To establish a tsunami disaster prevention plan, including prior risk assessment and damage reduction for Ulsan in South Korea, a hypothetical scenario-based tsunami inundation simulation for 12 emergency evacuation areas was designed, and the inundation characteristics of the tsunami were analyzed. A hypothetical source 01 tsunami combined with a magnitude 9.0 earthquake affected the evacuation areas most significantly, while a hypothetical source 11 tsunami with a magnitude 7.5 earthquake had a relatively minor impact on the areas. In the Ilsan area of Ulsan, the hypothetical scenarios exhibited minimum and maximum inundation depths of 0.5 m and 6 m, respectively, and a maximum inundation area of about 206 km². The tsunami inundation characteristics of the Ulsan area analyzed in this study will be useful for establishing an emergency action plan and countermeasures for tsunami situations.
