For the past few days there has been summer earthquake activity in Katla volcano. None of the earthquake have reached magnitude 2,0 so far.
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.
