가능 최대지진해일에 의한 재해정보도

Abstract

During last decades, several major earthquakes and subsequent tsunamis have been occurred in the East Sea surrounded by Korea, Japan and Russia. These tsunamis caused devastating damage to coastal areas not only in Japan but also along the Eastern Coast of Korea. It is important to establish a countermeasure against tsunamis based on fundamental researches, such as field survey and numerical simulation. In this study, a concept of probable maximum tsunami is firstly proposed. The probable maximum tsunamis are consisted of 3 historical and 11 virtual tsunamis. An inundation area is then predicted based on probable maximum tsunamis and a tsunami hazard map is also produced. The produced tsunami hazard map can be used by the local authority in the event of real tsunami attacks.
