Small earthquake swarm detected at Iceland’s Katla volcano

August 28, 2011 – ICELAND -  A small earthquake swarm has been detected under the Mýrdalsjökull glacier where Katla sits. The caldera is 10 km (6 mi) in diameter and is covered with more than 200–700 metres (660-2,300 ft) of ice. The strongest quake in the latest burst of new tremors measured a 2.2 on the magnitude scale. A volcano this size produces a large amount of seismic tremors before there is an eruption so it is something only to monitor at this point. Katla is capable of producing a VEI6 eruption, which would be about 100 times more powerful than the 2010 eruption of its little sister Eyjafjallajökull. Katla last erupted in 1918 and many geologists say the two volcanoes unusually erupt in concert. –The Extinction Protocol
