After the East Japan great earthquake disaster occurred, it came to be predicted that the tsunami which was considerably huger than a previous assumption. It was pay attention to the hybrid refuge technique that was used together with the floating type tsunami evacuation shelter in addition to conventional high place refuge. The behavior of the shelter is divided into 3 patterns in previous study.
In this study, data was put in order by the Froude number and the wave force was measured to act on a shelter. Then it was performed an evaluation for the refuge using the shelter. Therefore, Pattern 1 was stable from photointerpretation and behavior analysis, and patterns two or three was unstable. However, Pattern 1 was shown great value from wave force, it was thought the risk that a shelter was destroyed. In addition, pattern two or three shows a relatively small value. From these reason, examination of the most suitable setting position will be important in the future.
