[SVC30-P07] Disaster Prevention Use of Climber Dynamic Data
Keywords:Climber dynamic data, Mt. Fuji, Mt. Ontake, Mt. Nasu
In recent years, especially since 1980s, there has been a climbing boom in Japan, and many people are enjoying climbing. Among the mountains to be climbed in Japan, there are many active volcanoes that can be approached by climbers to the vicinity of the crater. In the tragic disaster of Ontake Volcano in 2014, it was difficult for local governments to grasp whereabouts of climbers and to conduct rescue and search for victims. The same issue was raised also in the 2019 eruption of Kusatsu-Shirane Volcano. Therefore, it is quite important to grasp whereabouts of climbers in the event of disaster for proper decision of rescue and search. In addition, by grasping the dynamics of climbers from normal times, local governments will be able to formulate evacuation plans based on more realistic back data.
Several experimental efforts to acquire climber’s dynamic data have conducted in Mt. Fuji, Mt. Ontake, and Mt. Nasu. We called them “Mt. Fuji Challenge”, “Mt. Ontake Challenge”, and “Mt. Nasu Challenge”, respectively. In the efforts, we distribute small beacons to climbers, and receivers which are set in mountain trails detect signals from the beacons, then we can grasp the number and location of climbers who have the beacons in real time. After processing the acquired climber’s data, it is possible to grasp the congestion status of mountain trails and the behavioral characteristics of climbers and tourists.
To share the acquired data with stakeholders including local governments and climbers, we developed a visualization tool of the climber’s data. By combining the acquired climber’s data using the tool with hazard information such as hazard maps, it is possible to evaluate the exposure of climbers to various eruption hazards, that is, to estimate human damage.
In the emergency drill with Mt. Nasu Volcano Disaster Prevention Council in this year, we made a scenario based on the results from Mt. Nasu Challenge 2020. By comparing the results obtained in the Mt. Nasu Challenge 2021 and the results obtained in other volcanoes (Mt. Fuji and Mt. Ontake), we are studying the standardization of disaster prevention use of climber’s dynamic data.
