Minor earthquake swarm in Katla volcano

During last night (21-February-2015) a magnitude 3,3 earthquake took place in Katla volcano. This was a shallow earthquake and took place close to the area that had minor eruption in July-1999.

Second swarm of earthquake also started today in the east part of the caldera in Katla volcano. This is not far from the location the had a minor eruption in July-2011. Most of the earthquakes that took place at that location where deep, with the deepest earthquake having the depth of 19,9 km. At this depth earthquakes happened due to magma pressure changes. There is a chance this was a minor dyke intrusion at depth in Katla volcano magma chamber, no harmonic tremor was detected following this earthquake activity. At this moment there is nothing suggesting that anything is about to happen in Katla volcano at current time.
