Today (31-January-2020) an earthquake swarm started again north of Grindavík village in the volcano of Reykjanes (both). Largest earthquake so far had the magnitude of Mw2,5. Other earthquakes have been smaller in magnitude but that might change without warning. Inflation today is close to 45mm and continues to increase by each day. The source of this information can be found here.

The fault lines that are now active are three based on current earthquake pattern. This fault lines might just make an earthquakes and might not erupt. At the writing of this article there is no sign that magma has started to move towards the surface. Stronger earthquake swarms can happen without warning and they don’t have to be close to the area that is now inflating. Since the inflation is changing the stress levels in nearby crust that is going to break once the crust stress level has been reached. When that happens is not something that is possible to know.
