I am still trying to understand what is happening here but there does seem to be a little confusing information going on. Before I express any thoughts, understand that I am not a volcanologist and th

Did you see the beautiful picture with the eruption glow and northern lights giving surreal lighting effects.   The eruption seen from Jökulsarlón south of Vatnajökull glacier.  (Martin Schultz,

This is my favourite (from elsewhere) to date - very atmospheric.

we should be able to trust it as its at 99 so been reviewed

 

 

The default depth for uncertainty is 0.1 at 99% it means as yet depth uncertain @ IMO

 

Todays quake map is a busy one alright.

hi rusty

 

give or take 1% in my eyes is as good as checked

 

granted its been said they are not confirming these as perfect due to being busy

 

and today is certainly one of them days

19 up to 15.36 so no slow down from yesterday

 

12,8 depth and the 10.8km depth is very deep

 

a very shallow 0.3 km depth too

New Holuhraun Lava Field Keeps Expanding By Eygló Svala Arnarsdóttir November 18, 2014 08:36

holuhraun_eruption_sun.jpg?itok=tBQ7mqkz

The new Holuhraun lava field. Photo: Geir Ólafsson.

The volcanic eruption in Holuhraun continues with similar intensity as it has for the last two weeks. Lava continues to flow out of the lava lake in the crater to the east-southeast. The lava field now measures approximately 72 square km (28 square miles).

The new lava is now twice the size of Mývatn in Northeast Iceland, the country’s fourth largest lake, RÚV reports.

Seismic activity in Bárðarbunga volcano under Vatnajökull glacier continues to be strong. In total 160 earthquakes were detected in the area since noon on Friday, two of which were magnitude 5.4, as stated in the latest update from the Scientific Advisory Board of the Icelandic Civil Protection, released at noon yesterday.

The subsidence of the Bárðarbunga caldera continues at a similar rate as in the last few weeks. The rate of the depression in the center of the caldera is decreasing but the flow of magma underneath the caldera is not since the depression area in the caldera continues to grow at the same rate as in the past three months.  

GPS measurements outside Bárðarbunga show that the displacement is slowing down.

Three future scenarios are still considered most likely: that the activity will gradually subside and the eruption in Holuhraun stop; that the fissure will extend under the glacier and result in a sub-glacial eruption, ash fall and flood; or that Bárðarbunga will burst with a major sub-glacial eruption, ash-producing activity and massive flooding in glacial rivers.

Eruption pollution is expected to the north and east of the eruption site today and tomorrow. Forecasts are available on vedur.is and information on sulfur dioxide (SO2) levels and advice on how to respond to the pollution on airquality.is.

Morning Bunga's :D

 

latest news from IMO

 

19 November 2014 10:00 - from geoscientist on duty

No significant changes were observed during the last 24 hours in seismic activity at Bárðarbunga and in the dyke intrusion, as well as in the volcanic activity at the eruption site in Holuhraun.

The strongest earthquakes at Bárðarbunga were M4.6 yesterday at 18:21 and last night at 00:29, both on the northern caldera rim. Five additional events were larger than M4 and 18 between M3 and M3.9. All together around 80 events were detected in this region. None of the approximately 10 earthquakes detected in the dyke intrusion exceeded M1.5.

A M3.1 earthquake was detected in Tungnafellsjökull yesterday evening at 18:56, around 10 smaller events have followed. Similar small bursts of seismic activity have repeatedly occurred in Tungnafellsjökull since the beginning of the Bárðarbunga activity.

Based on camera observations the eruption in Holuhraun is continuing at similar force as during recent days, no changes were reported from scientists in the field.

If you also look at what john posted above there seems to have been an increase in the 3+ quakes that are very shallow especially in the NE / NNE/ ENE quadrant.

I wonder if this is the final weakening occuring before that flank collapses and we go bang!!!

 If that is real is is likely to be dangerous....Never seen this before, Hekla erupts without shaking for ages beforehand, just couple EQ's then eruption usually...post-4726-0-97891200-1416477959_thumb.jp

 

 

IMO correction now a 0.9 ....  People in Iceland are relived that "the gateway to hell" remains shut for now.  post-4726-0-84955700-1416478433_thumb.jp

 

Still noteworthy as Hekla does not shake... 

 

This is possibly a rifting stress re adjustment or the like, Badabunga eruption and rift will effect the stress fields of all Iceland.

Thermal images of the craters
hitamynd_18112014.pnghitamynd_23092014.png
Thermal images (FLIR) of the craters, seen from the west (hence N to the left and S to the right).
The upper image is taken recently, 18 November 2014 at 16:00. Now, thermal convection is greatest from the northern part, Heimasæta, and the temperature is somewhere in the range 1147-1188°C.
The lower image was taken 23 October 2014. Then, craters Baugur and Heimasæta were both active. Institute of Earth Sciences, information from the field group.
