Weekly overview, 15. – 22. November - week 46.

About 12000 earthquakes were detected last week by the IMO's SIL system of which about 1350 earthquakes have been manually reviewed. Continued seismic swarm due to a dike intrusion that formed on the 10 November. The seismicity and magma inflow to the dike has however reduced. it should however be noted that the magma inflow to the dike could still be greater than prior to the eruption in Fagradalsfjall in 2021. Uplift resumed in Svartsengi after the dike formed and is faster than in previous uplift. The largest earthquake of the week was a M3.7 located about 3 km west of Klefiarvatn.
