Abstract: Abstract Tsunamis can cause massive damage and loss of life in coastal areas. This study uses Putuoshan Island as a case study to discuss ways to identify tsunami prevention zones based on the analysis of physical factors such as inundation, maximum wave amplitude, and tsunami flow. In the Ryukyu Trench Mw 9.0 tsunami scenario, the tsunami prevention zones of Putuoshan Island consist of land areas and marine areas. Our analysis identified two inundation areas in the western and southern Putuoshan Island as tsunami prevention zones. With the exception of the western marine area, the coastal waters of Putuoshan Island are also identified as tsunami prevention zones. The tsunami flow impact is greater in the waters of north and south Putuoshan Island. The results of this study could be used by emergency departments to take protective measures and thus to prevent the disastrous effects of tsunamis.
