We examined the validity of the method for generating 3-component strong ground motions using the stochastic Green's function by applying it to the 1995 Hyogo-ken Nanbu earthquake. The fault model including dynamic parameters is almost identical with that of Kamae and Irikura (1997) and is composed of three large slip areas. Comparing simulated seismic motions with the recorded motions at Kobe University, two horizontal components show a good agreement in waveform and amplitude, but a vertical component is in less agreement. To obtain a better agreement in the vertical component, we incorporated P wave radiation and added another slip area in an upper part of the fault model. However, observable improvement was not recognized, suggesting that comprehensive reexamination is required for the data, the fault model and the synthesis method.
