There was a small earthquake at 23:50 UTC in the Torfafjökull volcano. The earthquake it self was only ML1.7 in size, but the depth was 15 km. But that depth indicates that the earthquake was started by magma rather then tectonic process in the area. This would mean that a dike intrusion was starting in Torfajökull volcano at present time.
I did record this earthquake on my geophone, but this earthquake had a magma looking signature in it. But it was not clear and hard to see due to a minor weather effect in the area. Torfajökull volcano is not monitored with GPS instruments at the moment.
This is unlikely to be a pre-event to a eruption in the area. But dike intrusions appears to be a common events in Torfajökull volcano.
