Backgrounds and Mitigation Method toward Rapid Increase of Climbing Incidents by Analyzing Mountain Incident Records of Nagano Prefecture Police

Abstract

This research investigated rapid increase of climbing incidents in Nagano prefecture to grasp background of the increase and to mitigate these incidents. The mountain incident records of Nagano Prefecture Police was used to analyze the trend and backgrounds of rapid increase of incidents. As a result, increase of number of climbers and rise of probability of incidents were presumed main reasons of recent rapid increase of incident number. Referring indications of the previous studies, the results by analyzing referred indicators showed that combination of mountain region with high difficulty and low level competence against risk was estimated to make higher probability of occurring incidents. Therefore, it was considered to be necessary to create a new public relation method for matching climbers’ competence and the difficulty of each climbing route.
