The numerical modeling of mid-ocean tsunami propagation was carried out using the finite difference method of the linear shallow-water wave theory with a Coriolis force in a spherical co-ordinate system (Nagano et al., 1991).

As a reduction of Eq. (1.1), the shallow water wave equation can be used to describe the propagation of ocean waves in shallow water and has been investigated in many literatures [24 26].
On the basis of Fourier synthesis of frequency components, a WKBZ mode approach to pulse propagation in ocean channels is presented, and applied to calculations of propagation of a signal energy and waveform.
In a strict sense, it is known that the density structure of the real ocean contributes to the slow propagation of ocean gravity waves.
This case is demonstrated for the sound propagation in the ocean.
They correspond to acoustic propagation in the ocean in the presence of a current, and to acoustic propagation in shear layers over flat plates.
In this environment and for Ultra-Low Frequency waves ( to Hz, denoted further ULF) classical beamforming techniques are inappropriate because they do not consider multipath propagation phenomena and ocean acoustic channel complexity.
When running COMCOT to simulate the tsunami wave propagation in deep oceans, the shallow water equations are solved in a spherical coordinate system and the effects of Coriolis force are added to Eqs. (2) and (3).
It is fairly straightforward to model tsunami propagation in the open ocean, as reviewed by Satake (2002).
