Development and Social Implementation of Smartphone App "Nige-Tore" for Improving Tsunami Evacuation Drill

This research explored how we can improve tsunami evacuation behavior which has been a major social issue since the Great East Japan Earthquake and Tsunami Disaster in 2011. We introduced smartphone app, "Nige-Tore, " for supporting tsunami evacuation drill, developed in an interdisciplinary research framework. "Nige-Tore" served as an effective interface tool which successfully visualized dynamic interaction between human action, i.e., evacuation behavior, and natural phenomenon, i.e., tsunami movement. The results of social implementation of "Nige-Tore" showed that the app was more powerful than conventional devices and methods for tsunami evacuation, such as hazard maps and drills in a traditional way without using any apps
