At 21:10 UTC a earthquake swarm started in Tjörnes Fracture Zone just north of Gögurtá. Largest earthquake so far had a magnitude of 3,7. Other earthquakes so far have been smaller in magnitude so far. That might change without warning.
There is some mislocation on the map at the moment due to the automatic location system at Icelandic Met Office website.
Since my geophone at Böðvarshólar is down due to a failed computer and I cannot afford Raspberry shake sensor (weatherproof type) only the largest earthquakes are going to be recorded at Dellukot geophone.
