An earthquake that measured M3,6 on the Richter scale occurred this morning at 5:07 AM, mbl.is reports. The earthquake was followed by ten smaller earthquakes. The largest quake was felt in Hof in the region of Öræfasveit, when most of the residents were asleep.
"It is the largest earthquake which has been detected in Öræfajökull, as the first measuring device was put in place at Kvísker in 1976. The quake was measured in the cauldron, around one kilometre southeast from the centre of the ice cauldron, which formed in the November of last year. There is some uncertainty about the depth of the quake, but it appears to have happened at a depth between 2-4 kilometers", a report from the Icelandic Meteorological Office read.
The Meteorological Office also mentioned in its report that there has been increased activity in the area for the last year or so. A noticeable increase has been evident since last fall, as two other earthquakes that registered above 3 on the Richter scale have occurred.
The area is currently heavily monitored as satellite images, along with planned survey flights, are used to assess surface changes in the glacier. The last satellite imagery was taken at the end of January.
The emergency colour for the area around Öræfajökull glacier will stay yellow, as the Meteorological Office will continue to monitor the area and assess the danger.
