The Post-Failure Spatiotemporal Deformation of Certain Translational Landslides May Follow the Pre-Failure Pattern

Investigating landslide deformation patterns in different evolution stages is important for understanding movement. Translational landslides generally slide along a relatively straight surface of rupture. Whether the post-failure spatiotemporal certain translational follows pre-failure pattern remains untested. Here, pre- and deformations Simencun Yellow River 2018 were analyzed through multi-temporal remote sensing image analysis, Interferometric Synthetic Aperture Radar (InSAR) monitoring intensive field investigations. The results show that spatial both follow retrogressive failure pattern. long time series displacement before after characterized by obvious seasonal periodic stage acceleration movements. Effective rainfall played an role increase acceleration, change temperature might have accelerated displacement. Finally, there possibility does when conditions are satisfied. great significance to improving our risk prevention control.
