A minor earthquake was detected in Hekla volcano on 21-June-2013. This earthquake was at north-east side of Hekla volcano, it had only the magnitude 0.6 and depth of 8.3 km. This is not at good detection according to Icelandic Meteorological Office person that I did speak to about this earthquake today.

This earthquake is just one earthquake in series of earthquakes in Hekla volcano. While this earthquake was poorly located due to almost not being detected, I am sure that the only reason this earthquake was recorded is due to more SIL stations around Hekla volcano that have been set-up in the past two years.
There are no signs of eruption is about to start in Hekla volcano.
