Abstract: According to Cabinet Office's Research, when Nankai Trough Earthquake hit, leaving a wide range of area in Japan in devastating condition. To predict earthquake motions on the specific surface site, it requires source, path and site effects at least. In addition, taking loss effect by building foundation and structural vibration property into account, in such a way building response can be presumed. We used methods utilizing observed record of seismic motions and microtremor, such as the Empirical Green’s Function Method, a microtremor array, transfer function synthesis and modal analysis to predict the response of Aichi Prefectural Office Local Autonomy(APOLA) in Nankai trough earthquake. In particular, we observed seismic motions and microtremor in assessing site effects, transfer function synthesis and modal analysis uniquely. As a result of our predictions of ground motion at APOLA, there are two features. First, motion lasts as much as 110s. Lastly, the greatest motion arrives 90s after the earthquake occurs. Finally, we compared the results of prediction of ground motion at the APOLA to seismic scale quoted from cabinet office's research and acceleration response spectrum quoted from SPECIFICATION FOR HIGHWAY BRIDGEES PART V SEISMIC DESIGN.
