In the case of emergencies such as natural hazard disasters, it is important to share various information as quick as possible. To comprehend the situation, we should quickly share the information about when, where, and who. These processes are typically performed using a GIS technique. Asian Disaster Reduction Center developed a combined SNS with GIS information-sharing tool (Chuang et al., 2019, EGU General Assembly 2019 abstracts), which we applied to a volcanic disaster drill.
The Yamanashi Prefectural Police conducted a drill on November 28, 2024, assuming the evacuation of tourists in the event of a Mount Fuji eruption. This drill primarily involved tourism-related businesses and aimed to identify key issues related to tourist evacuation.
During the drill, various measures were implemented, such as relocating police station functions to a safer location and transporting tourists via buses and boats. Police officers and participants acting as tourists were instructed in advance to have an information-sharing app ready on their smartphones, and they were encouraged to use it for communication during the drill.
More than 100 posts were made during the drill, and the organizers also tested sending alert notifications via push messages through the app. After the drill, participants were interviewed about their experiences, and their feedback was generally positive.
