Implication

Field investigations reveal significant surface deformation in the Lumei landslide, indicating important monitoring insights for infrastructure safety.

Key Points

This research aims to characterize deformation patterns of the Lumei landslide in the Tibetan Plateau using advanced InSAR techniques.
Conducted field investigations in Cuomei County.
Collected Sentinel-1A SAR data across 84 scenes (2017-2023).
Applied PS-InSAR and SBAS-InSAR methods for time-series monitoring.
Comparatively analyzed surface deformation results from both techniques.
Surface deformation rates from PS-InSAR range from −36.55 to −21.81 mm/yr; SBAS-InSAR shows rates from −30 to −10 mm/yr.
Significant spatial heterogeneity in deformation values is observed, decreasing outward from the center.
Both methods indicate a subsidence trend along the line-of-sight (LOS) direction, demonstrating strong spatial consistency.
