I did check up on the activity in Hamarinn volcano today. It turns out the earthquakes in that area are mostly glacier quakes, that means they are formed by the ice and are not real earthquakes as such. It is difficult to locate glacier quakes, it is also unclear why this glacier quake activity is taking place. There is a chance of glacier flood taking place soon, but so far nothing has been detected.
I am expecting more glacier quakes to take place in the next few days to weeks in this area.
