This morning (4-March-2019) a strong earthquake swarm took place in Bárðarbunga volcano. Largest earthquake had a magnitude of 4,1 (at 05:52 UTC), second largest had a magnitude of 3,8 (at 05:46 UTC) and the third largest earthquake had a magnitude of 3,3 (at 06:03 UTC). Other earthquakes were smaller in magnitude.
Total of eight earthquakes where recorded in this swarm. This earthquake swarm is slightly unusual because its only been two weeks since a magnitude 4,2 earthquake took place in Bárðarbunga volcano. This are inflation related earthquakes, since Bárðarbunga volcano has been inflating since end of the eruption in Holuhraun in February 2015. This process is going to continue until next eruption happens in Bárðarbunga volcano system. This process can be at shortest be 1 year and at the longest this can take 104 years. I base this on Bárðarbunga volcano known eruption history. Details can be found in Global Volcanism Program information website about Bárðarbunga volcano.
