- EVALUATION OF SITE SPECTRUM USING AMPLIFICATION FACTORS FOR EARTHQUAKE GROUND MOTION INDI CES AND H/V SPECTRUM OF MICROTREMOR
抄録
In this study, we proposed a method to evaluate a site spectrum using amplification factors for peak ground acceleration and JMA seismic intensity, H/V spectrum of microtremor at local government observation sites where seismic waveform records were not stored. Firstly, the amplification factors and site spectra of acceleration response spectra at JMA, K-NET, KiK-net observation sites in the Chubu region were evaluated by a regression analysis. The amplification factors and site spectra have a good correlation at less than one second of period. In order to improve the evaluation to site spectra at more than one second of period, we used a function approximated by the H/V spectra as a parameter of the site spectra. The site spectra by a regression analysis using amplification factors and the approximated function were evaluated. The precision of evaluation at more than one second of period was improved.
