A new earthquake swarm has started in Hengill volcano. This earthquake swarm is in the same location as a earthquake swarm that took place there few weeks ago (see here).
So far this earthquake swarm has mostly been made out of small earthquakes. But all earthquakes are below ML2.0 in size so far.
It is unclear why this earthquake swarm is taking place. But the reason might be that the geothermal power plant that is in the area is pumping down or up ground water.
