on 26 December 2004 an English girl, Tilly Smith,was walking on a beach with her family in Thailand. When they went 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 has seen at school about a massive wave called a tsunami. In the film the sea become frothy just before the tsunami struck.Tilly knew that 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.
