Minor earthquake swarm on Reykjanes peninsula

Yesterday (30-October-2014) there was a minor earthquake swarm on the Reykjanes peninsula in Krýsuvík volcano. Around 30 earthquakes where recorded in this swarm.

Largest earthquakes in this swarm had the magnitude of 3,1 and 3,3 other earthquakes where smaller. This was tectonic only earthquake activity from the looks of it. I don’t know if more earthquakes are going to happen.

      1. IMO says for the time being 5,0, but it is not really checked (just 50%) and still no real depth (the afore mentioned 1.1 km).

  1. Thank you, Jón, for the update on the Krýsuvík swarm. 🙂

    You say, that you think the quakes are tectonic. But why are all more or less on the same place and not distributed over a wider area? Or along a fault? It could be part of Krýsuvík swarm, but also of Brennisteinsfjöll fissure swarm. http://www.geothermal-energy.org/pdf/IGAstandard/SGW/2013/Hersir.pdf

    BTW: What is the background noise at the KRI plot, noise from the high temperature /geothermal area at Seltún? http://hraun.vedur.is/ja/drumplot/allarsort.php
