This is a short update because there’s a lot going on.
- Largest earthquake during the last 24 hours close to Eldey island had a magnitude of Mw4,5.
- This earthquake swarm looks like a dyke intrusion. Since the area is out in the ocean it is impossible to be sure.
- Difficult to know if an eruption is going to happen in this area. If an eruption happens, effects are unlikely to be big because of ocean depth.
It is my opinion that is unlikely to be an earthquake activity that is connected to the inflation in Fagradalsfjall mountain. Those earthquakes are closer to Fagradalsfjall mountain. It can’t be ruled out, but is unlikely to be the reason for this activity. Earlier activity in this same area also makes this unlikely to be a tectonic earthquake activity. It can’t be ruled out. Areas out in the ocean are always more difficult to figure out than activity on land with easier access.
