Yesterday (23-August-2018) an fresh earthquake swarm started in Öræfajökull volcano. This earthquake swarm seems to be progressing in the same way as earlier earthquake swarms. Earthquake activity in Öræfajökull volcano only happens when magma is on the move inside the volcano.
Largest earthquake in this swarm had a magnitude of 2,2 and the second largest earthquake had a magnitude of 1,9. Other earthquake activity has been as before and is mostly made of earthquake with magnitude 0,0 and up to magnitude 1,0. The magma in Öræfajökull volcano is slow moving and that is reflected in current earthquake activity.
