Conventional geodetic methods rely on point measurements, which have drawbacks in detecting and tracking geologic disasters at specific locations. In this study, the estimation of ground surface deformation in economically important urban regions of Pakistan's southern coast from 2017 to 2022 is performed using interferometric SAR technique. Vertical displacement which was used to investigate the potential correlation with the most effective causative parameters of deformation. The densely populated areas of the study area experience annual subsidence of 130 mm, and the western less populated region experiences an uplift of 70 mm annually. The densely populated areas of the study area experience an annual subsidence of 130 mm, and the less populated western region experiences an uplift of 70 mm annually. Land deformation varies along the coast of the study area, where the eastern region is highly reclaimed and is affected by erosion. The results obtained on a Sentinel-1 SAR dataset indicate that there is significant subsidence in the major urban districts. A linear PS-InSAR approach is required to address the ground movement activities acutely, and it will make it possible to plan surface infrastructure and handle issues brought on by subsidence more effectively. This information is crucial for coastal management, hazard assessment, and planning sustainable development in the region.
