Today (15-December-2019) an earthquake swarm started this morning at 07:10 UTC and the strongest earthquake had a magnitude of Mw3,5 and other earthquakes have been smaller in magnitude. Around of 190 earthquakes have happened in this earthquake swarm that appears to be over or at least has stopped for now.

This is a tectonic earthquake swarm from the looks of the earthquakes that I have recorded on my geophone. This is probably a rift valley activity in this area. It is not possible to know if this earthquake activity is over or not. It is common that earthquake activity stops for few hours and then resumes at higher activity then before. Sometimes this type of earthquake swarm just stops and doesn’t resume.


Please remember to support my work with donations. I am really broke this month and that has started to create problems for me. If you support me by donating with a bank transfer please update your information since I now send everything to my Icelandic bank, rather than my Danish bank. New bank information can be found here. I do this for simplification and other reasons that I am going to go into later (when feeling less down from all this being broke).
