류큐해구 단층 지진원을 고려한 지진해일 침수예상도

초록

Recently, natural coastal hazards such as tsunamis, storm surges and sea level rising have increasingly threatened coastal communities. Among them, a tsunami may cause devastating damage not only neighboring areas but also distant areas. An effective and economic way for tsunami hazard mitigation planning is to develop inundation maps at those coastal communities vulnerable to tsunami invasions. In this study, tsunamis generated at the Ryukyu Trench zone located off the southern coast of the Korean Peninsula are investigated. A composite numerical model based on the shallow-water theory is employed to obtain inundation maps at Samchunpo and Tongyeong Ports. These maps can be used by local authorities to make mitigation plans and hazard maps against unexpected tsunami attacks.
