When the Indian Ocean tsunami struck on Dec. 26, 2004, no one saw the massive waves coming. Authorities in Indonesia, where a 9.1 magnitude quake sparked the tsunami, weren't able to send out an alert because the country's sensor system had been hit by lightning. Thai officials did send a warning, but only after the first deadly wave hit. And in India, word of the disaster went to the wrong official.
