Using the seismic activity model in the National Seismic Hazard Maps for Japan, risk curves were calculated for the exceedance probability in 30 years regarding building damage, i.e., the number of completely destroyed buildings, due to earthquake motion in municipalities throughout all of Japan. In calculation, building data were created using 250 m mesh, and loss functions of wooden and nonwooden buildings were set. Analysis was performed by constructing a methodology considering the spatial correlation of dispersion of earthquake hazards and dispersion based on the planer extension of municipalities. Furthermore, we show the usage of calculated risk curves, for selecting assumed earthquakes and quantitatively estimating aseismic effects of wooden buildings.
