Earthquake Swarm Keeps Iceland’s Katla Rocking

We’ve been keeping an eye on Iceland’s Katla for quite a while now and over the past year; the volcano has been showing signs that magma is moving under the ice-capped edifice. There have been frequent seismic swarms around and within the caldera that is currently filled with the Mýrdalsjökull (glacier) and on at least two occasions, small glacial outburst floods (jokulhlaups) have issued from Katla.
