A new deep earthquake did just happen earlier tonight. The SIL system at IMO did give the earthquake the size ML1.7 with the depth of 22,5 km. In my experience this normally means that a earthquake swarm is about to start in Esjufjöll volcano. But this is not always the case, so we just have to wait and see what happens. But since earthquakes did start in Esjufjöll volcano last autumn (2010) with a earthquake swarm of about 70 earthquakes.
The activity has continues since then. But the earthquakes have completely stopped in-between earthquake swarms. This behaviour appears to be not uncommon in volcanoes in Iceland and elsewhere around the world. The earthquake yesterday in Esjufjöll volcano was size ML1.9 with the depth of 5.4 km. It is clear that a magma is creating this earthquakes, but there are few tectonics earthquakes in this area (but they do happen).
