A 4.7 magnitude earthquake hit 4 km (2.5 miles) southeast of Bárðarbunga volcano in Vatnajökull glacier, southeast Iceland, shortly after midnight last night. It’s the biggest earthquake to have hit in the area since the current seismic activity began there last Saturday.
According to the Icelandic Met Office there are no indications that magma is about to break its way to the surface, mbl.is reports.
More than 2,100 earthquakes have been picked up by sensors in Vatnajökull in the past 48 hours. The seismic activity continues, although the area is rather quiet at the moment.
Earth scientists believe that a tunnel has formed in a crack extending from the southwest to the northeast in Dyngjujökull outlet glacier on the northern border of Vatnajökull.
