A method for seismic hazard evaluation which deals with response spectrum information is presented. A local city near Tokyo facing the Pacific Ocean is selected for the case study. It serves as a model of earthquake sources which, in turn, are based on summarized historical earthquake and geological data. Using the model, PGA-dependent spectral shapes as well as seismic hazard curves of PGA are consistently evaluated on the surface of the bed rock, with the hazard curves regarding absolute acceleration response spectra being obtained. Through application of this method, the effects of surface layer profile can be properly treated.
