Yesterday (7-September-2020) an earthquake swarm took place in Krýsuvík volcano early morning. The largest earthquake in this swarm had a magnitude of Mw3,3 and the second largest earthquake had a magnitude of Mw2,8. Other earthquakes where smaller in magnitude.
This earthquake activity is part of the inflation in volcanoes in the volcanoes in this area because of influx of magma at 3 km to 8 km depth. While no eruption has not yet happened that is the most likely outcome of all of this activity. When this enters the eruption phase is something that cannot be predicted.
