Evaluation of Geological Hazard Susceptibility Based on InSAR
In this paper, the SBAS-InSAR technique was firstly used to obtain the surface deformation information of the study area from January 2019 to August 2021 based on Sentinel-1A data. Then the weights of the eight evaluation factors were obtained by Ana-lytic Hierarchy Process (AHP). Finally, the results of the susceptibility evaluation were obtained and analyzed by using a comprehen-sive evaluation method based on ArcGIS platform. The results show that surface subsidence mainly occurs in the central part of the study area; the high susceptibility areas of geological hazards are mainly located in the central part of the study area, while the eastern part is mainly of medium susceptibility and the western part is mainly of low susceptibility.
