In response, a tsunami alert, a tsunami warning and an advisory were issued for the entire Pacific coast region. This research investigates the evacuation behavior of ships by AIS （automatic identification system） data in Onahama port after the tsunami warning was issued. The unusual behavior observed was attributed to the emergency evacuation of ships. This research investigates the evacuation behaviors of the vessels using the data obtained from AIS, around the Onahama Port during alerting the major tsunami warning. The result shows that most vessels in the port started evacuating approximately 10 min after the major tsunami warning and completed offshore evacuation 40 min after this warning. This contributed in understanding the actual status of the vessel evacuation. In addition, the travel paths of each vessel revealed the influence of the tsunami on the vessels. Furthermore, the exceptional situation where several vessels moved in the same direction at the speed almost same for about 2 hours was confirmed. As a result, it can be estimated that the waves that affected both vessels were the drawback of the tsunamis.展开更多

In this paper, the authors analyze who purchased more bottled water after the earthquake using Quick Purchase Report data. The results are as follows： first, consumers who before the earthquake tended to purchase less bottled water tended to increase the volume purchased after the earthquake; second, the motives for purchasing bottled water after the earthquake differed between consumers in the Tokyo and Osaka metropolitan districts.展开更多

The paper examines the damage of tsunami affected areas and analyses the damage to extract lessons in order to safely reconstruct the affected areas from the view point of building regulations such as ＂Disaster Risk Area＂ provided by the Article 39 of the Building Standard Law and the Urbanization Control Area and UPA （Urbanization Promotion Area） provided by the Article 8 of the Ordinance of the City Planning Law of Japan.展开更多
