On Friday 22-January-2021 an earthquake swarm took place just east of Grindavík town. This earthquake activity then stopped but resumed at midnight on Sunday 24-January-2021. All of the earthquakes where small in magnitude and only few did go above magnitude Mw1,0 in size.

The earthquake swarm that started on Sunday lasted for 12 hours according to Icelandic Met Office website. There is no change in GPS location data (can be viewed here) and there is no change in harmonic tremor. Currently there is a bad weather in Iceland preventing automatic detection of small earthquakes all over Iceland.


I am currently in the process of closing down my PayPal account. Since using them is not cost effective for me at current time. It is possible to donate to my by using bank transfer. That is also more secure then using PayPal. The second reason why I do this is that I now have ads that help me with my income from this website. Since I need to get paid for my work some way. I have cancelled all regular donations that remained because of this. Thanks for the understanding and the support.

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.
