Eruption Pollution Drifts to Germany By Zoë Robert September 24, 2014 09:01

The pollution in East Iceland earlier this month. Photo: Zoë Robert.

The sulfur dioxide (SO2) pollution from the Holuhraun eruption has spread to Germany, Spiegel Online reports. With wind blowing from the northwest, the pollution is being felt further to the east than previously. 

Earlier this month, people in Norway and Sweden complained about the pollution.

Both the German and Austrian Met Offices have measured the pollution in central Europe. However, neither in Germany nor elsewhere outside Iceland is the concentration of SO2 high enough to pose a threat to humans and animals.

have a look at link

a few more updated stories there

[NorthNorfolkWeather]

well, it's keeping us guessing ( and waiting)

 

I thought I was beginning to detect some form of pattern in the quakes, but that last group around 18:00 put paid to another theory

 

The quakes at the caldera are definitely edging closer to the surface on the E/NE Flank.  I suppose if it does blow we have to hope the jet stream is heading away from us if we want to avoid too much disruption.  Looking at the charts, the only time the Jet stream would be a problem is the next 3-5 days (assuming GFS is right after day 5)

Video: Scientists move burning lava into a pot

Kolbeinn Tumi Daðason skrifar:

Scientists at the Institute of Earth Sciences at the University of Iceland are still very much at work at the lava field Holuhraun north of Vatnajökull. They have released a video which shows them shoving burning hot lava into a pot and cooling it with water.

watch the video  :shok:

 

 

The video reminds me of the film Volcano, where they diverted lava out to sea.  You couldn't see that happening in real life looking at that  --  inexorable forward movement.

another v shallow one

 

hi norfolk

the lava looks very hot and not sure i would like to attempt that

 

diverting it

have a look at this

that one looks like they cannot do it

 

the quakes i am looking for are quick one after the other swarms now or obviously a biggie

 

but it will keep us guessing until it decides it cannot take anymore pounding

 

probably at 3am when we are not looking

another spike there

and theres another biggie

Nothing of great substance since your report, few minor quakes otherwise quiet.

 

Another day of waiting

Yep, still non the wiser!

No sign of the current eruption lessening and large volumes of SO2 continue to be produced.

 

 

But the eruption is also notable for its release of gasses, particularly the amount of sulphurdioxide (SO2). Þorsteinn, who is a geophysicist that specializes in atmosphere quality, says that exact numberrs are unavailable but he believes that the amount of gasses discharged is around 10-20.000 tons a day, though certain measurements show a higher density.

"The gas emissions from Holuhraun are around 10-60 thousand tons of sulphur a day. By comparison the EU nations release 14 thousand tons of sulphur a day, and then we're counting every possible source; industry, energy production, mass transit, heating, etc," says Þorsteinn and adds that in that context the Holuhraun eruption is far from being a minor eruption. Quite the contrary.

According to a poster in the Stratosphere temperature thread, all this SO2 can help increase the ozone levels which then encourage high latitude blocking. So winter lovers take note :-)

 

But before you get too excited, have in mind that most of the SO2 won't get that high up as the eruption is effusive and also unsettled weather from now on (wind, rain , snow) make it fall back on the ground.

Very quite before that M5.0  seems that a big quake now shakes everything down and it takes a day (or more) of strain before we get the next biggie.

 

 

North East side again I see, there has been a huge release of energy on that side of the caldera since this started.

Bardarbunga volcano update: Eruption continues at record-breaking lava output rate

Thursday Sep 25, 2014 21:25 PM | BY: T

Webcam view of the eruption this evening (Mila webcam)

Location of today's earthquakes near Bardarbunga volcano (IMO)

No significant changes have occurred at the ongoing eruption in Holuhraun and the seismic crisis. The eruption itself continues with steady, very large lava output and is on its way to become the largest event in the past 150 years on Iceland.

So far, it has erupted approx. 0.5 cubic kilometers of lava, covered 40 square kilometers at an average depth of 12 meters.

During the past 150 years, only the Hekla volcano eruption in 1947 (which however lasted 13 months) has produced more lava. If the current activity goes on for another 2 weeks at the same rate, it will beat this record.

Gas releases are record-breaking figures: approx 10-20,000 tons of gasses (mainly SO2) are released each day.ejected amount the current eruption is record holder. Volcanic gases are discharged daily between 10,000 and 20,000 tons.

A road (Gæsavatnaleið) used to access the eruption has been covered by lava flows, making it more difficult to geologist to get to the eruption.

Seismic activity

A magnitude 5.2 earthquake occurred this morning under the Bárdarbunga caldera, which keeps sinking at 50 cm per day. Its total subsidence is almost 30 meters now.

Earthquake activity has slowly increased again under the active dyke, which could indicate increasing pressure and involves an increased risk that new fissures open up, possibly under the glacier.
