Summary:We developed a small Tsunami shelter. The design characteristics of this shelter are, its floater keeps the shelter floating even if the cabin space is fully flooded, the shelter can be self-recovered from the upside down situation when it rolls in the sea. When the shelter is washed away from the shore, it starts drifting. In that case, passengers might have to stay in the small cabin for several days. The length of the shelter is around 2m, which is much less than a typical life boat. So we carried out the first sea experiment using a real shelter with riding 8 passengers. In this paper, we’ll show the experimental results of motion sensor, towing force, as well as lessons learnt.
