A swarm of thousands of earthquakes have been recorded on Iceland’s Reykjanes Peninsula over the past three weeks. It’s a strong indication that a volcanic eruption is imminent. The town of Grindavík has been evacuated as a result. The Icelandic Meteorological Office has a page with updates and maps of earthquakes and ground deformation from the magmatic intrusion (examples above). A post on Earthquake Insights has more maps, plus geological and historical context.
