Bárdarbunga volcano news & activity updates
Bárdarbunga volcano update:

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.
Earthquake epicenters since the beginning of the crisis (IMO)
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.
The earthquakes under the caldera are believed to be a result of magma draining from the central reservoir underneath horizontally into the new dyke.
(Note: A dyke can be imagined as a fissure where magma intrudes at depth - pathways of magma inside the crust).

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
