Sound’s speed in seawater is of particular interest to anyone trying to use sonar or other underwater exploration techniques. The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. But ocean waves are much slower:
Wave velocity is the speed of the wave. Velocities of normal ocean waves are about 90 km/hr while tsunami have velocities up to 950 km/hr (about as fast as jet airplanes), and thus move much more rapidly across ocean basins.
