Abstract

Local variations in static slip, slip velocity, or rupture velocity contributes significantly to the information research on ground motions. Therefore, the characteristics of asperity and the position of the single asperity, are quantified to recognize its influence to the high-frequency radiation. In this paper a modified empirical Green´s functions (EGF) method is suggested and used for ground motion simulation. The source parameters of asperity and rupture process are decided by the inhomogeneous fault. The synthesis of Tangshan earthquake in far field is used to study.
