Increased seismic activity was detected in Mýrdalsjökull glacier in south Iceland, under which the volcano Katla lies, last night.
Twenty-six minor earthquakes were picked up by sensors, all of which had their epicenter within the Katla crater.
A seismic activity expert on watch at the Icelandic Meteorological Office informed ruv.is that the earthquake swarm had started at 1 am and continued through 5 am.
However, there is no reason to be concerned about an imminent volcanic eruption or glacial outburst in Katla. The earthquakes were all shallow and originated in seismic activity in the geothermal system.
