Deep earthquake swarm south-east of Bárðarbunga volcano

Since yesterday (18-July-2018) there has been a deep earthquake swarm south-east of Bárðarbunga volcano. Earthquake swarm in this location are common and due to their depth are always the result of magma injection into the crust in this area.

Most depth recorded in this earthquake swarm was 26,3 km and the shallowest was at 13,4 km depth. Error margin might be high in this location due to distance from SIL stations. Smaller earthquakes (magnitude 0,0 – 1,0) are harder to locate and give correct depth. Activity at this location is sometimes followed by a large earthquake in Bárðarbunga volcano (main). That doesn’t always happen. It is not possible to know if that is going to happen now.

    There it is! Green star: the caldera replied with a 3,4 m @ 2,2 km depth 18 hours after the swarm. 🙂
