After the eruption of Eyjafjallajökull in 2010, many economic losses ensued. Did insurance agencies and risk monitors account for this natural event? I am sure they did; or, at least they expected a small probability for an event of this scale. But what if a volcanic eruption thirty times larger and more violent occurs? This is exactly what will happen at Katla. As NOVA’s Doomsday Volcanoes explains, it is not if… but when will it erupt. Is the world ready? Katla has erupted twenty times since 930 AD; currently, Katla has not erupted for 95 years, the longest sterile period since 930 AD.
