| | Abstract | | In this study, subsurface structures of strong ground motion observation sites in Tottori Prefecture were determined to obtain information for prediction of earthquake strong ground motion at each sites. S-wave velocity models and predominant period of H/V were obtained using array microtremor and observation 3-components single-site microtremor observations data at 43 sites. PS-P times with receiver functions were calculated using acceleration data at observation sites. The PS-P times of the receiver functions were compared with PS-P times that calculated from the subsurface structures. Further, we examined relationship of gravity basement and results of microtremor data analysis. |
