Today (3-June-2014) a magnitude 2,5 earthquake took place south of Hekla volcano. Depth of this earthquake was 9,6 km. It did appear clearly on my geophone in Heklubyggð, it can be viewed on-line here.
There was no signs of harmonic tremor or anything suggesting that volcano eruption was about to start following this earthquake. Everything is quiet for now. Some minor aftershock activity took place following the main earthquake. I am expecting minor earthquake activity to continue to take place at this location. Earthquake activity at this location has happened before in similar way as it did today. When eruption do starts in Hekla volcano, there is going to be a lot more earthquake activity then took place today. Until that happens, there is no reason to worry about this. If you are going to hike on Hekla volcano then please do go safe route, since Hekla volcano is well known for sudden eruptions with no warning at all, besides the earthquake swarm in the hour or two before a start of an eruption.
