Yesterdat (02-December-2020) at 11:38 UTC an small earthquake swarm started on Tjörnes Fracture Zone just south-east of Grímsey island. Largest earthquake in this swarm had a magnitude of Mw3,1. This earthquake swarm was small but there is also a strong snowstorm in Iceland and that has limited detection of earthquakes since late Monday (30-November-2020).

This is a different area from the area that had strongest earthquake swarm in 40 years on Tjörnes Fracture Zone in June 2020 when the largest earthquake had a magnitude of Mw6,0. It is difficult to know if there is going to be more earthquake activity in this area. There is always a risk that is going to happen.
