Earthquake swarm in Katla volcano

Today (15-December-2016) a minor earthquake swarm took place in Katla volcano. Largest earthquake in this swarm had the magnitude of 2,0. Other earthquakes where smaller in magnitude. Due to bad weather in Iceland at the moment the sensitivity of the SIL network is less than on a quiet wind day.

This earthquake started around 12 hours after the magnitude 3,4 earthquake that took place in Katla volcano yesterday. It is difficult to know for sure if those events are connected, that might be, but without some study into this swarm its a question that I don’t have an answer to. This earthquake swarm is located almost directly in Austmannsbunga in Katla volcano caldera (SIL station with the same name is close to this location). This earthquake swarm was not strong in magnitude of earthquakes, but it was considerable in number of earthquakes that happened in Katla volcano today.
