Abstract: Based on the seismic hazard risk survey and geological hazards survey in Chuxiong Yi Autonomous Prefecture, the ArcGIS spatial analysis and mathematical statistics were used, the relationship between the seismicity and the development of geological hazards is discussed from the aspects of seismic geological hazards, seismic intensity, seismicity and the evolution of geological hazards after earthquakes. The results show that the main geological hazards triggered by earthquake are landslide, collapse and ground fissure, especially in the high intensity or low intensity crossing area of the earthquakes above magnitude 6. The earthquakes below magnitude 6 can not trigger the geological disasters or trigger the geological hazards to a lesser extent, but they can promote the development of geological hazards. After the earthquake, geological hazards have long-term activity. The magnitude 6.5 earthquake in Wuding County led to sustained geological disaster activity for 23 years, while the magnitude 6.2 and 6.1 earthquakes in Dayao County led to sustained geological disaster activity for 18 years. In future post-earthquake reconstruction in Chuxiong Yi Autonomous Prefecture, full consideration should be given to the long-term activity characteristics of post-earthquake geological hazards in order to avoid loss of life and property.
