Katla, one of Iceland‘s most powerful volcanoes joined Reykjanes peninsula yesterday with its own intense earthquake swarm. The largest quake in this swarm was a powerful 4.5 magnitude quake at 22:18, immediately preceded by a second 3.2 magnitude quake.

Katla, which is hidden beneath Mýrdalsjökull glacier in South Iceland is believed to be long overdue for an eruption. The volcano has shown increasing signs of activity in the past few years, following the 2010 eruption in Eyjafjallajökull.

A professor of geophysics at the University of Iceland told the local news site Vísir that the quake in Katla was unusually large, the largest quake in Katla since 1977.
