First, two one-dimensional layered ground models are prepared: Model 1, a four-layered model based on a boring log and Model 2, a two-layered model based on airborne laser profiler and geological cross sections. Seismic records with peak ground acceleration 8 to 141 cm/s2 are used for analysis, which were observed by six seismic stations in the study area. Incident waves at bedrock level of each observation point are calculated by one-dimensional equivalent linear analysis. Two ground models are compared with respect to acceleration response spectra. Then, acceleration response spectra at bedrock level at each observation point are compared in regard to each earthquake event. The results suggest that it is necessary to increase the spatial density of bedrock data to make an accurate ground model and to consider influence of surface waves and oblique incidence in regard to the studied area.
