An earthquake swarm occurred under Mýrdalsjökull glacier between 10:50 and 11:20 am today. The strongest of the approximately 20 events was of a magnitude 3.1.
The Icelandic Met Office points out that the shallow earthquake activity is most likely linked to the hydrothermal system under the glacier and not unusual for this time of the year.
As reported earlier today, the level of uncertainty issued by the Civil Protection Department of the National Commissioner of the Icelandic Police last week because of a glacial outburst flood in the river Múlakvísl, which originates in Mýrdalsjökull glacier, has been lifted.
People are encouraged to continue to exercise caution in the area due to toxic gases still emerging from the flood water.
