Abstract

The preceding paper reported the survey structure of the Tsunami Evacuation Joint Survey Group for the Great East Japan Earthquake and the tsunamis vulnerable features of Yamada of Iwate prefecture and Ishinomaki of Miyagi prefecture. As the continued report, this paper introduces the analysis on the characters of the evacuees' behavior data collected by the team for Yamada and Ishinomaki of the Tsunami Evacuation Joint Survey Group for the Great East Japan Earthquake, comparing it with the same kind of data sets collected by the Ministry of Land, Infrastructure, Transportation and Tourism and the Cabinet Office. Through the analysis, it was concluded that the data collected by the team represented the general feature of the tsunami evacuation well and could be improved by the correction using age and sex distribution. It is expected that this report combined with the preceding report will provide the useful information to the users of the collected data and also provide the experience to the researchers who may do the same kind of the field survey in future.
