Monitoring the Surface Subsidence of Liupanshui City Using ALOS-2 Images and NSBAS-InSAR Technology

In recent years, the land subsidence of Liupanshui has begun to attract people’s attention. In order to grasp the current situation of land subsidence in Liupanshui city, ALOS-2 data and NSBAS-InSAR technology were selected to monitor the surface deformation of Liupanshui city. The L-band ALOS-2 SAR data is very suitable for land subsidence monitoring based on InSAR technology due to its high ground resolution, long wavelength, and short revisit period. The results show that the surface cumulative deformation ranged from −72 to 12 mm in most regions of study area. The maximum settlement is −553 mm, which is near the Shangjia Town. The areas where the settlement is obvious include Shuangdong Village, South of Muqiao Village, Dahe Town, and Junlong Mountain.
