Based on materials of field investigation and geological hazard situation inspection after Wenchuan earthquake, in this paper, from the aspects of geological hazard case and dangerous case, the authors analyze case distribution, type, grade of geo-hazard triggered by Wenchuan earthquake. Furthermore the authors give an evaluation of geo-hazard triggered by Wenchuan earthquake in Shaanxi Province compared with in Sichuan and Gansu Province, in the end trend of geo-hazard in Shaanxi Province is predicted preliminary. The geological hazard case and danger cases have the following five characteristics: First, geological hazard and danger case mainly distributes the extension of Longmenshan Mountains geological structure. Second, geological hazard case type is mainly landslides. Third, geological hazard-causing object is mainly institution and schools. Fourth, small grade of geological hazard cases is the largest in all hazard cases. Fifth, relation of geological hazards in scale and geological hazard grade is the “U” shaped relationship. Damage caused in Shaanxi Province by Wenchuan earthquake is relatively light than which of Sichuan and Gansu Province. Shaanxi Province is one of serious provinces in geological hazard, so the frequency of geological hazards could be increased in the future.
