In March 2011, massive earthquake off the Pacific coast of Tohoku occurred, giant tsunami exceed expected attacked, 25,000 fishing-boats were affected. The purpose of reducing of damages of fishing-boats against tsunami, many fishermen evacuated it to the offing. But in 2011 Tohoku Earthquake, we checked the example which fishermen suffered great deal of damage. Therefore, securing of security of the fishermen against tsunami and the need of the reexamination of the correspondence policy about evacuating fishing-boat to the offing became clear some other time.
We formulated the rules of fishing-boat's evacuation to the offing the purpose of optimizing the correspondence action of it when tsunami attack, as for Ochiishi fishery cooperative fishermen in Nemuro City. The effect of the rules formulated revealed from the correspondence action of fishermen in tsunami of Chile Earthquake, 2010. But this earthquake had no shaking and lots of time to reach the tsunami, and the tsunami didn't even attack such extensive damage. Therefore, it's said that the effect of the rules formulated was limited. In this paper, we revalidated the effect of the rules formulated by grasping the action of fishermen's fishing-boats evacuation against tsunami, when giant tsunami caused by 2011 Tohoku Earthquake attacked. At the result, also in giant tsunami attacked comparatively for short time, we checked the effect of the rules formulated which many fishermen evacuated fishing-boat to the safe offing at early timing and stood by offing until the danger of tsunami became low. And we extracted the issues and policy to promote appropriate action of fishermen's fishing-boats evacuation against tsunami in the future.
