Abstract
Besides the construction of sabo facilities such as sabo dams, it is necessary to inform the inhabitants of the presence of debris-flow hazard torrents and to evacuate them once debris flows are predicted to occur in order to prevent the loss of human lives due to debris flow.
Typhoon No. 19 has brought about a heavy rainfall to Uchinomi Town, Shozu-gun, Kagawa Prefecture in October, 1987. A questionnaire was carried out on the communication and application of the information on disasterprevention as well as the action taken by the inhabitants to evacuate from the debris flow. This is a report on the actual state of debris-flow warning and evacuation at that time for promoting the establishment of the system of debris-flow warning and evacuation.
