For the construction of a new bridge, the Japanese specifications for highway bridges stipulate to select a location or a structure type unaffected by surface rupture.Therefore, it is crucial to predict the amount of displacement caused by the surface rupture in a scenario earthquake. In this study, I revised the relationship between the earthquake magnitude and the maximum surface-rupture displacement. Further, I investigated the relationship between the surface-rupture displacement and the distance from the predicted active faults. Conclusively, I have proposed regression equations for the earthquake magnitudes and surface-rupture displacements that have high-correlational relationship with the strike-slip fault and dip-slip fault, based on the domestic and international earthquake reports. In addition, I have developed a methodology to estimate the largest surface-rupture displacement at arbitrary points.
