Interesting earthquake activity took place in Vatnajökull glacier today (03.06.2013). This earthquake activity took place just south of Grímsfjall volcano, that last erupted in the year 2011.

This earthquake activity is interesting, since it started after the eruption in Grímsfjall volcano at that area. It has been suggested that this activity is due to stress changes in this are, following the eruption in Grímsfjall volcano in the year 2011.

I am not sure what is going on in this area, no volcano is known, or volcano fissure is known in this area. But that might well just be because this area is covered with a thick glacier. What makes this also interesting is the fact this area has been having earthquake activity since the year 2011 and there doesn’t seems to be any end in sight. This is clearly something worth keeping a eye out for, even if nothing happens in this area for a long time.
