Continued earthquake activity in Öræfajökull volcano

On 28 and 29th of September 2017 an earthquake activity took place in Öræfajökull volcano. Most of the earthquake that have happened are minor in magnitude, one magnitude 2,5 earthquake took place and on 29th September a magnitude 2,0 earthquake took place, this is automatic magnitude and might not be correct. The depth of this earthquake is the default one (1,1km).

It is extremely difficult to know what this earthquake activity means if it means anything at all. The reason being that this might be part of Öræfajökull volcano normal activity that is not going to result in a eruption. There currently is no way to know for sure what this means, since last eruption took place in the year 1728 and proper monitoring of Öræfajökull volcano only started few years ago. Current activity is however slightly above normal background activity that can be expected from a volcano like Öræfajökull volcano.
