A set of source rupture models for the 1997 Yamaguchi, Japan, earthquake are constructed using an inversion analysis of strong‐motion data. Synthetic Green functions and empirical Green functions (EGF) are adopted for a low‐frequency band and a high‐frequency band, respectively. Slip zones in the high‐frequency models correspond to the edge of the large slip zones of low‐frequency models in space and to the rupture onset in time. The calculated slip‐stress relations show that the stress decrease rate is more rapid in the high‐frequency models and that there is little slip at a constant stress level in all the models.
