Abstract

The problem of the tsunami wave generation by the submarine landslide, which is moving along the bottom slope, is studied. A number of numerical experiments were carried out for a model submarine landslide. A maximum amplitude and the wavelength were defined for various landslide profiles and their moving rates. As expected, the highest waves are generated when the velocity of the submarine mudslide is equal to the long wave propagation velocity. The landslides, which are moving slower and faster than the resonant one, generate waves with a lower amplitude and a bigger wavelength. The generated waves have a fairly expressed directivity of radiation.
