C O N C L U S I O N S Analytical CPSR curves for reverse faults in Japan were calculated considering various fault angles and seismogenic thicknesses. Results indicate that, at the same magnitude, the most influential parameter affecting the variation of the analytical curve is the seismogenic thickness. In computing the analytical curve, we considered a seismogenic thickness of 10 km in accordance with the seismogenic depth derived from the analysis conducted in this study. We then compared it with the empirical regression derived from Takao et al. (2013), which was conducted exclusively using historical earthquake catalogues of Japan. The match between the analytical curves and the empirical regression suggests that CPSR should be conducted using area- specific parameters rather than global averages.
