Weekly Overview, 13 - 19. February, 2023

Around 370 earthquakes were detected last week by IMO‘s SIL seismic network, which is similar to last week when around 400 earthquakes were detected. The largest earthquke of the week on land was M3.5 near Herðubreið north of Vatnajökull Ice-cap. On 14th of November a earthquake swarm was detected about 200 km north of Iceland where 10 earthquakes between M2.3 and 3.6 were measured. Satellite images from the past week show that the ice covering Askja lake has been melting. Normally the ice melts in the summer between June and July, so this melting in February is quite unusual. A similar event was recorded in 2012 when the ice in Askja lake started to melt in March. More information on that event can be found in a news update here.
