云南是一个新构造运动复杂，地震活动强烈的地区。自有地震记载以来，该区共发生７—７．９级地震１６次，８级地震１次。通过对云南新构造运动特点分析该区新构造运动分区现象及年代学差异明显，全新世断裂活动主要集中在新构造单元边界断裂和新构造运动强烈地区的较大规模的断裂上，这些断裂大多是７级以上大震的发震构造。 Yunnan is a newly tectonically complex area with strong seismic activity. Since its own earthquake records, there have been 16 earthquakes of magnitude of 7-7.9 in this area and one earthquake of magnitude 8.0. Through the analysis of the characteristics of neotectonic movement in Yunnan Province, the zonation and geochronology of neotectonic movement are obviously different. The fault activity of the Holocene mainly concentrates on the larger-scale faults of the boundary between new tectonic units and intense neotectonic movements. Most of these faults It is the seismogenic structure of earthquakes above magnitude 7.
