This is a short update of earthquake activity in Iceland on 28-February-2016.
Over the past 48 hours there has been earthquake activity and dyke activity in Bárðarbunga volcano. Some of this earthquake activity has been on around 15km depth. Suggesting magma movements within Bárðarbunga volcano system. Earthquake activity always seems to increase few hours to days after a swarm of deep earthquakes appear in Bárðarbunga volcano.
A dyke activity has appeared on the edge of Bárðarbunga volcano, it is located south-east in the volcano. In a area that has seen this type of dyke activity before. It is interesting that this activity seems to persist at this location.
Over the past few days few earthquakes have appeared in Tungnafellsjökull volcano. Some of those earthquakes have had the depth around 15 km. This suggest some type of magma movements inside the volcano, but nothing that suggests that its going to reach the surface any time soon.
Earlier this week (Week 08) an deep earthquake swarm took place in Askja volcano. With earthquakes having the depth down to around 22 km. Suggesting that magma is flowing into Askja volcano magma chamber at depth. This has been happening at regular basis since 2010. At the moment there is nothing suggesting that eruption is going to happen any time soon in Askja volcano.
There was some minor earthquake activity in Goðabunga in Katla volcano. This appears to be normal activity for this region of Katla volcano. No other interesting activity took place this week (Week 08) in Katla volcano.
Two earthquake where detected in Hekla volcano. Nothing else happened following this earthquake activity. Why this earthquake activity happens remains unclear.
