  • Based on the characteristics of surface geological hazards caused by the 1933 earthquake in the Diexi earthquake area upstream of the Mingjiang river, the authors conducted a systematic analysis of the distribution characteristics of slope deformation-failure in the Diexi high earthquake intensity area. Four types of slope deformation-failures were observed in the Diexi area. Mechanisms of slope deformation-failures were then developed based on the relationship between initiation of earthquake and stress fields in the Diexi area. Different types of slope deformation-failures fully reflect various impacts of the earthquake at different locations. It is concluded that the endogentic geological process controls the occurrence of the epigenetic geological disasters.
