Abstract
The spectral attenuation character in high frequency range during the 1995 Hyogo-Ken Nanbu Earthquake is examined in order to propose a high-cut filter for strong ground motion prediction in this paper. It's cleared that the simulated spectra by the stochastic Green's function method are overestimated in high frequency range. The most suitable high-cut filter for two source models and four target sites is examined by comparing simulated spectra with observed ones. The obtained most suitable filter is very effective for strong ground motion prediction using the empirical Green's function method or stochastic Green's function method.
