コンテキストを含む津波避難行動データベースの構築と迅速な避難行動を阻害する要因の分析

抄録

We surveyed victims'evacuation behaviors from the Tsunami after the Great Eastern Japan Earthquake by conducting interviews in Rikuzenntakada，Ofunato and Nodamura, Iwate and MIsawa, Aomori. Based on the information we gathered, we developed a tsunami evacuation behavior database using GIS. By adding elevation data to this database, it has become possible to display a cross-sectional view of the evacuation route. We can add tsunami inundation data to this database to determine at a glance whether evacuees have passed through the inundation area. We added information such as the reason, purpose, and background of behavior to this database so that we could understand the reason and purpose of evacuees movements. By using this database to find out the reasons for the behavior of those who did not immediately escape to the hills, we can think about how we should act to save lives in the event of a future tsunami disaster
