The 6.2 magnitude earthquake in Jishishan of Linxia Hui Autonomous Prefecture in Gansu Province occurred on December 18, 2023. The earthquake caused extensive damage and collapse of town and village buildings, resulting many casualties. It is a typical small earthquake and large disaster. This paper summarizes the seismic damage characteristics and patterns of typical village and town buildings surveyed in the epicenter of the Jishishan earthquake, and analyzes typical cases based on the structural type, construction year, and whether seismic measures are used. The reasons for the severe seismic damage in this earthquake are summarized as follows: Some self-build houses have brick columns and adobe walls, but the two parts are lack of effective connections and have poor seismic resistance. This can be seen from the fact that houses with ring beams and structural columns in the same courtyard are basically intact, but houses without seismic structural measures are severely damaged. Some have varying openings on different floors, resulting in discontinuous vertical force transmission. There are many irregular planar arrangements in the structure. Partial structures are incomplete or have weak areas. Rural self-build houses are constructed according to the habits of craftsmen, without considering the stress requirements under earthquake actions, and a quality supervision system mechanism needs to be established.
