Yesterday (27-January-2021) an earthquake swarm started in Prestahnúkar volcano. Largest earthquake in this swarm had a magnitude of Mw3,0 and other earthquakes where smaller in magnitude.
This earthquake swarm has stopped but it might start again since earthquake activity in this area is often slow to start and goes on for a long time, up to 1 to 3 years. There is no sign that magma is at work in this earthquake swarm.
