It's twenty years since the deadliest tsunami in history. On December 26th, 2004, a 9.1 magnitude undersea earthquake struck 240 kilometres off the coast of the Indonesian island of Sumatra. In the hours that followed, a tsunami triggered by the earthquake surged across the Indian ocean, at speeds of 800 kilometres per hour. It brought disaster to 14 countries, wiping out entire communities in South East Asia and South Asia and impacting coastal areas as far away as East Africa. In total, at least 225,000 people lost their lives. SBS News Asia Correspondent Aaron Fernandes travelled to one of the worst affected areas, Indonesia’s Banda Aceh, to meet with those who survived.
