Ongoing earthquake swarm in Reykjanes volcano

There is a an ongoing earthquake swarm in Reykjanes volcano and it has been going on for more than a week now. Location of this swarm has moved a little and the main earthquake activity is now at Reykjanestá area out in the ocean. There have been five earthquakes with magnitude above Mw3,0 today (13-May-2022) and the largest so far had a magnitude of Mw3,5.

This earthquake activity suggests two things. Either the magma has not been able to find a path to the surface close to Grindavík town. The second option is that there are two dyke intrusions happening in Reykjanes volcano. This earthquake activity slows down but never fully stops it seems. It is unclear why that happens. I am expecting earthquake activity to get stronger until an eruption starts somewhere in Reykjanes volcano.
