Evening my Bardabarians

 

Whoaaah!!!,24 EQ's over 3,she is bangin well again today,

 

i see more action NE of askja again too,latest news @ IMO mentions this

 

23 October 2014 10:00 - from geoscientist on duty

No significant changes are observed in the seismic activity around the Bárðarbunga volcanic system.

Around 70 earthquakes occurred on the Bárðarbunga caldera rim in the last 24 hours, the strongest events were magnitude 4.8 at yesterday at 13:21 and magnitude 4.6 at 01:36 this morning. All together 7 earthquakes exceeded magnitude 4 and 15 events were in the magnitude range 3-3.9. Subsidence of the caldera continuous. Two earthquakes of magnitude ~3.5-4.5 in Bárðarbunga just right now (09:48 and 09:50).

Around 30 events have been detected in the northern part of the dyke intrusion, between northern Dyngjujökull and the eruption site in Holuhraun. The strongest were both magnitude 1.4 yesterday at 10:07 and 13:33.

A magnitude 3.0 earthquake occurred southeast of Herðubreið yesterday afternoon at 17:04, around 10 smaller events have preceded and followed this event. The region around Herðubreið and Herðubreiðartögl has been moderately active in recent days. Although this activity might be a response to increased stress due to the dyke intrusion, the region has been frequently active in the past and a direct link between the intrusion and the present activity is not obvious. No activity was observed under Tungnafellsjökull.

The last visual observation of the eruption was around 05:45 this morning.

Mainly between 7 and 10km deep with the odd shallower quakes all high 3 to 4 level intensity

[Freddie123]

Seems to have been quite a change to the EQs in recent days. Any theory's from those here more knowledgeable that me on what is happening?

[karyo]

M5 just happened in Barda!

 

I think there must be a new injection of magma from a great depth but I am not an expert.

 

Karyo

[SteveB]

Plenty of quakes around the 8-10km depth, that must be 20-30 over 3 in the last couple of days.

24.10.2014 10:20:41 64.676 -17.479 8.6 km 4.8 99.0 4.6 km NNE of Bárðarbunga

The 5 and a few others within a 10 minute window others around 10km down whereas the 5 was 2.9km down

[Rustynailer]

In my opinion this is harmonic tremor at a mag 3/4 sort of level. Looks dangerous as hell.

Indeed. This along with its position on the mid-Atlantic ridge is the reason Iceland exists at all.

hard to see but a lot of light there at present

I think it is the brightness of the lava in the low cloud but I could be wrong. Either way, the fissure still looks lively!

it looked like a lot of light on the cam behind the fissure

 

but as you say karyo

 

probably the lava refecting in the cloud

 

the fissure has certainly picked up again

Just looked at http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/
