  1. The inhabitants of Grimsey must be tired today, after all the rumbling during the night.

    By the way, thanks for bringing back this comment function!

    1. It was in the news today that people in Grímsey island are indeed tired of this earthquake activity. Not because of this earthquake swarm but rather the fact this earthquake activity has now been going on for months as it started in western part of Tjörnes Fracture Zone on 19-June-2020 and has been ongoing since.

      The comment where available for people with registered accounts. But I continue to have problems with spam registration so I disabled the registration again and just opened up the comments. It was just easier than trying to figure out how to block spam registration on my website.

      I was trying to stop the occasional comment that told me to stop asking for donations because that was somehow begging in their view. Both here and the Icelandic version of this website (at so that comment was made by some annoyed Icelander that hates my work here.
