It is unclear at the writing of this article what this means. Glacier flood from Mýrdalsjökull glacier following this earthquake activity is a possibility. Currently there are no signs that an eruption is about to start, that can change without warning. This might also just be normal summer activity in Katla volcano. At the writing of this article, the answer of what is going on is not clear.
