I notice that there is a small, yet growing earthquake swarm taking place close to a small mountain named Upptyppingar. This mountain is within the fissure swarm of Kverkfjöll volcano but the area is in it self not active volcanically.
Few years ago (2007) there was a earthquake swarm in this area that did have something about 2000 earthquakes over a 48 hour period. The reason why there is earthquake activity in this area is due to magma being pushed up into the bedrock below. This process is something of the same that took place before the Eyjafjallajökull volcano eruption. But with the major difference that here is no central volcano doing this.
Earthquake pictures from IMO from that time. No map sadly as I forgot to save them or they are stuck on my main computer that holds all my geological data.
