description | Western China is very susceptible to landslide hazards. As a result, landslide detection and early warning are of great importance.
This work employs the SBAS (Small Baseline Subset) InSAR Technique for detection and monitoring of large-scale landslides that
occurred in Li County, Sichuan Province, Western China. The time series INSAR is performed using descending scenes acquired
from TerraSAR-X StripMap mode since 2014 to get the spatial distribution of surface displacements of this giant landslide. The time
series results identify the distinct deformation zone on the landslide body with a rate of up to 150mm/yr. The deformation acquired
by SBAS technique is validated by inclinometers from diverse boreholes of in-situ monitoring. The integration of InSAR time series
displacements and ground-based monitoring data helps to provide reliable data support for the forecasting and monitoring of largescale
landslide. |
