Abstract Aiming at the inconsistency of deformation characteristics of two large landslides in Guxue town, Deyong county, obtained from Sentinel-1A data of ascending and descending orbits, we study the applicability of InSAR technology for landslide monitoring in this area by using R index, sensitivity, and coherence parameters. The results show that the descending data is more suitable for the identification and monitoring of the two large landslides than the ascending data and can explain the reason of the inconsistency of the landslide results. We undertake time series deformation analysis and multi-dimensional deformation feature decomposition for the two landslides. The results show that the maximum cumulative deformation values of the two landslides from 2019 to 2020 are about 300 mm and 230 mm, respectively, and more attention should be paid to them.
