Seismology & Earthquakes

Seismological Settings

Deep ocean trenches range from 3,000 to 6,000 meters. Continental shelf is usually < 200 meters.
Earth Telemetry
Tsunami Wave Propagation Velocity
713 km/h
(198.1 meters/second)
Shallow water wave physics:

In deep oceans, tsunamis travel at jet-liner speeds but with tiny amplitudes. As they approach shallow shorelines, they slow down and build massive wave heights (shoaling effect).
