Because Japan is prone to mega earthquakes and tsunamis, including the anticipated Nankai trough earthquake, the team developed an evacuation drill app for residents to stress the importance of emergency evacuation as the most effective measure for minimizing casualties. This app uses trusted flood simulation data from researchers and indicates the safety level in an emergency evacuation during tsunami using graphical representations, sound effects, and announcements. It is designed to help users think of emergency scenarios and measures through simulated experience that includes more than simple on-screen tsunami predictions. GK Kyoto’s main responsibilities include app UI design, public relations support, store up release, and corporation during test run.
