn't get in the way of any scientific observations by you good people.

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 GÃgjökull).

Vodafone cam is back up and running, but it's dark :(

Mila cams are down - perhaps the took them off line to teach us a lesson about dissing their autofocus!

Fingers crossed that morning will bring us something to look at. I'm stuck in the house for a while because my daughter has chicken pox.

Looks like the cameras are down for me also...just as well, I have a sink full of morel mushrooms to take care of.

Leifur, I think I got several screen shots of you (were you wearing a blue/dark grey outfit and later donned a blue/grey anorak?

@Gordys not a stupid response at all. I'm grateful for the help and glad it's not just me. :) Forget the 'shrooms and grab that fuzzy blanket!

@Frito Lay

Yes, that sounds about right. It was a bit windy up there so we had to add layers (the pair referred to as "Jon's crew" above were travelling with me).

My posing was primarily for the benefit of my 5-year old grandson - by coincidence he had been on the TV news (they had been doing some filming at his kindergarten I think) so I had to try to match that - he was watching his grandpa on his father's computer.

If it's not too much trouble, drop me a line at leifurh@hotmail.com and attach a picture.

Leifer I've sent you an email with a pic. Let me know via return email if it's you.

Cheers.

Ok. What has happened to the cams? I went to the site I put in my favorites and all I get is a map of were the cam is. Can someone post the correct address for me?

Thanks.

As you can tell, I have been away for several hours.

@Diane #483 The cams have been down for about an hour. Reynir? said there was a massive power outtage in N, E and W Iceland last night. I hope the same thing hasn't happened again tonight. (-:

Outstanding paper worth slogging through as a learning tool with great cartoon graphics, as it describes the mechanics behind the 1998 Gjálp and 2004 Grimsvotn eruptions.

It explains the effusive eruptive (Fimm) and explosivity phases (crater) we are presently observing at Eyjaf.

Subglacial and intraglacial volcanic formations in Iceland (2006).

Thanks Frito Lay. I was wondering! It sounds like I missed a bit this afternoon my time, which is night in Iceland. I hope they can get the cams back up before daylight and that we will be able to see what is going on.

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.

I think they said on the news that they expect Reykjavik Centre to handle 600 trans-Atlantic flights this Sunday. I miss shift work :-(

Quick, someone make an offering to the huldufólk, FSM, IPU or something. The cams! We must have the cams! I'm sorry I complained about the autofocus and the lockups! :p

Next person hiking up to the cams needs to put Erik's URL on a sign. Give our humble host and his Scienceblogs overlords some extra traffic. Oh, and if you're a Pharynguloid, WTF, bring a squid too.

I've just heard on the TV that flights from South America to Portugal, Spain, Italy and France would be cancelled. (I'm from Rio de Janeiro) I had no travel plans for now, but they say it may take some more time before closures will stop.
By the way, have you heard of earthquakes NE of Tambora, Indonesia? It's stays on John Seach's page, who happens to be in Iceland and has an Youtube link of his Eyjaf's adventure.

Should we expect any activity on the Indonesian volcano?

Thank you for the link Passerby, I will give that a through read in the morning. The cams are down, the shrooms are taken care of, it is time for bed....and Frito got lost on the way over(heavy sigh). Good night.

It appears that part of the Vodafone network did go offline tonight. I do not know why. But that made my Hekla sensor to go "offline" from my client end at home. It has just started again now.

It also might explain why some cameras have been offline part of the night.

@361/Henrik - thanks for the explanation. I read Boris' Etna page from time to time - but shall make it more regular and get in to the history of the Italian lady (the volcano - not Boris!).

I've seen Stromboli erupt a few times on trips to Italy, and Pompeii is one of my favorite places in the world...

Daylight on Múlakot cam and Mila's seem to be awekaning.
Clouds covering our lady.

Ash plume is not visible over the clouds. As Leifur stated: "Regrettably the volcano wasn't very active - or perhaps we just didn't wait until it was properly dark."

Here's a good satellite image from 10/5/7 showing the ashfall on Eyjafjallajökull and Mýrdalsjökull:
