Geological hazard assessment is the work of investigating, monitoring, analyzing and evaluating the activity degree of geological hazards, mainly assessing the destructive capacity of geological hazards. The risk of geological disasters is reflected by various risk factors, which can be divided into historical disaster risk and potential disaster risk. The hazard of historical disasters refers to the activity degree of geological disasters that have occurred. The factors include: intensity or scale of disaster activities, frequency of disaster activities, density of disaster distribution, and intensity of disaster hazards.
