The 2004 tsunami, often referred to as the Indian Ocean tsunami, was triggered by a massive undersea earthquake off the coast of Sumatra, Indonesia. However, as these waves traveled across the Indian Ocean at speeds exceeding 800 kilometers per hour, they carried an enormous amount of kinetic energy.
2004 Tsunami Wave Height Explained: Understanding the Science and Impact
Plate Tectonics and Energy Release The Earth's lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere below. The rupture occurred along the Sunda Megathrust, a massive fault line where the Indian Plate is forced beneath the Burma Plate.
The Generation of Waves When the seafloor displaces vertically, it acts like a giant piston, pushing the water column directly above it. This made it the third most powerful earthquake ever recorded on a seismograph.

The sheer scale of the event left entire communities obliterated and claimed over 230,000 lives across 14 countries. The phenomenon known as "runup" occurred, where the water rushed inland, often traveling kilometers away from the coastline.
