In this study, we propose a method to efficiently calculate ground motions for inland crustal earthquakes using a database of waveforms at seismic bedrock calculated by assuming various source and path characteristics using the statistical Green’s function and by considering empirical site amplifications at each location. We confirmed that the surface ground motions calculated by the proposed method can reproduce the observation records as accurately as the recent GMM in terms of the response spectra. The residuals between the proposed method and earthquake records were calculated. The proposed method was able to evaluate the residuals with less variation than recent GMM by taking into account empirical site amplifications of the sites.
