Perspectives on the Prediction of Catastrophic Slope Failures from Satellite InSAR. IEEE Transactions on Geoscience and Remote Sensing, 40(11): 2375-2383. A New Algorithm for Surface Deformation Monitoring Based on Small Baseline Differential SAR Interferograms. The results can provide a reference for the prevention and control of landslide risk in Zhouqu County.īerardino, P., Fornaro, G., Lanari, R., et al., 2002. It is found that the deformation velocity of landslides in this area is mainly affected by rainfall and there is a lag effect. The deformation characteristics of four typical landslides are analysed in detail using deformation velocity and rainfall data. The surface deformation areas detected by SBAS-InSAR were verified by optical remote sensing image interpretation and field investigation, and a total of 23 active landslides were identified finally. Small baseline subset interferometry synthetic aperture radar technology (SBAS-InSAR) was adopted to identify the potential active landslides in the surrounding area of Zhouqu County, using ascending and descending orbit Sentinel-1 satellite images taken from October 2017 to December 2018.
On July 12, 2018, a landslide blocked the Bailong River near Zhouqu County, posing a serious threat to the life and property of local residents and the safety of infrastructure. Zhouqu County in Gansu Province, Northwest China, is typically highly prone to landslides.
