MODELING OF PHASE CHARACTERISTICS FOR SYNTHESIZING STRONG EARTHQUAKE MOTIONS

抄録（英）：
Modeling the phase characteristics of seismic wave motion is important for the synthesis of realistic seismic ground motion. We have developed a simple simulation model which takes into account phase changes produced by the rupture of an earthquake fault, the transmitting path effects and the local soil amplification effects. We classified the origins of phase shifts into the following groups; 1) the time delay caused by rupture propagation on the fault plane, 2) the effect of the path of transmission, and 3) local reflection and refraction of seismic wave. Cepstrum analysis was used to deconvolute the observed seismic waves into a train of impulses, a system transfer function, and a function that expresses local geological effects.
