Abstract

In Hiroshima city, debris flow occurred at 166 places due to the heavy rainfall on 20 August 2014 and the death toll reached 74. We carried out questionnaires to the fire fighters belonging to Hiroshima City who worked against the sediment disaster, in order to study the needs about disaster mitigation technologies. The answers to the questionnaires were analyzed by KHcoder, a text mining methods. As a result, it was found that five kinds of disaster mitigation technologies were required by fire fighters, namely, Intelligence sharing of damage situations, Understanding situations with a birds eye view at rainy and night, Airing of evacuation instruction and information service to local residents, Understanding dangerous situations using alarm to active fire fighter, Demanding weather information and acquisition tools. Regarding the way of information sharing, it was pointed out the importance to establish a system for information acquisition and sharing in each corp.

広島県広島市では，平成26年8月豪雨により市内166か所で土石流が発生し，74名が犠牲となる甚大な災害が発生した。土砂災害時に活動した広島市消防局の消防職員に技術開発に関する要望についてアンケート調査を実施した。この回答を，テキストマイニングの手法の一つであるKHcoderを用いて解析した結果，5つの消防防災技術の整備が今後必要であることが分かった。また，情報共有のあり方に関しては，隊ごとの情報取得と情報共有の仕組みを整備する重要性が指摘された。
