The wave will start sounding when the depth equals half of the wavelength. For tsunamis, that wavelength is pretty long, and the wave might only be a meter or two at most in the deeper ocean. In the shallows, it is a question of how high the water can pile up. No one really knows what, if any, maximum height there is, but heights in excess of 100 ft. have been recorded.
Ok. Thx.
A hundred foot high wave is bad, but as important is how far inland the water would go. Any calculations for that?
