AbstractTsunamis are one of the most destructive natural phenomena (Pugh and Woodworth, 2014). For past decades, the risk of potential earthquake zones has been issued by Japanese researchers, which could occur tsunami, in Niigata and Tottori area located in the west coast of Japan and the Ryukyu trench located in Okinawa as well (Disaster Prevention Research Institute, Japan). Also, there is a Yamamoto Rise on the East Sea, where it strongly affects tsunami propagation. This topography causes high tsunami energy to concentrate on the east coast of Korea (Cho and Lee, 2013). For example, the 1983 Akita and 1993 Hokkaido earthquake induced tsunamis, Japan, respectively cause the property and life damages to the certain cities on the east coast of Korea. Therefore, it is important to propose the optimal deployment location of offshore tsunami observation instruments to contribute to the tsunami early warning system by increasing probability of tsunami detection with the minimal number of instruments considering a large number of potential tsunami scenarios. In this study, by considering various factors, the optimal location of instruments is suggested based on the numerical model results of possible tsunami scenarios.
