When the seabed is vibrating due to earthquake, the compression waves propagate into seawater on account of compressibility of water. The hydrodynamic pressure caused by seaquake is analyzed numerically in three-dimensional time domain and the calculated results will be compared with the experimental results in seaquake generation tank in Hiroshima University. We use the kernel function that satisfies the wave equation in compression wave field. In order to obtain the solution of the seismic wave fields, we calculate the hydrodynamic pressure in water by using of the Boundary Integral Equation Method (BIEM) in three dimensional time domain. The calculated hydrodynamic pressure, in case there are with walls and without wall, will be compared with experimental results.
