Earthquake swarm in Hengill volcano
Yesterday (23-March-2014) and Today (24-March-2014) an earthquake swarm took place in Hengill volcano. This earthquake swarm has its source in water being pumped down into the ground from Orkuveita Reykjavíkur (geothermal plant in this area).

This are not volcano related. This happens when cold water (polluted) is being pumped back into the ground. That makes earthquake swarms like this one common.
