In this study, the authors considered the utilization of information systems in the collection, aggregation, and management of damage information necessary for disaster assessment, as a case study on the disaster damage assessment of public civil engineering facility in the 2016 Kumamoto Earthquake. For the information collection, aggregation, and management on damage to public engineering facility, which has been conducted since the Kumamoto earthquake occurred, the work-flow was that each Promotion Bureau in Kumamoto Prefecture aggregated the information collected by patrol members, and they reported the aggregated information to its River Division. In the beginning, the information was reported on paper and photographs, and it was necessary to input and organize the information again when the higher-level organization compiled it. Therefore, an information system based on Web-GIS was introduced and utilized to collect, consolidate, and manage the information collected by the patrol members in a centralized manner, and to facilitate the utilization of the consolidated information by its Promotion Bureau and the Prefecture. Unstructured interviews with prefectural officials pointed out that the use of the information system reduced the burden of inputting and organizing damage information, and that proper information management may enable efficient responses to external organizations. On the other hand, when introducing a Web-GIS-based information system, the problems of setting user permissions for viewing and editing, the image of using the system in relation to actual disaster assessment, and the linkage with other systems were identified as issues that cannot be solved. This will become a necessary condition for the introduction and utilization of such information systems.
