However, as these waves traveled across the Indian Ocean at speeds exceeding 800 kilometers per hour, they carried an enormous amount of kinetic energy. Understanding how this catastrophe unfolded requires a look at the geological forces that set the chain of events in motion long before the first wave crashed ashore.
Geological Evidence of the 2004 Tsunami's Aftermath and Impact
On December 26, 2004, the world witnessed one of the most devastating natural disasters in recorded history. Because the energy was spread over such a vast distance, the waves in the open ocean were not particularly tall, often measuring less than a meter in height and going unnoticed by ships at sea.
The rupture occurred along the Sunda Megathrust, a massive fault line where the Indian Plate is forced beneath the Burma Plate. Shoaling and Runup: The Deadly Transformation The true destructive power of the tsunami was unleashed when the waves approached the coastline.

The depth of the ocean played a crucial role; in deep water, the wave energy extends far below the surface, allowing the wave to maintain its speed and power over thousands of kilometers. In the region of the 2004 earthquake, the Indian Plate converges with the Burma Plate at a rate of about 6 centimeters per year.
