Mechanisms of generation of free gravity waves in the ocean by surface seismic waves

The subject of this work is numerical simulation of the process of generation of gravity waves in the ocean of variable depth by surface seismic waves. Physical mechanisms of generation of gravity waves are discussed. Theoretical estimates of their amplitudes are compared with the results of numerical experiments. It is shown that the horizontal component of the seismic wave generates gravity waves much more effectively than the vertical one. Also it is shown, that the key parameter determining the amplitude of gravity waves is the steepness of the underwater slope.
