The Icelandic Meteorological Office’s SIL earthquake monitoring system picked up approximately 1,300 tremors in Iceland this past November, the largest of which measured 3.5 on the Richter scale and hit the Katla caldera on November 8.

Most of the earthquakes last month had their epicenter below the Mýrdalsjökull icecap, which covers the volcano Katla, and by Húsmúli on Hellisheiði where Reykjavík Energy is based; the seismic activity there is caused by geothermal boreholes, Morgunblaðið reports.
A series of minor earthquakes occurred on Hellisheiði 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, Hellisheiði 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.
