Most of the earthquakes last month had their epicenter below the Mżrdalsjökull icecap, which covers the volcano Katla, and by Hśsmśli on Hellisheiši where Reykjavķk Energy is based; the seismic activity there is caused by geothermal boreholes, Morgunblašiš reports.
A series of minor earthquakes occurred on Hellisheiši on Monday night this week. Around 20 tremors were picked up by sensors, the largest of which was close to two points on the Richter scale. Otherwise, Hellisheiši has been quiet lately.
So has Katla, which is being closely observed due to increased seismic activity, volcanic eruption concerns caused by the lighting equipment used by the film crew of Game of Thrones last week aside.
