Fault models of the 1938 Shioyazaki-oki earthquakes, event 1 (May 23) and event 2 and 3 (Nov. 5), are characterized using the slip distributions on the fault plane by waveform inversion analysis. Stress parameters of each asperity Δσa are estimated as 37MPa for event 1 and 22MPa for event 2 and 3 from empirical Green's function method (EGFM) by simulating the seismic intensity of JMA observation stations which locate in near fault region. Short-period spectral level of event 1 is higher than those of event 2 and 3 which are as high as that of the 1978 Miyagi-ken-oki earthquake. The spatial distribution of seismic intensity 5 for each event is well reproduced by EGFM using the proposed fault model in this study.
