A powerful 4.1 magnitude earthquake shook Iceland's largest volcano early afternoon. At 14:18 (2:18 pm) the Seismic Monitoring System of the the Icelandic Meteorological Office detected the sharp quake 6.5 km (4 mi) east-southeast of the center of the caldera. Half a dozen smaller quakes have been detected in the giant sub-glacial volcano in the past 48 hours, according to IMO. The epicenter of the activity has been at a depth of only 1.1 km (0.7 mi).
Any quake in an active volcano which is larger than three on the Richter scale is considered a powerful quake. Quakes larger than 4 are relatively rare, and are associated with significant geological activity in the volcano.
Bárðarbunga, which is one of the most powerful volcanic systems in Iceland, is hidden beneath the north-western part of the ice cap of Vatnajökull glacier. Bárðarbunga has been showing significant signs of seismic activity since the end of the 2014-15 Holuhraun eruption. The activity is believed to be caused by the magma chambers of the giant sub-glacial volcano re-filling.
A number of powerful quakes have been detected in the caldera since the end of the Holuhraun eruption, but there are no signs of imminent volcanic activity.
