While this earthquake swarm in Krísuvík volcano does not appear to be big in size. It is clear that was rather long and might even be ongoing. But it is interesting how long this earthquake swarm did last. So far the time is about 2 days. It is impossible to know if the earthquake swarm is over or not. Current number of earthquakes is about 60 earthquakes so far.
The earthquakes are on North-South fault line according to the visual evidence. Depth of the earthquakes is from 12 km and up to 3 km at the moment. It is hard to know at the moment if this is due to magma inflow under Krísuvík volcano or just normal tectonic activity along the rift zone in Reykjanes.
