A powerful earthquake swarm took place in the same region earlier this month. The area is highly active geologically, erupting on average twice each century. The last major earthquake swarms was detected in the region on April 10 and in February of this year and May 2015.

Monster volcano Katla trembles
At ten in the morning two strong magnitude 3 and 3.1 earthquakes were detected in the caldera of the giant volcano Katla. The epicenter of the quakes which took place just minutes apart, was in the middle of the caldera, just beneath the surface, at a depth of just 0.1 km (330 ft). 

The quakes this morning were not connected to geothermal activity, as some of the smaller quakes in the caldera. A geophysicist with the Icelandic Meteorological office told the Icelandic National Broadcasting Service that the volcano has been showing increasing activity in the past year.
