Abstract: The construction of ground projects in the Gwadar Port area of Pakistan is accelerating. However, the study of dynamic change of regional land subsidence in this area is relatively lacking. In this paper, the status and mechanisms of the land subsidence in the area are investigate by cellecting the land subsidence data which were obtained in about 6 years (from May 2017 to Apil 2023) in and around the Gwadar port area by using Multi Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) technology as well as based on Sentinel-1 data. The results indicate that in the period from May 2017 to January 2021, there was obvious land subsidence in and around the Gwadar Port area, with the maximum rate of land subsidence reaching to 20 mm/a. Beginning from January 2021, there occurred a notable land uplift in this region and the rate of the land uplift (10 mm/a) was obviously greater than that of the local land subsidence (3 mm/a). From further analyses of artificial activities and geological conditions, it has been found that although the land subcidence in this area cannot develop sustaineously in the future, some small structural damages like cracks of buildings would be possibily caused due to the existence of the uplifting caused by plate tectonic movement in this area. As a result, it is still needed to make long-term mornitoring of the ground deformation in the study area. The results of the study have a certain reference for the security maintenance of the Gwadar Port.
