The Generation of Waves When the seafloor displaces vertically, it acts like a giant piston, pushing the water column directly above it. In some locations, the waves slowed to the point where the massive amount of water behind them continued to surge forward, causing the wave to rise vertically.
How the 2004 Tsunami Formed: From Seafloor Shift to Massive Waves
Plate Tectonics and Energy Release The Earth's lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere below. Unlike typical strike-slip earthquakes that slide horizontally, this event involved a violent vertical displacement of the seafloor, pushing a massive column of water upward.
To conserve energy, the wave height began to increase dramatically. The immense pressure built up over centuries was suddenly released in a matter of minutes.
How the 2004 Tsunami Formed: Seafloor Displacement and Wave Generation
On December 26, 2004, the world witnessed one of the most devastating natural disasters in recorded history. The Seismic Trigger: The Sumatra-Andaman Earthquake The genesis of the 2004 tsunami was a megathrust earthquake with a magnitude estimated between 9.
