Abstract
The purpose of this study is to clarify the effect of different protective facility damage levels on tsunami inundation. The facility damage level due to the combination of earthquakes and tsunamis is unknown, so the numerical inundation evaluation methodology is verified using the Monte Carlo method, which is used to determine the seawall damage level. In this study, 942 cases with different seawall damage levels were performed. The results indicate that some areas exist where the maximum inundation height increases by around 30% and the beginning of inundation occurs about 2 min earlier than in the case with no seawall. On the other hand, the inundation area was almost covered in the case with no seawall.
