During the night of 6. June 2023 at 03:17 UTC an earthquake with magnitude of Mw3,0 at the depth of 15,8 km, took place close to Surtsey island. This was just a single earthquake and only one smaller earthquake with magnitude of Mw1,1 took place at 03:20 UTC, it is possible that few smaller earthquakes took place at this same location without having been recorded because of distance from seismometers that Icelandic Met Office has.
No other earthquakes have happened in this location today. This is just one off earthquake activity currently and I don’t expect that to change.
