We carry out experiments to grasp the movement of climbers as well as an experiment to share the disaster situation with related organizations in real time, at Nasudake in 2020 and Ontakesan in 2022. In the experiments, small beacons are distributed to many climbers, and their movements are detected by receivers installed on mountain trails in advance. We build an online viewer to visualize the monitoring results on a web map in real time, and share them with the related organizations, and exchange opinions with them about the use of the acquired data for disaster prevention. Based on the results of the experiments, we consider how to solve problems related to volcanic disaster prevention. It is shown that the systems used in the experiments leads to solutions to problems related to volcanic disaster prevention during not only disasters but also normal times, such as updating drills and revising evacuation plans.
