When the seabed is vibrating due to earthquake, not only the compression waves in seawater but also the free-surface waves occur at the same time and these interact with each other. This paper is numerically studied the interaction between wave elevation on free surface and compression wave caused by earthquake. The kernel function satisfying the wave equation in compression wave field is introduced and the seaquake forces, which satisfy the free-surface boundary condition in three-dimensional time domain, are calculated by making use of the boundary integral equation method. The calculated seaquake forces, which are not considered with free surface wave elevation and considered with free surface wave elevation, will be compared respectively.
