Abstract
<p> We propose the coRaL method (a method of incorporating Random phase model into Logic tree approach), which is a probabilistic tsunami hazard assessment method with a high objectivity by reforming the evaluation method of earthquake asperity model and the concept of aleatory uncertainty among the probabilistic methods using logic tree approach conventionally used in Japan. The proposed method is applied to the cities located along the Pacific coast where the tsunami risk due to the Nankai Trough megathrust earthquake is assumed. We show that the proposed method can evaluate the tsunami inundation depth distribution for each return period (e.g., 150 years, 500 years, 1000 years, 2500 years), and for each percentile considering the uncertainty of tsunami hazard assessment even for the same return period.</p>
