Early morning (14-April-2021) an earthquake swarm took place far north of Kolbeinsey island. Largest recorded earthquake had a magnitude of Mw3,5 but it possibly was larger but because of distance from the SIL network the magnitude is underestimated. I did record this earthquake on my only seismometers and it showed a lot of surface wave activity, suggesting a larger magnitude than Mw3,5.
Because of remote location of this earthquake swarm it is not possible to know what is going on there. The area is also under an ocean that is 2 to 4 km deep at this location. If anything happens it is not going to be noticed outside of being detected with seismometers.
