Tsunami

"When Krakatoa, an island volcano off the coast of Java, erupted on August 27, 1883, it spewed debris 24 miles into the air, was heard 4000 miles away, and caused barometers throughout Europe to go berserk. Tsunamis destroyed 165 villages and killed 36,417 people, but... the eruption's devastating effects were not only environmental ... but also political. Winchester notes that prior to the eruption, a Javanese Muslim priest had predicted that floods, blood-colored rain, volcanic eruptions, and death would precede the beginning of a holy war against the infidel. The resulting rash of murderous attacks by fundamentalist Muslims against European colonists living in their midst, he argues, was also a reaction to the escalating threat of Western imperialism into Muslim territory".
