The Daguangbao landslide (DGBL), triggered by the 2008 Wenchuan earthquake, is a rare instance of super-giant landslides globally. post-earthquake evolution DGBL has garnered significant attention in recent years; however, its deformation patterns remain poorly characterized owing to complex local topography. In this study, we present first observations surface dynamics integrating satellite- and ground-based InSAR data complemented kinematic interpretation using LiDAR-derived Digital Surface Model (DSM). results indicate that maximum line-of-sight (LOS) displacement velocity obtained from satellite approximately 80.9 mm/year between 1 January 2021, 30 December 2023, with downslope velocities ranging −60.5 69.5 mm/year. Ground-based SAR (GB-SAR) enhances detecting localized apparent at rear edge landslide, LOS reaching up 1.5 mm/h. Our analysis suggests steep rugged terrain, combined fragile densely jointed lithology, are primary factors contributing ongoing landslide. findings study demonstrate effectiveness combining systems, highlighting their complementary role interpreting deformations.
