As far as I'm aware, no psychic claims to have predicted the recent tsunami. It was, however, predicted by a 10-year-old girl.
Tilly Smith, on vacation with the rest of her family in Phuket, Thailand, noticed the tide leaving suddenly. Recalling a geography lesson about earthquakes and tsunamis taught the previous term, she realized the water would return as a wall of water in about ten minutes' time. Smith alerted her mother, leading to the evacuation of Maikhao beach and a neighboring hotel and the saving of hundreds of lives.
