A tsunami is a shallow-water wave even in the deep ocean, travelling at √(g·h). Over 4 km of water that is roughly 700 km/h — jet speed — yet only tens of centimeters high. As it reaches shallow coast it slows and its amplitude grows as h^(−1/4) (Green's law), piling into a destructive wall.

Current speed0 km/h

Deep amplitude0.5 m

Coastal amplitude0.0 m

Governing equation

v = g h = 9.81 \cdot 4000 = 198 \frac{m}{s}

Reading this result: At 4000 m depth the pulse moves at ~713 km/h; Green law shoaling then amplifies its 0.5 m deep-water height as it nears the coast.
