The 2010 eruption of the Eyjafjallajokull volcano in Iceland provoked economic chaos by paralyzing a major air traffic network for days. This eruption, however, was mild.

Europe has come to realize that a colossal power sleeps beneath Iceland, while Icelanders for centuries have learned to live amongst their volcanoes.
