Abstract

In recent years, a wide-area disaster causing enormous damage has occurred almost every year in Japan. The authors have been involved in the management of disaster volunteer centers in various places and have realized the difficulty in coordinating the actual number of activities in disaster-stricken areas and the required number of disaster volunteers. The number of disaster volunteers required varies greatly on a daily basis. The number of volunteer activities often depends on the quantity of disaster waste created from damaged houses. Accordingly, if the quantity of waste was grasped immediately on the spot, the number of disaster volunteers required in the short term could be estimated. In this study, the actual conditions in Hitoyoshi City, Kumamoto Prefecture, at the time of the Heavy Rainfall in July 2020 are considered as an example, and the method is considered to immediately grasp the quantity of waste to be disposed of and the number of people required for this task. We compared the amount of waste disposal work estimated from the in-vehicle camera image with the number of active residents and volunteers. As a result, it was estimated that 40–50% of the work was carried out by volunteers at the peak of volunteer activities.
