This earthquake activity appears to be normal in Katla volcano for the moment. The reason for this activity is melting of the glacier, that means less weight on the volcano, less pressure means changes to the hydrothermal activity inside the caldera of Katla volcano. It can be expected that this earthquake activity is going to continue for a while, at least until October at the longest, or to the time when it starts to snow again in Iceland.

  1. Some Earthquakes are rather deep – they are probably not related to the glacier? It seems that it is a combination of usual Summer activity and general increase of activity in iceland.

  2. Some strange quakes today, the first in the East Fjords region and a small swarm north and in between of Langjokull and Hofsjokull. Is there anything there in those regions ?

  3. LAst activity i think isn’t melting summer ice… the deep is the key .
