Seismic landslides will bring great damage to the natural environment and people's lives. To evaluate and judge the extent of seismic impact on slopes in a large area, the risk assessment method of potential earthquake-induced landslides with predictive properties is mainly adopted. It is of great significance for engineering construction and disaster prevention to deeply study the basic theory of seismic slope hazard analysis and to draw the actual hazard distribution map. The research progress of data for seismic hazard analysis of slopes with predictive properties is reviewed. The data for evaluating slope seismic risk with permanent displacement method can be classified into three types: (1) The judgement basis of slope failure degree under the influence of earthquake; (2) Regional ground motion parameters, such as peak acceleration and Arias intensity; (3) The basic parameters of slope, such as cohesive force, friction angle, gravity, slider thickness, and slope angle. The accuracy of slope seismic risk assessment is related to the depth and accuracy of the three kinds of data. The research status and application of the three types of data are described in detail. Finally, some problems in the theory and the future research directions are analyzed.
