Summary:Kim, D.-S.; Jeong, Y.-H.; Lee, H.-Y.; Kim, D.-H., and Hong, S.-J., 2020. Using hypothetical tsunami scenarios to analyze tsunami inundation characteristics in the coastal city of Ulsan, South Korea. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1140–1145. Coconut Creek (Florida), ISSN 0749-0208. 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.
