Damage to the Hanazawa Preservation District for Groups of Traditional Buildings in Yaizu City by Typhoon No. 15 in 2022 and the Effects of the Preservation and Improvement Operations on Disaster Mitigation

Abstract

This study examines the damage survey of the Hanazawa Preservation District for Groups of Traditional Buildings in Yaizu City, which was damaged by a typhoon. In the damage survey, questionnaires and interviews were conducted to clarify the damage situation at that time and the awareness and behavior of the local residents. The structural soundness of traditional buildings damaged by the landslide was assessed through visual surveys and microtremor measurements. Based on these findings, it was shown that the preservation and improvement operations in the Preservation District functioned organically not only for cultural properties protection, but also for community disaster mitigation.
