The Indian Ocean tsunami
At 7.59 in the morning of 26 December 2004 an earthquake of magnitude 9.1 struck under the sea off the Indonesian island of Sumatra, one of the largest ever recorded. It lifted the sea floor and sent tsunami waves racing across the Indian Ocean, up to 30 metres high on the coast of Aceh.
The waves reached Sri Lanka, India, Thailand, the Maldives and as far as East Africa. About 228,000 people died or were never found, more than in any tsunami on record. The disaster led to a warning system for the Indian Ocean, set up with UNESCO’s help in the years that followed.
