ANALYSIS ON THE ACTUAL VESSEL MOVEMENTS UNDER TSUNAMI BY AIS DATA

Abstract

 Drifting vessels in ports under Tsunami can worsen damages to the ports, by causing collisions between vessels or vessels running aground on piers. The Japanese Ministry has been implementing an initiative to facilitate emergency evacuation of vessels from ports, thus it is significant to examine water facilities for such quick evacuation by referring to the actual vessel movements under Tsunami.

 The purpose of this study is to provide a good reference for ports to examine measures to support smooth evacuation, by analyzing vessels movements (from the occurrence of the Eastern Japan Great Earthquake until the completion of the evacuation) observed at Tomakomai, Kashima, and Kawasaki ports, under the utilization of AIS data.
