An earthquake swarm at depths between 2-10 km about 8 km NE of Bardabunga volcano under the Vatnajökull icecap has started.
The swarm appears to contain relatively large quakes, including a magnitude 3.8 quake, which, if magmatic origin, could mean a shallow intrusion, that potentially could lead to an eruption.
