Outline of Final Research Achievements

Hazard maps have been created to inform citizens of the disaster risks, but the victims due to delayed escape have not disappeared. There is a need for a way to provide disaster risk information closer to the living people. This research developed the "Safety of Life (SOL) Visualization Application," a smartphone application that records disaster risk linked to an individual's travels and visualizes high-risk times and locations by combining information from publicly available hazard maps with location information from smartphones. Four levels of indices have been developed for earthquakes, floods, landslides, and other disasters, enabling users to know which disasters they should be aware of. The project was not carried out as planned due to the COVID-19, but the utilization was verified in the Tokyo metropolitan area and the Nankai Trough area, etc. Research will be continued after the end of the project year.

Academic Significance and Societal Importance of the Research Achievements

ハザードマップを携帯端末の位置情報と紐づけて閲覧できるサービスの開発や研究は既に存在しているが、ライフログのように時系列で記録し可視化したものはない。またユーザーによる利用検証から、個人に対する災害リスクの高まりを時空間的に可視化することで、組織の防災対策や事業継続の検討にも有効であることが示唆された。特に大型の台風の接近時や南海トラフ地震臨時情報が発表された時の対応検討への活用が期待できる。
