Annotation

A numerical method is used to study the possibility and efficiency of tsunami generation. by an underwater landslide. The effect of the rate and travel distance of the landslide on characteristics of the wave it generates is considered at slope angles within 0-0.06 rad corresponding to actual slopes of the sea floor. It is shown that the dependence of the energy and amplitudes of the waves on the rate of the landslide are of resonance nature, and that the position of the resonance region depends on the landslide travel distance both for a horizontal and a sloping sea floor.
