The evacuation to an offshore area is recognized as a method to prevent risks to fishing boats under tsunami attack. However, when the boats encounter a tsunami in areas with insufficient water depth, evacuation offshore is a dangerous method. To evacuate to the land from the sea, one must decide the fishing port and shelter for fast evacuation.
Through evacuation drills at Minamiise town, Mie, Japan, we attempted to understand evacuation time and the means of getting tsunami warnings at sea. The results of our survey were announced at some workshops, and a questionnaire for fisherman was used to discuss ways to evacuate their fishing grounds to tsunami shelters or offshore. As the result of such activities, a tsunami evacuation map for use at sea can be prepared.
