Earthquake swarm on the Reykjanes Ridge

Yesterday (12.02.2017) and today (13.02.2017) there has been a earthquake swarm on the Reykjanes ridge. For this area of the Reykjanes ridge, this earthquake swarm is normal. It doesn’t appear that it was due to magma movement and only tectonic in nature. The area in question is a fault valley according to ship survives (I think).

Largest earthquakes in this swarm had the magnitude of 3,1 and 3,2. Depth in this earthquakes swarm was from 17 km and up to 2,4 km (there is some error margin). It appears that this earthquake swarm is over for now. It might restart again with double or triple amount of earthquakes happening, there is also a equal good chance of that not happening. All that can be done is to wait and see.

  1. There has been some earthquake activity north of Kolbeinsey Island. A swarm happened yesterday (15.02.2017), it was strong. Currently I’m waiting for manual location for it. Earthquake activity has been slightly increasing on the Reykjanes ridge for the past few days, but not enough for me to write about it at the moment.

    There was also an interesting earthquake in Hekla volcano system, just one (not enough to write about).
