STUDY ABOUT IMPROVEMENT IN SECURITY OF SHIPS AT PORT AND HARBOR AGAINST TSUNAMIS

Tsunamis caused by large-scale earthquake are considered imminent in Japan, and damage to port and harbor by tsunami is possible. Ships at port and harbor may be damaged, and ships may turn into the tsunami debris. This paper describes the countermeasure against tsunamis at port and harbor about ships. In the past, ships were damaged by tsunamis several times. Countermeasures against tsunamis could be considered by analyzing literatures about ship damage. And the investment of countermeasure requests a large amount of money, the study of scale is needed. This paper describes also about this matter. This study is useful for making countermeasure against tsunamis about ships, and this study shows the future works of the port authority and many researchers.
