Abstract

<p> Numerous combinations of disaster reduction facilities should be taken into consideration to evaluate the damages of inundation due to probabilistic tsunami hazard. In this study, we implemented it and investigated how the tsunami inundation probability changes by using the levee fragility model. coRaL method was used to obtain the inundation depth exceedance probability and applied to two different terrains. The results showed that the probability was between the case of overtopping and collapse and the case of overtopping but no breach, which was found to be reasonable, and they support the effectiveness of levee fragility model.</p>
