Earthquake swarm, possible subglacial eruption at Bárdarbunga volcano in Iceland

Earthquakes under Bárdabunga volcano

Harmonic tremor (Dyngjuháls SIL station, IMO)

An intense earthquake swarm started yesterday under Bárðarbunga volcano, located under the northwestern part of the Vatnajökull ice cap. It is continuing at the moment and accompanied by elevated harmonic tremor.

This might indicate a subglacial eruption at the volcano, but this needs yet to be confirmed.

The last eruption of Bárðarbunga volcano was in 1797, while another eruption in 1910 took place at neighboring Hamarinn volcano.
