It started out as a morning like so many others in Southeast Asia - bright, beautiful and warm. But Dec. 26, 2004, would soon go down as the day one of the world's worst natural disasters struck.

At 7:59 a.m. local time, about 150 kilometres off the coast of the Indonesian island of Sumatra, two tectonic plates heaved under the sea along a 1,000 kilometre-long fault line. The result: a magnitude 9 earthquake - the most powerful the world had seen in 40 years.

Parts of the sea floor rose by about 10 metres, displacing hundreds of cubic kilometres of seawater. That generated a tsunami - a series of huge waves that quickly fanned out across the Indian Ocean.

The waves moved so quickly, there was no time to sound the alarm. Walls of water slammed into coastal areas of Indonesia, Malaysia, Myanmar, Thailand, Bangladesh, Sri Lanka, India and - thousands of kilometres away - Somalia in East Africa.

The waves destroyed whatever lay in their path: from the built-up tourist resorts of Thailand to isolated fishing villages in Indonesia and Sri Lanka. Thousands of people were killed. The number of dead rose by the hour as the extent of the devastation became apparent.

On Dec. 29, 2004, military teams finally reached the west coast of the island's northern province - Aceh - about 150 kilometres from the quake's epicentre. They found thousands of bodies. Three-quarters of the coast had been obliterated.

Tens of thousands of people were missing.

The disaster is believed to have killed more than 150,000 people in Asia and Africa, more than half of them on Sumatra.

Below is a set of QuickBird image files selected from the DigitalGlobe ImageLibrary. The imagery has been resampled from 11-bit to 8-bit, and compressed into JPEG format for on-screen viewing. These images should not be stretched beyond their current size. They have been rescaled in most cases to show an area of interest, and thus do not represent the full resolution of the original QuickBird image.
