The numerical model is described for the simulation of dispersive gravity waves and hydroacoustic waves generated by seismic ocean-bottom motions. The model consists of two dynamically coupled modules. Deep-water module employs 3D equations of linear potential theory of compressible liquid. Shallow-water module employs 2D equations of linear long-wave theory. The numerical model is used for simulation of the 2007 Central Kuril Island tsunami. Manifestations of water compressibility in the vicinity of the tsunami source and phase dispersion of tsunami waves are discussed.
