Katla twitches

While the earthquakes in the region around Myrdalsjokull have remained concentrated in and around the Katla caldera for some time, they have been relatively small. However I see that one has just crept up above a value of 3. (Barely it is a 3.1). While in itself this is not significant, it continues to suggest that there is activity within the volcano that will, in time, create problems. There has been too little associated activity to suggest that this is, however, anything critical at this stage.

There is no more.
