New earthquake swarm started in Tungafellsjökull volcano earlier today (13-January-2015). The earthquakes start at 13 km depth and go up to around 2 km depth far as I can tell.
I am having problems knowing at the moment if this earthquake swarm is growing or slowing down, at the moment however it appears to be steady in number of earthquakes taking place at the moment. Largest earthquake that has taken place in Tungafellsjökull volcano had the magnitude of 3,1. More strong earthquakes are to be expected. Some of this activity can be traced to Bárðarbunga volcano eruption and stress changes it is creating in nearby volcanoes. This is just half the story, since from the year 2013 there have been deep earthquakes (20 – 30 km depth) been taking place in Tungafellsjökull volcano. Suggesting that magma had already at that time started to move into the volcano at depth. It remains unclear if an eruption is going to take place in Tungafellsjökull volcano, it cannot be ruled out at this moment.
