This is a short update on the earthquake swarm that is ongoing east of Grímsey island.
The earthquake swarm that started on 8-September-2022 east of Grímsey island is ongoing. Over 6000 earthquakes have been recorded at the writing of this article. Largest earthquakes in recent days have had a magnitude Mw4,2 and have been felt over a wide area. People living in Grímsey island and tourists in Grímsey island feel this earthquake swarm clearly.
There are no signs of an eruption is about to start. That might change without warning, but I don’t know likely an eruption is in this location because there’s no good data on possibility of an eruption. There’s also no clear reading from any nearby GPS station. This most likely is just an earthquake swarm. The risk of a magnitude 6 to 7 earthquake in this area remains high and such earthquakes can happen without warning.
