In the last 24 hours (20-January-2018) an earthquake swarm started in Tungnafellsjökull volcano. All earthquakes that have happened so far are small and no earthquakes have so far reached magnitude 1,0.
The earthquakes in Tungnafellsjökull volcano (red dots), north of Bárðarbunga volcano. Copyright of this image belongs to Icelandic Met Office.
At the moment there is nothing suggesting that magma is reaching the surface of this volcano. At the moment the earthquakes appear to be tectonic in nature. If they are due to influence of Bárðarbunga volcano (crustal stress changes) is unclear at the moment. Tungnafellsjökull volcano has not erupted in last 12.000 years and little data is on eruptions that are older than 12.000 years.

Two new articles today. One on Bárðarbunga volcano and the other on Reykjanes peninsula. They will be a bit late due to how my day has been.
