Bárdarbunga volcano news & activity updates

Bárdarbunga volcano update:

Map indicating all earthquakes that occured since 16 August, showing their spatial migration in the last 10 days (red = today)
The latest offical briefing from the Icelandic Met Office confirms that seismic activity continues to migrate northwards with earthquakes below Bárðarbunga becoming weaker. An eruption in the Bárdarbunga caldera is therefore at present considered to be less likely.

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.

At the moment, three scenarios are considered to be most likely:
- the migration of magma stops, which would be reflected in a gradual reduction of seismic activity.
- the dike reaches the ice-free surface near the current northern tip of the dike and initiates volcanic activity which is expected to mainly produce an effusive lava eruption.
- the dike reaches the surface where most of the fissure is beneath the Dyngjujökull glacier, resulting in an explosive, ash-producing eruption similar to the 2010 event at Eyjafjallajökull and causing floods in Jökulsá á Fjöllum.

Additional GPS monitoring stations will be installed north of Vonarskarð and on Urðarháls within the next few days.

Location of today's earthquakes near Bardarbunga volcano
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). ... read all

Earthquake epicenters since the beginning of the crisis (IMO)

Depth vs time of the recent earthquakes
Most Icelandic scientist now believe that no eruption occurred yesterday. The seismic activity in turn continues and has been stronger than ever today. ... read all

IMO believes that the two M5 earthquakes that took place under the caldera of Bárðarbunga volcano during the night were caused by adjustments in response to pressure changes in the plumbing / magma storage system of the volcano as magma is moving. ... read all
