CHARACTERISTICS OF DISASTER-RELATED INFORMATION IN CASE OF THE HEAVY RAIN EVENT OF JULY 2018 ―A CASE STUDY OF OKAYAMA, HIROSHIMA, AND EHIME PREFECTURES―

摘要

?This study presents the characteristics of disaster-related meteorological information and evacuation protocol based on a case study of the heavy-rain event of July 2018. By clarifying their characteristics, this enables us to obtain policy implications for municipalities and residents to respond appropriately to imminent heavy-rain hazards. As a result, it was found that many municipalities did not issue the evacuation preparation protocol. In addition, the proportion of residents who received the evacuation protocol in the order of the evacuation preparation, the advisory, and the order, was less than 50% of the residents targeted by the order. Moreover, the national government recommends that municipalities should associate their issuance of evacuation protocol with the meteorological information; however, there were differences in the utilization of the meteorological information between the municipalities.
