seismic waves attain the tremendous velocities.

In the open ocean, its not a wave like we might normally think of it. Its more like a shock wave. It passes under boats without being noticed.
As it approaches shallower water it encounters the bottom and this slows it down. It also will start pushing a swell upward, which also slows it down.

Waves caused by seismic events travel at the same speed in water as all other waves but are bigger. There may be a shock wave which is more akin to a pressure or sound wave. These will travel at up to the speed of sound in water (about 1500 m/second) but do not do much damage or are easily observable at any distance.

suden and tremendus ground movement wich coases large amounts of water displacement
