Today (04-September-2013) a minor earthquake took place in Hekla volcano. The magnitude of this earthquake was just 0.4 and the depth was 0.1 km, so this earthquake was not connected to magma movements of any type.

Based on how shallow this earthquake was, it is unlikely that it means anything in terms of possible eruption in the volcano. At the moment there are same chances for Hekla volcano eruption as any other day of the week, that has not changed at all.
