Series of Quakes Hit Katla Volcano in South Iceland

A series of earthquakes began in the sub-glacial volcano Katla in Mýrdalsjökull, south Iceland, shortly before 5 am this morning. Between 5 and 6 am 14 minor quakes were registered there, the strongest of which had the magnitude 1.6 points.

Between 6 and 8 am, six other minor quakes were picked up by the Icelandic Meteorological Office’s sensors, but after that the series subsided, visir.is reports.

Geographer Sigþrúður Ármannsdóttir at the Icelandic Meteorological Office, said the epicenter of the quakes were in the ice cauldrons that opened up during what probably was a minor eruption in Katla last summer, when the river Múlakvísl flooded, tearing a hole in the Ring Road.

Sigþrúður believes they were caused by geothermal activity. She added that increased conductivity that has been measured in Múlakvísl lately might indicate that geothermal water is leaking into it.

Approximately one month ago a small glacier outburst occurred in Katla which lasted a few days. Seismic activity in the volcano was picked up by sensors, as well as increased conductivity in Múlakvísl.

The reason was also believed to be increased geothermal activity in one of Katla’s craters.
