Tsunamis are mistakenly called tidal waves because, when approaching land, they look as a tide which suddenly rushes away and crashes back in a form of a … WebTsunamis are water waves in which the restoring force is gravity and the wavelength is greater than the ocean depth. Unlike shorter wavelength disturbances, the fluid motion extends throughout the water column. For a wave of surface amplitude h, the pressure difference that drives the fluid horizontally away from beneath a crest is about ρgh, where … greenville county jury duty

Webwhile everyday wind-generated waves have wavelengths that vary from around 100 to 200 m. 20. Runup is the maximum vertical height above normal high tide reached by a tsunami as travels over the land surface. 21. Drawdown 22. The periods of tsunami range from minutes up to 2 hours 23. The speed of a tsunami slows as it enters shallow water. 24. WebThe deeper the water, the greater the speed of tsunami waves will be. For example, at the deepest ocean depths the tsunami wave speed will be as much as 800 km/h, about the same as that of a jet aircraft. Since the average depth of the Pacific ocean is 4000 m (14,000 feet) , tsunami wave speed will average about 200 m/s or over 700 km/h (500 mph). fnf prolly
