Today (18-June-2017) an earthquake swarm took place in Katla volcano. Largest earthquake in this swarm had the magnitude of 3,2 and the second largest earthquake had the magnitude of 2,8 (two earthquakes). Depth was registered at 0,0 km. That means it was below the error margin Icelandic Met Office has, that error margin is around 300 meters +-.

This earthquake swarm was close to being directly in north-south direction. At the moment the earthquake activity has gone back to background levels and no other activity appears to be taking place at the moment. I don’t know yet if this earthquake swarm activity is part of the normal summer earthquake activity or something else happening. Only time is going to make that clear.
