During the night of 25. November 2023 at 03:42 UTC an earthquake swarm took place just west of Kleifarvatn lake. Largest of this earthquake had a magnitude of Mw3,0. This earthquake swarm is a tension breaking earthquake swarm connected to the inflation in Svartsengi and the formation of the dyke under Grindavík. There’s going to be a lot of this type of earthquakes all over Reykjanes peninsula and on Reykjanes ridge in next few months.
