There has been minor earthquake activity in Bárðarbunga volcano and Katla volcano for the past few days. This is just a short overview of this earthquake activity.
Bárðarbunga volcano
A minor dike intrusion took place in Bárðarbunga volcano on 18-June-2013. This was a small earthquake swarm, with largest magnitude at 1.2, the most depth in this earthquake swarm was at 24.3 km. So this was most likely a magma dike formation.

Katla volcano
A minor earthquake activity has been taking place in Katla volcano for the past few days. So far it does not mean anything, this is most likely a summer related earthquake activity as glacier weight gets less on Katla volcano during the summer. Some deep earthquakes have been taking place in Katla volcano, it is unclear if they are sign of anything at this stage. This is most likely a some magma dike intrusion at depth, it happens commonly in Katla volcano without resulting in a eruption.
