NASA to release animated satellite footage of Japan tsunami

December 6, 2011 12:00:00 AM PST
NASA will release an animation of the devastating tsunami that struck Japan in March.

Satellite data was used to create the animation that shows the tsunami was the result of at least two waves that combined to create a more powerful tsunami.

Ocean ridges and mountain ranges below the surface of the water channeled the waves created by the magnitude 9.0 quake, bringing them together far-out at sea to form a merging tsunami.

The earthquake and tsunami killed nearly 16,000 people.
