First we used a conventional Greenユs function method to sum up statistical Greenユs functions for a moderate size earthquake and synthesize them to predict strong motions due to the next Nankai earthquake. We input these strong motions to dynamic nonlinear structural models in order to predict structural damage. Our nonlinear structural models are unique because they are multiple models with different strengths with different existence ratios. From the theoretical calculations we can determine damage ratios for different types of building. Based on this quantitative damage estimation and the building statistics we then calculate environmental load. Finally we evaluate the effect of the seismic management strategy on this environmental load due to the next Nankai earthquake.
