Magnitude 3,7 earthquake in Bárðarbunga volcano

Today (16-May-2014) a magnitude 3,7 earthquake took place in Bárðarbunga volcano. The source of this earthquake is not clear, but this appears to be a magma injection into Bárðarbunga volcano. Such events do happen in Bárðarbunga volcano without starting an eruption.

There was around 20 aftershocks following this earthquake. Largest automatic magnitude was 2,6, but strongest reviewed earthquake activity so far had the magnitude of 2,5. More earthquake activity is most likely going to continue in this area. Earthquakes with this or stronger magnitude cannot be ruled out from happening. There is currently nothing suggesting that this is other then just normal earthquake activity in Bárðarbunga volcano.
