The application relates to a dynamic visualization method and device for earthquake disasters. The method comprises: acquiring initial point cloud data of buildings and scenes in a target area; acquiring shake displacement data varying with time of the buildings by simulating an earthquake excitation on the buildings and the scenes; performing voxel downsampling and point cloud segmentation and extraction on the initial point cloud data to determine a ground point cloud and a point cloud of each building; updating in real time coordinates of each point of the point cloud of each building according to the shake displacement data; and rendering in real time the ground point cloud and the coordinates of each point of the point cloud of each building to generate a dynamic visual image for displaying.
