The speed at which energy released in an earthquake moves through rock. As has been pointed out there are different types of waves released in an earthquake and they move at different speeds. The speed of energy through rock also depends on the density of the rock. Dense rock (heavy for its volume) will conduct energy faster than less dense rock (light for its volume). Scientists use these facts to look inside the earth at its structure and to determine the location of the earthquake by timing how long it takes the waves to arrive at a certain location.

Seismic waves are the energy waves produced by an earthquake, so seismic velocity is the speed at which the waves travel:
P waves (compressional) travel 4 to 7 km per second
S waves ((transverse) are much slower at 2 to 5 km per second.

200mph+i believe it is the velocity reached by a natural occurring wave of material disrupted and is moving from a earth reaction to variables in conflict with the bath tub of water (oceans) that is objectively offset by land masses
