A heterogeneous faulting model with two strong asperities of high stress drop to fit the simulated spectrum to the observed one by Hartzell and Heaton (1985) for the 1946 Nankai earthquake is proposed in this study. The locations of two asperities are determined, referring the inversion result of geodetic and tsunami data by Satake (1993). We find that for long period motion, the simulated displacement at SMT fits well the observed, and that for short period motion, the simulated peak velocities show good agreement with the Seismic Intensity distribution in wide region including near source. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
