During the night of 15-July-2017 a magnitude 3,1 earthquake took place in Krýsuvík volcano. This earthquake does not seems to be connected to the volcano it self, rather the tectonic forces that are common in the Reykjanes rift zone that runs in this area with many fault lines.
Other earthquakes that happened in this swarm had smaller magnitude. It also appears that this earthquake swarm is over. Earthquake swarm like this one are common in this area, it has been quiet for past few months and that is perfectly normal too, since last major earthquake activity happened in Krýsuvík in the year 2000 (several magnitude 5,0 earthquakes) and several magnitude 4,0 earthquakes in the year 2008 following major earthquake activity in SISZ.
Please remember to support my work. It helps me to keep working on this website and writing updates about activity in Iceland. Thanks for the support. 🙂
