Outline of Final Research Achievements

With the aim of clarifying the actual human suffering caused by the Great East Japan Earthquake in Miyagi Prefecture, we conducted a study focusing on the causes of death using information on the victims of the same disaster in Miyagi Prefecture. By using the location of the bodies as the location information of the victims, the characteristics of each cause of death were clarified based on a more realistic distribution of the victims. The results of this study contribute to the clarification of the actual human casualties of the disaster, and also improve the feasibility of tsunami disaster prevention and mitigation measures based on the characteristics of each cause of death.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的価値は，これまで防災・減災分野の研究では考慮されていなかった死因を踏まえ犠牲者情報分析を行い，その特徴を明らかにした点である．このような被害実態を踏まえた対策の検討は，我が国の防災・減災を深化する上で重要である．例えば，低体温症犠牲者に関する分析では，研究により明らかになった知見を踏まえて，低体温症リスク想定フロー，低体温症リスクチェクシートのツールを開発し，研究成果の社会実装に貢献した点は，本研究の社会的意義を示している．
