Location of today's earthquakes near Bardarbunga volcano
Earthquake epicenters since the beginning of the crisis (IMO)
The 10 km long tip of the dike now extends 5 km beyond the edge of the Dyngjujökull glacier. The entire dike is thought to be close to 35 km long and modelling of GPS data indicates that it contains about 300 million cubic meters of magma.

...25 Aug:
The seismic crisis in Bárðarbunga and Dyngjujökull continues strongly. Today alone, more than 400 quakes of magnitudes up to 4 were detected, mostly at the N end of the active intrusion that has been going on. The location of the quakes indicating the front of the magma intrusion (dyke) continues to advance northwards. Its tip is now outside the glacier and approaching the Askja caldera. In case of an eruption, it is now more likely that at least some of it occurs on land (and not under the glacier).
In total, the intrusion has a length of approx. 40 km. Horizontal displacement in the crust, based on GPS data, approaches 1 meter above the dyke. A rough estimation of the volume of intruded magma is about 1 cubic kilometers.

...24 Aug:
About half an hour ago, another strong earthquake (magnitude 5.3) occurred near Bardarbunga. It is not yet listed by IMO, but was already picked up by international earthquake monitoring systems.
...24 Aug:
The latest update from IMO mentions approx. 1300 earthquakes today (00-19:00) so far, mostly around the northernmost tip of the active dyke intrusion, now located 4 km north of Dyngjujökull.
More than 20 quakes were above magnitude 3, and the depths of most quakes were around 5-12 km. There is currently no sign of vertical magma movement and the propagation of the intrusion has slowed down compared to yesterday.

Stromboli (Eolian Islands, Italy): The lava flow continues to be active, but the effusion rate has been more and more unstable and fluctuates a lot. This results in lava flows taking different (often overlapping) paths on the upper portion of the Sciara del Fuoco. ... Read all

Volcanic activity worldwide 23 Aug 2014: Bárdarbunga volcano
Bárdarbunga (Iceland): Even if Bárðarbunga's eruption continues and breaks the ice, allowing explosions between magma and water/ice to eject significant amounts of ash, most experts agree that a scenario like the Eyjafjallajökull back in 2010 is unlikely to repeat itself. ... Read all
