iceland Bárðarbunga and Askja - Volcanic Activity

[karyo]

At a depth of 1700m as well!

Yes, very shallow. I wonder. How it can keep producing those 5.2 earthquakes daily with no eruption

[frogesque]

Is it a case of the surrounding caldera rock is now so hot that there is plastic deformation and then slip? Not a good analogy but something like a sandcastle drying out and chunks falling off.

The Lava Keeps Getting Larger By Benedikt Jóhannesson September 28, 2014 10:38 Updated: September 28, 2014 10:56

The intensity of the volcano seems to be steady. A web cam shows the eruption from afar.

During the night, no significant changes were seen in earthquake activity. Last night, at 7.30 PM, an earthquake of magnitude 5.2 occurred at the northern rim of the Bárðarbunga caldera. The largest earthquakes during the night were in the northeastern part of the caldera, between 3.4 and 4.2 in magnitude. All in all, 16 quakes have been detected in Bárðarbunga from midnight, most at the northern caldera rim. Only five earthquakes have been detected under Dyngjujökull, the largest of magnitude 2.0. According to web cameras the intensity of the eruption is unchanged.

The lava is now over 44 square kilometers (17 square miles). The extent as estimated yesterday, based on radar images and observations in the field; area measurements since 26.9.2014. Little changes on the northern edge 27.9 (dark red line), no new information on the southern edge yet. The total area 26.9 was about 44,2 square kilometers, thereof the main field is 43.8 but the southern one 0.37. Vents and/or craters are marked with red triangles, see the trail on the southwestern end. The area covered by lava grows by almost two square kilometers per day.

You do have to wonder.... I have a feeling this could just fizzle out, or it would take a +6/7 quake to really get things moving.

its certainly not slowing according to this above

 

the bit thats interesting is the big quakes today have not caused any drop of the caldera

 

in my eye if the volcano is taking that pressure with no drops the pressure on it must be very high

 

imagine catching a cricket ball without pulling you hands back when you catch it..

 

remember this situation could go on and on and on

 

or the caldera could collapse or it could just stop

 

although the latter looks the least likely

at least we have a cam tonight

Hi John, my feeling is that this has been going for too long to just go back to sleep but I could be wrong. The webcam looks so good.this stunning combination of snow and lava!

[john pike]

cam looks stunning as noted by karyo

 

i do not see this stopping abruptly too

 

how it pans out is really a tricky one to call although

 

i feel expect the unexpected with this

if ecm is correct

 

from the 5th on expect to see more pollution heading our way

Let's hope we see some volcanic sunsets! :-)

Evening peeps

 

what stunning viewing from cam 1 this evening,wished i was there(for piccies only)

 

the gps is taking a tumble after a snooze fest for much of the day,could we see another biggy(EQ) coming up,or will it rebound,as again we await

 

 

oh,also just caught up with other activities around the world,hope there isn't any more casualties in japan,saw the clip of them trapped in that ash decent(pyro thingy),WOW

 

and on a final note that i wanted to ask the more knowledgable folk on here,are these cams constantly recording on barda in case this thing blows.

 

Edit:strange light flickering to the right of the fisure,is it scientist's or a new eruption about to take place!

Old news but found this!!!

a few 2+'s not verified yet though,one under the glacier(which is new) between barda and fissure @4.8km

 

gps dropping off again i think,too early to call.

hi allseasons

 

it looks like the mo are behind on updating but are quicker with the slightly bigger quakes at bara

 

thats why i follow the graph

 

 

you know its happened but have to wait for it to be confirmed

 

the thing noticeable is the increase in quakes at bara (smaller but more)

not sure about snow but looks a bit cold

[swebby]

Looking rather bleak and stormy there today.

 

... I'll try and post a screen grab once I've worked out why the editor will not let me paste one!.....

 

It looks to me that there may be some activity further up the dike where we had the minor eruption a couple of weeks back?  Possible steam, fumes but it could just be water interacting with the hot spot or pixilation on the cam.

yeap, they upgraded the earthquake to 5.5 which makes it the largest one to affect Bardarbunga in some time!

Edit: Steve, you are so fast!
