Interesting developments, I think the fissure eruption has died down somewhat now. It will probably be up and down now gradually getting bigger. Or if it stops it may build up pressure and pop out elsewhere, we will see.

Bada is still in danger of caldera movement and or collapse, Askja is also not what I would say normal she is stressed.... The quakes continue, though the wind makes all but the big ones hard to isolate on a chart, so the IMO won't bother, they are not daft that's what always happens.

The web cams will be dirtied by the incoming storm and no doubt we will have to wait for cable guy to trundle up the mountain and refresh them after the "weather episode" is over.

Great fun, main thing to watch are big quakes at Bada, Askja and the fissure, quakes that show up large and correlated 99% on the fissure its self usually means a change ,i pressure or a blockage.

When in bad weather all we will have are the graphs charts and brave scientists at the fissure posting on face book, no webcams, we are so spoiled by facility's in 2014  . 

This will be probably the best Internet eruption on the Internet in the history of the Internet up to know, ground breaking.

The first drone flights are being talked about as we post.....

One more thing, this is an Icelandic eruption, expect the unexpected.

 

The wind is starting to take effect I think, but also there may have been a larger quake just after mid day here 11:00 over there.

 

The fissure is still erupting now 11;37 Iceland time.

 

I wonder is anything happening NE of Askja?.....File No 4

thanks for the lava composition.

 

edit if this blows ex Christobol going to spread it far and wide.  That camera really moving not sure all wind causing it

According to John Freeman the stormy conditions mean that fewer earthquakes are going to be detected due the wind noise.

Also, the progress of the dyke towards Askja appears to have stopped and he doesn't know why that is (although that was written before the current eruption which may explain the lack of progress).

Due to the impending stormy conditions, I was also asking myself that same question, how will the winds affect the volcano eruptions and it's associated earthquakes. Fascinating stuff and as you stated I suspect our own Met Office may well be watching things closely as to how the situation evolves synoptically in say, four to five days. 

 

And then there is all the forecast rain, could that cause additional landslips?

Scientists believe the #Holuhraun #eruption started around 0400. Lava is flowing at around 1000 m3/s and is 1kmx3km wide. Still ongoing.

Thanks John and also for those other links, same goes to the other guys n gals. 

 

I see it does mention mudslides, could get interesting. Are there any villages in the way of all this mayhem (although fun for us to watch)?

It is a possibility but don't forget that Iceland gets stormy spells like this one quite often in the late summer/early autumn.

Good point karyo.

According to this, tomorrow's wind strength will be quite reduced (around 15 miles/hour) so it should be a better day for checking the earthquake activity.

4.8 earthquake reported 

[lorenzo]

Bárðarbunga cam 2 looking great just now getting buffeted a lot by the wind too, good when it zooms in..

 

Fair to say it's all going off in Iceland, esp with ex - Cristobal bombing in at 964 / 967mb..!

I'm placing this to be under the caldera, please say if this is wrong.  A lot of activity around the caldera this morning, if there is an on-going eruption there and we get a jokulhaup as a result, which direction is it likely to take?  I'm asking as I'm wondering if the current fissure eruption is on the flood plain?  Glacial flood meets fissure eruption - what could go wrong there......

 

 

Edit - from this http://en.vedur.is/hydrology/articles/nr/2963 it looks as if the fissure is indeed on the flood plain.

 

An ex-hurricane, a volcanic eruption and if we have a glacial flood is there anything left that mother nature could throw at Iceland?

Looks like a build up then...

That's impressive and goes with what Jon Freeman said yesterday that the possibility for Bardarbunga to erupt has increased!

[Evening thunder]

There definitely seems to be an increasing concentration of quakes NE of Askja, starting to look similar in activity as the main dyke, but extends less deep. Shows both on the Icelandic Met pages e.g http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/ and the 3D site (http://baering.github.io/)

 

Maybe another intrusion, possibly allowed to occur in response to stress changes from the main dyke?
