Earthquake swarm close to Hveravellir (Langjökull north)

I don’t know a lot about this earthquake swarm close to Hveravellir (Langjökull north), due the lack of information. What I do know is that an earthquake swarm is taking place there and the largest earthquakes so far have the magnitude around 2,1. Largest reviewed earthquake had the magnitude of 2,1 at 2,1 km depth. Other than this information I don’t know for sure what is going on in this area.

This earthquake swarm is appearing clearly on nearby SIL station and only this one SIL station. Copyright of this image belongs to Iceland Met Office.
The drumplot of that SIL station also shows this earthquake swarm clearly. Copyright of this image belongs to Iceland Met Office.

I’m currently guessing that around 50 – 100 earthquakes have taken place so far, but without accurate data its difficult to know. The magnitude in this earthquake swarm is from 0,0 – ~2,1 so far. Larger earthquakes can’t be ruled out, but as the magnitude grows, so improves the SIL network ability to locate the earthquake magnitude and depth properly. For the smaller earthquakes, they are only going to appear on one to two SIL stations and that is not enough data to properly locate them or figure out exact magnitude.

I’m going to post updates to this earthquake swarm as it happens if needed.

  2. Where is the “Ste” SIL station located? Close to Hveravellír? Can’t seem to find it in any of the maps.

      1. Thanks. I often use that map to locate SIL stations I can’t remember. But it could use an update!

    1. Indeed, nice achievement.
      Up to 12% of the Icelandic population is now in France.
      It must be calm in Reykjavic. (even the earthquackes are low)
