Abstract：

After　the　Ms6.4　earthquake　in　Yangbi,Yunnan,on　May　21,2021,the　seismic　damage　survey,mobile　strong　motion　observation　of　aftershocks,and　characteristic　analysis　of　ground　motion　and　building　damage　were　carried　out.The　characteristics　of　building　damage　in　the　earthquake-stricken　region　especially　in　the　meizoseismal　area　were　summarized,the　correlation　between　the　building　damage　and　the　ground　motion　characteristics　was　explored,the　effect　and　mechanism　of　topographic　condition　and　ground　motion　directivity　on　the　building　seismic　damage　characteristics　and　disaster　distribution　were　revealed.Due　to　the　topographic　effect　of　local　site,buildings　located　on　the　steep　slope　and　the　top　of　mountains　were　encountered　more　severe　damage　than　those　on　the　mountain　foot.The　directivity　effect　of　ground　motion　is　the　main　reason　for　the　damage　difference　of　buildings　with　different　orientations.By　summarizing　the　seismic　damage　characteristics　in　this　earthquake,　measurements　and　suggestions　for　improving　the　seismic　performance　of　the　mud　and　wood　houses　in　Yunnan　Province　were　proposed.　©　2023　Editorial　Board　of　Journal　of　Basic　Science　and.　All　rights　reserved.
