This doesn’t look like an magma related earthquake swarm. This seems to be a fracture earthquake and might be connected to stress changes in the crust because of the high inflation in Svartsengi volcano, that is not far away from this location. The earthquake swarm is at a low now, but might increase again with stronger earthquakes without warning. If needed, I’ll post an update on what is happening.
