| Outline of Final Research Achievements |
Extent of fatality due to natural disaster depends largely on spatial distribution of population at the moment disaster occurs. In this study, a computational model for estimating day-long spatio-temporal distribution of population is developed using a number of country-wide statistical data. The model estimates behavior of individuals by considering their attributes including age, gender, occupation, place of work, and place of residence. As a case study, the model is applied to the Keihanshin metropolitan area. Estimated maximum number of commuters unable to return home in an expecting earthquake scenario was between 1.1 and 1.9 million depending on the assumptions on traffic disruption following disaster. The model is also applied to the Kesennuma city which is struck by the huge tsunami at the occasion of the 2011 Tohoku earthquake. The result showed that the number of people in the tsunami inundated area ranges between 23,500 and 26,000 depending on the time of its occurrence.
