iceland Bárðarbunga and Askja - Volcanic Activity

Just as you posted the SO2 map Rustynailer, weather forecasts are showing direct winds from Iceland into Norway by Tuesday 9th Sept then NW UK by Thursday 11th Sept. If SO2 emissions continue at present output do you foresee any Health issues for Countries down wind?

I don't know enough about the subject to give a definite opinion, I suspect that the SO₂ is going up higher levels and being diluted all the time , so my thoughts are no not at the moment, but if this type of SO₂ output continued for months then yes I think it would start having effects on some people. Only an opinion from an amateur and that is all.

 

The now 10-11sqkm lava field is still out gassing, in fact it gives off more SO₂ than the erupting fissure according to Carl on VC Blog.

 

 

Still going on Mila Bada 1   

 

200 meters ?  I think so 

 

Scientists going home rather than a new vent I think

MACC has a five day forecast for different atmospheric levels.

That is good I have not seen that one before, here is the noaa output now  http://satepsanone.nesdis.noaa.gov/pub/OMI/OMISO2/images/OMI_NH_SO2_DDC2.GIF

 

The Macc link has not factored in the Volcanic SO_{2 from Iceland yet. eg:-  @ 3000m} http://macc-raq.gmes-atmosphere.eu/som_regrid_ens3D.php?datemodel=20140904&mod=ENS&niv=3000&param=so2 It has the Reykjavik urban outgassing on the other hand  I suppose it will given time.

 

Interesting;  Jon Frimann says "Toxic gas has been measured up to 6 km above the eruption craters." jon's comment at@ 22;49 Iceland time or there abouts.

as an ex chemist, I have my doubts as to whither the S02 will have much effect on the winter unless we got a big bang. SO2 is a heavy gas and will stay in the lower atmosphere unless there is a big explosion. I think it needs to be in the upper troposphere or Stratosphere to affect our weather with Blocking.

I may be wrong, if I am can one of the experts put me right

It does if you use the global forecast available from the home page. The question was about Europe so posted that link.

another 4m+ earthquake also the time it lasted is longer so something going on

LAKI was a fissure eruption and the gases didn't go high in the atmosphere but it radically changed weather patterns and caused a cooling which lasted a few years but that was a bigger fissure eruption than this but the so2 at low levels can still affect the weather in a big way it destroyed crops and that back then as well with acid rain and an acidic fog which was over Europe like I said though that was a far bigger eruption than this one LAKI was 27km long and has one of the biggest lava flows in the world.

I agree with what you say there, but I was only referring to Blocking patterns. The acid rain and all the other problems --- they win depend solely on the size of the eruption.

Also, the Wikipedia entry (hopefully correct) says it started with phreatomagmatic explosions. That would have given the Initial burst into the high atmosphere.

Two overnight earthquakes have just been upgraded to a 4.3 and 5.3 in the Richter scale.

Bada 2 the fissure , there might be further development in the foreground.

 

I think it may be steam rising out of the ground, this could be significant, saturated alluvial deposits are dangerous in situations like this, explosions can happen. 

I emphasis can and might here, it may be nothing.

 

 Is it bigger now and 2 of them ...  Fumaroles?

I saw what looked like steam a few days ago, but then again it might have been just dust blowing past the camera's.

 

I've been reading up about past eruptions in the 1700's and although we are nowhere near those at the moment the facts of the events just goes to show how insignificant life is on this planet and the ability of the earth to snuff us out in an instant!

That is what I like about volcanoes they are so risky, its as interesting as storms or snow to me  I am still thinking fumaroles at the moment, I do not think they are like the dust devils we have been seeing here.

The fissure sure is doing some dark outgassing in the background today, bet the SO₂ is sky high.     

 

A Doppler radar truck has arrived to watch the explosion, sorry probably not, just arrived to watch and get data

Link regarding the 2 new Fissure that opened up South (closer to the glacier) of the  current eruption.

 

Don't know if it has already been posted. Apologies if it has.

Good catch that. I wouldn't have seen them

This is a good view. Is that the edge of the glacier bottom right?

 

Wording on the page translates as follows:

 

00:12 it is to the new fissure opened in the morning, close Dyngjujökli, and former crater. Lara Ómarsdóttir reporter took a video of the new volcanic rift just north of the perimeter Dyngjujökuls this morning is the first video clip of the new crack.

2.  The new fissure from overnight.

3.  Old fissure.

4.  Fumarole possibly.

5.  Dyngjujokull glacier.

Thank you that certainly shows well.

 

Still developing in the middleground   

 

Oh I have just had a brainwave, I bet it is lava flowing on the surface from the oldest fissure, it is outgassing and steaming in contact with water on the alluvial floodplain....
