Validation of Deep Velocity Structure Model in the Kyoto and Nara Basins Using Autocorrelation Functions of Strong Motion Records

Abstract

Two-way travel time information obtained from autocorrelation function analyses of strong motion waveform data can be used to test and improve velocity structure models of sedimentary basins. The waveform data from strong motion stations in the Kyoto and Nara basins were analyzed in this study. The two-way travel time of SH-wave was estimated from the stacked autocorrelation function for each station, and it was compared with the theoretical two-way travel time of deep velocity structure model for the studied areas to check the performance of the present velocity structure model.
