Tilly Smith, a 10-year-old British schoolgirl, saved approximately 100 people from the Indian Ocean tsunami while vacationing with her family at Mai Khao Beach in Phuket, Thailand. Two weeks prior, she had learned about tsunamis in her geography class, including the warning signs such as the ocean frothing and receding. Recognizing these signs on the beach, she urgently alerted her parents, who then informed hotel staff. The staff evacuated the beachgoers just minutes before the tsunami struck, making it one of the few areas on the island with no reported fatalities.
