説明

During the 2011 off Pacific Coast of Tohoku Earthquake Tsunami, large vessels that could not escape to safe fields in the tsunami-affected areas were helplessly transported by tsunami-induced currents. The positions of a transported vessel in time are analyzed from the data obtained with the Automatic Identification System (AIS) which large vessels are obliged to install by the International Convention for the Safety of Life at Sea. The AIS data on the vessels in the Port of Kashima during the tsunami is utilized for numerical simulation of the tsunami-transported vessels in the port. Further, validation of the numerical simulation with the AIS data demonstrates problems on the numerical simulation of tsunami-transported large vessels.
