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. However, as these waves traveled across the Indian Ocean at speeds exceeding 800 kilometers per hour, they carried an enormous amount of kinetic energy.
How the 2004 Tsunami Unfolded: From Seismic Trigger to Massive Waves
The Seismic Trigger: The Sumatra-Andaman Earthquake The genesis of the 2004 tsunami was a megathrust earthquake with a magnitude estimated between 9. The 2004 tsunami, often referred to as the Indian Ocean tsunami, was triggered by a massive undersea earthquake off the coast of Sumatra, Indonesia.
The immense pressure built up over centuries was suddenly released in a matter of minutes. The rupture occurred along the Sunda Megathrust, a massive fault line where the Indian Plate is forced beneath the Burma Plate.
How the 2004 Tsunami Unfolded: From Seismic Trigger to Devastating Waves
The Generation of Waves When the seafloor displaces vertically, it acts like a giant piston, pushing the water column directly above it. To conserve energy, the wave height began to increase dramatically.
