For large kH, which will occur for short wavelength waves, the function can be approximated by a line with slope = 0. In this case, where , the phase speed is approximately. The dispersion relationship is , which has first derivative, These waves are called deep water waves.

WebSpeed of a Tsunami • Remember, speed of shallow water wave is Celerity = 3.1 d, where d = ocean depth (in meters) So, average Pacific depth = 4500m, average speed = 3.1 * 4500 210 m/s = 750 km/h! All tsunami waves cross a given part of the ocean at the same speed (speed only depends upon water depth).
