Analysis of major tsunami prevention areas in Zhujiajian Island of China

Tsunami hazard is very harmful and needs to be prepared in advance. Zhujiajian Island is located on the coast of the East China Sea, facing a serious tsunami risk. Based on the tsunami numerical calculation, this paper analyzed the major tsunami prevention areas of Zhujiajian Island. Two types of objects, which were important facilities and population distribution, were considered for the analysis of major tsunami prevention areas. In this paper, important facilities such as residential areas, tourist areas, bathing beaches, schools, airports, docks, chemical industry areas, and hospitals are all considered. The analysis results can be used for identifying high-risk areas, formulating tsunami disaster mitigation plans, making more detailed tsunami risk analyses, and rationally distributing disaster reduction resources.
