Yesterday (24-January-2021) at 09:16 UTC an earthquake with magnitude Mw3,1 took place in Kolbeinsey island. Two unconfirmed earthquakes with magnitude of Mw2,5 and Mw2,6 took place at 17:37 UTC and 19:06 UTC.
The area is remote and it is difficult to know if there has been any more earthquake activity there. There is also a storm going on and has been going on for last several days and that limits detection of small and remote earthquakes in Iceland.
