Yesterday (25. August 2024) at 23:56 UTC an earthquake with magnitude of Mw3,6 took place in Krýsuvík volcano. This earthquake was felt in Reykjavík area and other nearby towns.
This is a normal tectonic earthquake. I don’t know if it is a response to stress changes because of Svartsengi volcano cycle of inflation and deflation. This earthquake swarm seems to be over for now.
