Although the landslide scale and behavior significantly affect the tsunami water level, various analysis methods with different theories and parameters have been proposed. Since there are few examples of comprehensively verifying the characteristics of methods and their impact on tsunami evaluation, this study focuses on understanding the impact on tsunami water level evaluation and compares typical software and analysis methods. Verification using benchmark problems and comparison with hydraulic experiments are performed, and three-dimensional analysis using a spherical slip surface is considered appropriate for slope stability analysis. In addition, regarding landslide behavior, it is concluded that the appropriate setting of general parameters, such as bottom friction, is more important than the differences between software.
