That is all I know about this earthquake, that earthquake was also slightly more north then current swarm. Why this earthquake activity is happening is unclear since there are not any known volcanoes in this area or earthquake faults. There is a low (as in degrees of hot water) hydrothermal area in this area and recent news articles have suggested that this earthquake activity might be connected to that area. That is at best speculation and nothing has been proved so far. The existence of this low hydrothermal area shows that magma is in the crust in this area at shallow depth and has been for a while. For hydrothermal area to form, both cracks in the crust needs to be open and magma needs to reach 1 to 2 km up in the crust to warm up ground water in the crust.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today (1-February-2022) at 00:05 UTC an earthquake with magnitude of Mw3,7 took place close to H\u00fasafell.
