iceland Bárðarbunga and Askja - Volcanic Activity

Thanks John and also Yarmy....

The graph looks fairly flat altough still slowly dropping.

It is nice to see it back again though.

It is not working for me. I still see the old image.

hi karyo

 

try going on it and pressing f5 a few times

Thank you John, it works for me now. :-)

[john pike]

no probs karyo

 

i think my f5 button is wearing out now :-)

note how shallow these are

[Midlands Ice Age]

Guys,

Go quickly to cam1 - 2 flying saucers howevring over the site!!!

OR could be superb examples of Lenticular clouds!

Seriously though I think the cam1 must have swung round to the NorthEast as still no fires are shown

MIA

Update

The saucers are now combining together - what next a new generation of saucers!

Eruption Pollution Reaches Southwest Iceland By Eygló Svala Arnarsdóttir October 03, 2014 08:47 Updated: October 03, 2014 09:04

Sulfur dioxide (SO2) pollution from the Holuhraun eruption could be detected in Hvalfjörðyour, West Iceland, yesterday evening and in Norðlingaholt suburb of Reykjavík in the early afternoon. However, with maximum levels of 800 µg/m3 and 160 µg/m3, respectively, the pollution is much less severe than what it has been in North and East Iceland.

On Wednesday morning a record SO2 level of 5,800 µg/m3 was measured outside the school Reykjahlíðarskóli by Lake Mývatn in Northeast Iceland. The highest level until then was 4,000 µg/m3, measured in Reyðarfjörðyour, East Iceland, about one month ago, ruv.is reports.

At such high SO2 levels—above 2,000 µg/m3—people are advised to stay indoors.

The levels are based on a ten-minute average and they rarely remain high for long periods at a time. By Lake Mývatn on Wednesday, the SO2 levels had dropped again by the time the school started at 8:30 am and so teaching took place as usual.

Graphs showing SO2 pollution levels at different destinations around the country at each given time can be found on the website of the Environment Agency of Iceland (click on the dots on the map and then ‘more’).

The Icelandic Met Office publishes daily forecasts of the spread of SO2 gases from the Holuhraun eruption site with maps showing which areas will most likely be affected on each day and the following day.

Today, East Iceland is expected to be subjected to the most pollution from Öxarfjörðyour in the north to Höfn in the south. Tomorrow, a gas cloud is forecast to hang over North Iceland from Blönduós in the west to Öxarfjörðyour in the east.

Continued Seismicity at Bárðarbunga Volcano By Eygló Svala Arnarsdóttir October 03, 2014 09:32

Fifty earthquakes have been picked up by sensors around the Holuhraun eruption site since 7 pm yesterday, according to the Icelandic Met Office’s update this morning.

Most of the earthquakes have occurred in Bárðarbunga caldera and other in the northern part of the intrusive dike, channeling magma from the volcano to the fissure eruption in Holuhraun.

Seven earthquakes larger than magnitude 3.0 hit the northern part of Bárðarbunga caldera since yesterday evening, the strongest of which measured magnitude 4.8 and occurred at 1:41 am.

One minor earthquake of magnitude 2.4 hit at 9:57 yesterday evening 10.4 km (6.8 miles) southwest of Kópasker, Northeast Iceland.

hi allseasons

yes,looks to get higher every night or is it fountain fatigue lol

 

interesting read,you will need 5-10 mins though

Bardarbunga volcano update: no significant changes in ongoing eruption

Friday Oct 03, 2014 20:29 PM | BY: T

Eruptive activity at the Holuhraun fissure continues with little changes. Large amounts of lava continue to erupt from the active fissure vents. Lava fountains are now mostly hidden inside the growing cinder cones along the fissure.

SO2 gas output remains very significant - IMO estimates that 35,000 tons per day are being released each day into the atmosphere, producing a gas plume typically drifting eastwards and affecting air quality in eastern Iceland.                        #################################  

The caldera of Bardarbunga central volcano continues to subside at approx. 0.5 m per day, presumably as a result of magma draining from underneath there into the dyke, totaling more than 30 m so far - a process now often called "slow caldera collapse". Earthquake activity overall has decreased, but is still present under the northern extrusive dyke.

No one can predict the future development of this large and unusual eruption: The most likely scenarios are that 1) it might go on for a while to come, gradually decrease; 2) it could result in catastrophic collapse of the caldera with a resulting potentially large explosive eruption there; 3) it could open new eruptive fissures above the intrusion, possibly under the ice and cause large floods and ash emissions.

It could as well do something completely different. The next weeks to months will probably tell!

35,000 tons is significantly more than the 10-20,000 tons we were discussing yesterday. That puts it close to all of the US industrial output per day. Incredible for a fissure just a few hundred metres long.

hi yarmy

 

http://icelandreview.com/news/2014/09/25/holuhraun-emitting-more-so2-pollution-all-europe

 

the average is based on the time its been running

 

its said this has reached 60,000 tons per day

 

which is very high.

 

where we go from here is unknown but from looking at whats happening at present

 

i reckon we could see this going on for some time

[Allseasons-Si]

35.000 tons,is this in weight?

 

seems a lot

 

looking @latest models suggests to me that we MAY encounter S02 in the mix from the depression S of iceland making inroads to the NW of the BI from next week until saturday.

[Allseasons-Si]

i reckon we could see this going on for some time

It's been going on longer than i anticipated that's for sure!

 

did someone say,the longer this goes on the more chance of a eruption @ barda,can't remember who said that though.

 

might of been that jon f or the likes.

 

found him

Thanks John, where is this update from?

[Allseasons-Si]

Gps on the drop,let see what happens then,could be a big drop too.

 

 

what goes up,must come down,i sense a 4-5 mag again.

 

hekla taking the strain too!
