At 02:06 and 02:07 UTC there where interesting earthquakes in Bárðarbunga volcano system. What makes them interesting is that fact they did happen at 0.6 km depth one of them. But this area did see some volcano related activity (speculated) earlier this summer, that did result in large glacier flood. But it has been suggested that a minor eruption took place there around 10. July 2011.
What makes this earthquakes so interesting is that they seem to have a low period component in them. But it was seen on the Kálfafell SIL station, and other SIL station that was decent distance from the source of the earthquake.
Currently there is nothing that suggests that a eruption is about to start in this area. But that can change without warning given the current status of Hamarinn volcano system.
