Earthquake swarm detected under Bardarbunga volcano, Iceland


A swarm of earthquakes has been detected in the northern part of the Bardarbunga volcano caldera, Iceland on June 14, 2015. The sequence includes M4.9, the strongest quake detected since the end of Bardarbunga’s last eruption in 2015.

The swarm started with a M4.1 at 13:14 UTC on June 14 which was followed by several smaller earthquakes, the Icelandic Met Office reports. At 15:05 UTC, another earthquake with magnitude 4.9 occurred in the area as well as several smaller aftershocks.

The M4.9 quake is the largest earthquake since the end of Bardarbunga’s last eruption in 2015 along with another one of the same magnitude that occurred on January 30, 2018.

“No volcanic tremor is to be seen and the IMO is closely monitoring the situation,” the agency said.
