The earthquake swarm that started yesterday (03-May-2014) in Herðubreiðartöl continues. Information about this earthquake swarm changes quickly so this article about it is going to get obsoleted quickly. The largest earthquake in past 24 hours had the magnitude 3,9. Since around midnight over 370 earthquakes have been recorded. This means the earthquake swarm is more powerful in terms of earthquakes today than it was at the same time yesterday.

I am expecting more earthquake activity in Herðubreiðartögl next hours and even days. Since currently there are no signs of this earthquake swarm slowing down. The largest earthquakes (above magnitude 3,0) appear clearly on my geophone network website.
