Strong earthquake swarm 100 km north of Kolbeinsey island

During the night of 28-February-2019, starting on 27-February-2019 an strong earthquake swarm took place 100 km north of Kolbeinsey island. I don’t know if this was just a earthquake swarm or an eruption. The area is far from the coast and remote because of that. Depth of the ocean at this location is around 1 to 3 km and that makes any eruption invisible on the surface of the ocean.

Largest earthquake in this swarm had a magnitude of 4,3 (at 07:43 UTC) and second largest earthquake had a magnitude of 4,1 (at 07:37 UTC). Total number of earthquakes with magnitude above 3,0 was 16 at last review from Icelandic Met Office. I don’t know the total number of earthquakes recorded in this earthquake swarm. A lot of earthquakes where not detected because of distance from the SIL network. It looks like this earthquake swarm is over. Since there hasn’t been any earthquake activity detected for the last few hours.

    Is Kolbeinsey still above sea level? I wonder when it was last checked/measured.

  2. I have done minor updates to this article. This the article about eruptions in Iceland over the last 1000 years.
