The guideline issued by the Fisheries Agency prohibits fishing-boats from evacuating to the offing. While the present fishing insurance almost insure fishing-boats hit by tsunami, it doesn't insure life during suspension at all, the fishermen bear big burden economically. Therefore many fishermen evacuated fishing-boats to the offing to protect them, but we find some problem fishermen don't have enough knowledge of tsunami. In this study, we practice the survey of fishermen's consciousness and actual fishing-boat's evacuation, and we build rules of fishing-boat's evacuation and communication method, to promote fishermen's correct knowledge of tsunami and to evade evacuation on dangerous situation.

Tsunami simulation for education was developed, this simulation helps a fisherman to acquire basic knowledge of tsunami and make a decision of fishing-boat evacuation against tsunami. Tsunami simulation is based on the simplified bathymetry, so specific knowledge of tsunami is effectively instructed. A lecture on tsunami disaster prevention for fishermen was held, and developed tsunami simulations were shown. As a result, fisherman's knowledge of tsunamicharacteristic was improved, so an education effect was confirmed. The fishermen who understood knowledge of tsunami correctly perceived the risk of tsunami and understood knowledge of fishing-boat evacuation. This study showed that the acquiring knowledge of tsunami contributes to be careful in decision-making of the fishing-boat evacuation.

Simulation system for help of the fishing-boat evacuation assessment against tsunami was developed. This system combines tsunami simulation, tsunami warning simulation and fishing-boat evacuation simulation. Therefore this system is able to analyze temporal alteration and spatial relevance of each event. For this framework, developed system can help to size up the fishing-boat evacuation for safety against an impending tsunami. As for test case, we applied the system to Ochiishi fishery harbor. An actual fishing-boat evacuation survey for safety was carried out, and evaluated the fishing-boat evacuation. As a result, this system was confirmed to function effectively as help of the fishing-boat evacuation assessment.
