Minutes after the end of Christmas Day, 2004, an earthquake of immense proportions rocked Southeast Asia. It originated 250 kilometres off the west coast of Northern Sumatra. The fourth largest quake since 1900, the Sumatra-Andaman Islands Earthquake rated 9.0 on the Richter scale, causing a devastating tsunami that destroyed coastal areas rimming the Indian Ocean, and was recorded across the Pacific Ocean as far away as North and South America.

Banda Aceh was the closest major city to the epicentre of the massive earthquake that triggered the deadly tsunami that washed over the coastal areas along the rim of the Indian Ocean on December 26th. Located on the island of Sumatra in Indonesia, Banda Aceh was one of the worst hit areas, with whole chunks of the coastline swept away, fields and low lying areas flooded and buildings churned into heaps of debris.
