On 26 December 2004 an English girl, Tilly Smith, was walking on a beach with her family in Thailand .When down to the sea,Tilly saw that some thing was wrong. The water was all frothy, said Tilly. It was bubbling Tilly remembered a short film her class had seen at school about a massive wave called a tsunami. In the film the sea became frothy just before the tsunami struck. Tilly knew that a tsunami was coming she began to scream at everyone to get away from the beach. Minutes later, the Great Indian Ocean tsunami struck the coast.
