iceland Bárðarbunga and Askja - Volcanic Activity

[Allseasons-Si]

Evening all

 

nice to see the eruption site again,so she still goes on,+a lot of big quakes again today i see

 

as for the gps @ the moment,there is no data but still updating

 

i have drawn a black circle where it is blank,hopefully it will be back up and running soon.

 

 

incoming

 

m4+ maybe

 

 

quiet a few upticks on here

I don't like it when they get downgraded.

[Allseasons-Si]

I don't like it when they get downgraded.

No neither do i,it said 99.0% as well on IMO.

 

A 2.7 @ the edge of the glacier allthough quiet deep,but theres not been much activity in that area in the last 48 hrs

not bar 1 WSW

 

all have been north-north east

 

 

 

looking at the above

 

the ground is being displaced east to west and north east to south east

 

with the pressure of the quakes to the north east and the subsidence not so noticeable now

 

(except for the 4th with the mag 5 ). i still feel the north east flank is at risk of collapse

 

however this again are my own opinions and in theory this could just stop.

 

 mo update

 

6th October 2014 19:00 - from geoscientist on duty

Seismic activity in the dyke intrusion was low today, see today's map (and compare to a week ago). Since 07:00 this morning, only about 5 earthquakes have been detected there (less than 10 since midnight), all below magnitude 2. Storm conditions around Vatnajökull might affect the detection of the smallest earthquakes.

Around 20 earthquakes have been detected around the Bárðarbunga caldera rim since the last report at 07:00 (ca. 30 since midnight). The strongest event was magnitude 5.1 at 11:04 on the northern caldera rim. Of these, seven events exceeded magnitude 3 (ten since midnight).

The visibility of the eruption at Holuhraun on the webcams was limited today. Scientists in the field, and the ranger in Dreki, have confirmed that it is continuing at comparable levels as during recent days.

the plots now show the 4,7 quake

 

look to be around 40 mins behind

Yeah

 

dyn and grim picked it up first while von was behind.

up again

up again

Grims is on the up too i think!

 

[Allseasons-Si]

Gps trying there

 

http://hraun.vedur.is/ja/Bardarb/BARC/

 

look at that drop lol

 

that would be substantial,but i think that is not right and we should give it time to re-adjust.

 

now a big rise lol.

 

Edited October 6, 2014 by Allseasons-si

[Allseasons-Si]

A 3+ coming soon

 

uptick there

 

 

maybe toutching a 4.

 

guess 3.8

 

well,gps is still up and sticking there  @ the mo,that's quiet a jump,i will give it a bit longer to see if it levels out,if not,then there is something happening.

Same thing happened at midnight the previous 2 nights. Some sort of scheduled instrument recalibration?

Yeah,but this looks diferent though,maybe give it a bit more time but it's holding up there  @ the mo

 

maybe or maybe not something is happening,i have that funny feeling lol.

[The PIT]

Fairly quiet overnight. Nothing too see on web cams due to the weather no doubt.

[Midlands Ice Age]

See there has been a mag 5.0 and a 4.0 overnight.

Also quite a few near surface smaller quakes which have not yet been shown on the GPS map yet.

The GPS signal seems to be trying to settle down after yesterday's evening outage but somehow it looks slightly different to me. It seems to be trying to rise a small amount.

What has caught my eye is the large drop in the GPS between 3 and 6am!

[BrickFielder]

  Just a quick note to say I think something a little different happened overnight. Bearing in mind the weather conditions are poor in the area of Bárðarbunga and there is ample reason to see false signals I still think something a little different happened.

 

 

These measurements are a cooperation of the University of Iceland, the Icelandic Met Office, the Civil Protection department of the NCIP and the Icelandic Coastal Survey. They are accessed through the Icelandic Met Office web site at the following address.

 

http://en.vedur.is/earthquakes-and-volcanism/gps-measurements/bardarbunga/caldera/

 

 

 

It looks like there was a slight uplift and then a marked drop at Bárðarbunga. We have seen this a number of times before so at first glance nothing seems unusual. There has even been speculation that this bumping around is something to do with how the ice reacts in the caldera.

 

What strikes me as different is that this appears to be picked up on other SIL's. These are extracts from the full SIL charts.

 

 

 

The full charts are accesible at the university of Iceland site at the following link

 

http://jardvis.hi.is/gps_timaradir_vid_bardarbungu

 

 

This looks like a marked eastwards movement at vonaskard (VON SIL) with a smaller movement eastwards at  HAFS, while there appears to be a movement westward at DYNC. Bearing in mind weather conditions (blue lines on tremor charts tend to pick up) there does not seem like much evidence in a pick up in magma movement near the surface (red and green lines on the tremor charts).

 

A possible culprit is the following earthquake Monday Evening

 

06.10.2014    22:00:20    64.677    -17.410    4.0 km    3.8    99.0    6.9 km NE of Bárðarbunga.

 

To me this looks more like a slip fault earthquake on the ring fault. Something a little different from the normal even if it is not. I think this shows how the crust is being deformed and this might just be a relaxation in stress. I would not be surprised to see earthquake activity reduce a little now and for the eruption site to see a little spurt of activity through this morning.

 

As usual this is my interpretation and may well be wrong so make up your own minds.
