Over the past few days (since 26th of October 2010) there have been earthquakes happening at Blöndulón. This earthquakes are intraplate earthquakes and it unclear why these earthquakes are happening.
At 02:35 UTC a earthquake with the size of ML4.0 did hit Blöndulón according to automatic SIL system that Icelandic Met Office has. So far this is the strongest earthquake to hit this area since the earthquake swarm did start. This earthquake appears to be a start of new earthquake sequence in this area. But several smaller earthquakes have happened as a result of the ML4.0 earthquake. The depth of the main earthquake was 1km. I do expect that it was felt in nearby farms that are closest to Blöndulón.
I am expecting more earthquakes in this area over the next few days. It remains to be seen if they grow in size or not.
When reviewed the size of this earthquake was ML3.8 at the depth of 21.1 km.
