In order to simulate an occurrence process of tsunami induced by a slope failure due to an earthquake, it is required to treat an elastoplastic analysis for slope failure, fluid analysis and fluid-elastoplastic interaction in the numerical model. Therefore, in this study, by using the particle method which is suitable for an analysis on large deformation of soil and complicated water surface change, the fluid-elastoplastic hybrid model is developed to simulate a complicated process of a slope failure induced tsunami. In this model, an elastoplastic analysis including large deformation of soil and a fluid analysis are unified.
