Abstract: Geological hazard susceptibility evaluation in Qingyang County was carried out using the information model method. Firstly，the data source is processed，and five evaluation indicators are select⁃ ed，topography（slope and terrain relief），geological environment（engineering rock formation，fault buf⁃ fer），and human activities（road buffer）. The weights of the five evaluation factors were calculated by the AHP method，and the five types of information evaluation layers and the disaster points were superimposed and analyzed by the ArcGIS platform to obtain the susceptibility index. The natural breakpoint method was used to reclassify the susceptibility index，and the study area was divided into four categories: high-risk ar⁃ ea，medium-prone area，low-risk area，and non-prone area，which provided basic data for geological di⁃ saster risk zoning and prevention zoning.
