Jök­ulsá á Fjöll­um.

Icelandic Co­astgu­ar­d's airpla­ne land­ed at Reykja­vik airport tonig­ht. On bo­ard the pla­ne were geolog­ists ret­urn­ing from their flig­ht over Bárðarbunga, among­st them Magnús Tumi Guðmunds­son, one of Iceland's lea­ding geop­h­ysicist.

"The flig­ht went well, we mana­ged to gat­her the in­formati­on we wan­ted. We did radar mea­surements of the glacier and the ri­ver Jök­ulsá á Fjöll­um, which will be of much value in the event of an erupti­on," he said in a telepho­ne in­terview with mbl.is.

Magnús says it's hard to evalua­te the chances of an erupti­on. "It can go eit­her way, no­bo­dy can really predict what will happ­en in this situati­on."

there might be nothing wrong with those pics john you can get bright lights near places of seismic activity or volcanic activity

 with subvertical (nearly vertical) faults in rifting environments having the most incidences of earthquake lights

Bárðarbunga Volcano Watch: The Morning Edition

Bárðarbunga volcano continues to rumble but as yet there is no eruption to report, so here is a round up last night’s news.

The Pressure under the ice must be phenomenal, depending on where it could erupt there is between 500 and 700 metres of ice ABOVE the eruption so between 500 and 700 tonnes per square metre

 

Incredible

[Tom Jarvis]

Wow 3 quakes above mag 3. One a 4.0m at 3.1km and a 3.7m at 2.7km. Looks like things are hotting up

[john pike]

Mag 4 and a 3.7 recently at barabunga and shallow

Sorry tom :-)

[Tom Jarvis]

Yes jp looks like it could go bang soon also lots of vents on the live cam producing steam. Would you now say something is going to happen there soon??

[john pike]

Hi tom

A few more 4 plus quakes would make things more likely sooner

But this could go on for a while still while the magma tries to find a way

Through the ice

Still a watch mate for now

[Tom Jarvis]

Another 3.5m earthquake at 4km now let me gess lava is stil flowing into the chamber

Whilst everyone is waiting for Iceland to blow up.

Ok possibly a naive question from someone who doesn't know.

If Stomboli is in almost constant eruption why is the island relatively small?

Because it doesn't produce very much material. Basically they are gas explosions ejecting small amounts of relatively viscous material with rare lava flows.

its all to do with its output even though it is constantly erupting its eruptions tend to be smaller in size so doesn't grow the island at a huge rate plus in overall timescale 2000 years of eruptions isn't that long in volcanic timescale another couple of hundreds of thousands of years and there will be a sizable island there

 

ah see I was beat to it lol

Very interesting update from Jon Freeman. The caldera is showing sign of lowering!

Lol just saw the webcam on this page shake quite a lot for a few seconds.. unless someone is up there wobbling it.

Hang on.. just saw there's a tick box called 'shake webcam on updates'.. doh 

wasn't properly paying attention to it.

Stromboli volcano (Eolian Islands, Italy): strongly fluctuating effusion rates at lava flow on the Sciara del Fuoco

Surge in lava supply at Stromboli this morning caused formation of new channels

Decreasing effusion rate this afternoon lets the channels almost "fall dry"

Lava continues to flow from the fissure vent at the base of the NE crater. Compared to the first week, the effusion rate has become more unstable, causing several surges and intervals of strongly decreasing activity. The fluctuating rate of effusion has also caused the formation of several overlapping new lava channels in the upper area of the Sciara. Two such surges occurred yesterday and today. This can be seen in the time-lapse video below:

bardarbunga eruption checker currently its no but if that changes to I think YA then its erupting

Basically saying if it happens it should be a big event....very interesting indeed.

21.8.2014

Yesterday, two IMO staff members took part in a flight to Bárðarbunga and along the river Jökulsá á Fjöllum in the aircraft TF-SIF from the Icelandic Coast Guard. The onboard SAR-radar was used to image the glacier and the river.

Although it turned out to be cloudy and the visibility impaired, the radar imaging was successful. If the present seismic activity in Bárðarbunga leads to an eruption and consequently a glacial outburst flood (jökulhlaup), these images will become an important dataset for estimating the changes which may occur on the glacier and on the flooded area.

 The photos below were taken by Halldór Björnsson:

Fig. 1

View to the south across Bárðarbunga. Grímsvötn to the left and Köldukvíslarjökull in the foreground.

Fig. 2

View to the north over the two cauldrons Skaftárkatlar. The western cauldron is visible to the left. The eastern cauldron is hardly visible to the right. If and when water will be released from underneath that cauldron, it will become more visible again.

Fig. 3

Estuary of river Jökulsá á Fjöllum in Axarfjörðyour, North Iceland. The small lake to the right is Skjálftavatn, which was formed as a consequence of the prolonged Krafla eruptive phase 1975-1985. Only a small ridge separates the lake from the river.

Fig. 4

This is where the cirle road around Iceland, road nr. 1, crosses river Jökulsá á Fjöllum, not far from farm Grímsstaðir á Fjöllum. This bridge might come under severe strain if the Bárðarbunga seismic phase leads to an eruption and a glacial outburst flood: A grave concern for the Icelandic Road and Coastal Administration. Just south of this bridge is a closed area for safety reasons.
