Abstract We take Xi’an-Xianyang region as the study area and use Sentinel-1A satellite data covering the study area from June 2015 to January 2023. Using time-series InSAR as the main technical means, combined with other data, we obtain information such as the distribution characteristics and deformation velocity of land subsidence in Xi’an-Xianyang area, and analyze the laws of land subsidence occurrence and evolution. The results show that the results obtained by SBAS-InSAR and StaMPS-InSAR are basically consistent. The ground deformation areas in Xi’an are mostly central and southern, and the main factor of deformation is groundwater exploitation. The distribution and trend are influenced by ground fissures and faults. Most areas of Xianyang are in a stable state, with only some areas experiencing significant deformation, which is influenced by various factors such as groundwater exploitation and urban construction.
