    Abstract: The landslide is one of the most common geological hazards in nature, the rapid development of unmanned aerial vehicle (UAV) technology and virtual reality (VR) technology provides important data resources and technical support for immersive simulation and visual analysis of the landslide. Firstly, this paper focuses on the dynamic construction and exploratory analysis of VR scene in landslide hazard, then some key technologies such as diversified organization of landslide data, dynamic fusion visualization of VR scene are addressed in detail, thus a VR scene interaction method based on handle ray is proposed. Finally, a prototype system is implemented and a case study region is selected for experimental analysis. The experimental results show that the proposed method can dynamically construct landslide VR scene based on UAV remote sensing data, and can support the user to carry out immersive interaction and disaster information analysis.
