Outline of Final Research Achievements

In this research, we examined the framework of early detection of tsunami on land using AIS data automatically transmitted by merchant ship and so on.First of all, we modeled the motion of the ship being tumbled by the tsunami. Next, by successive data assimilation, we attempted to estimate the tsunami velocity inversely from ship motions using the actual ship data obtained in the Great East Japan Earthquake and the developed model. As a result, it was shown that the tsunami velocity can be estimated inversely from ship motions data, although some problems remain. In addition, we made a database of the details of vessels sailing around Japan and constructed a system that identifies ship's items from the identification number transmitted by AIS data.
