ESTIMATION OF NEAR-SOURCE GROUND MOTIONS OF THE 1980 IZU-HANTO-TOHO-OKI EARTHQUAKE BY DWFE METHOD

抄録（英）：
In this study, the discrete wavenumber/finite element (DWFE) method (Olson, 1982) and the fault dislocation theory were applied to the case of the Izu-Hanto-Toho-Oki earthquake (M=6.7) of 1980. Ground motions were computed at the site of Kawana near the source region. The displacement seismograms synthesized from the theoretical method were compared with the actual strong-motion records. We were able to reproduce the recorded waveforms, particularly of body waves and the first portion of surface waves, by the theoretical synthesis method with a realistic crustal structure. The best agreement between the observed and synthesized waveforms was obtained for relatively long-period components with periods of 0.5-6 sec. The acceleration response spectra calculated gave a good estimate of those observed over the period range from 0.5 to about 10 sec .
