Abstract;The purpose of this study is to grasp a "sea shock" phenomenon considering seabed condition. Therefore we introduce Green function which is used for the calculation for the response of ground displacement caused by dynamic pressure and calculation methods of response of seabed displacement caused by hydrodynamic pressure due to sea shock. Furthermore, we introduce a incident wave potential of sea shock phenomenon considering reflection and refraction on seabed boundary. The conclusions obtained by the present paper are that the calculation results of green function for elastic ground due to dynamic pressure is controlled rayleigh wave component. In addition, characteristics of seabed oscillation due to earthquake wave is changed substantially by the seabed. (author abst.)
