Probabilistic tsunami hazard analysis (PTHA) is based on the approach of probabilistic seismic hazard analysis (PSHA) which isperformed using various seismotectonic models and ground-motion prediction equations. The major difference between PTHA and PSHAis that PTHA requires the wave parameters of tsunami. The wave parameters can be estimated from tsunami propagation analysis. Therefore, a tsunami simulation analysis was conducted for the purpose of evaluating the wave parameters required for the PTHA of Uljinnuclear power plant (NPP) site. The tsunamigenic fault sources in the western part of Japan were chosen for the analysis. The waveheights for 80 rupture scenarios were numerically simulated. The synthetic tsunami waveforms were obtained around the Uljin NPP site. The results show that the wave heights are closely related with the location of the fault sources and the associated potential earthquakemagnitudes. These wave parameters can be used as input data for the future PTHA study of the Uljin NPP site.
