摘要

This study applies the persistent scatterer interferometric synthetic aperture radar (PS-InSAR) technique to investigate surface deformation in Makkah City, Saudi Arabia, a region undergoing rapid urbanization and characterized by complex geological conditions. The rationale for this research stems from the extensive anthropogenic activities in Makkah City, such as groundwater over-extraction, large-scale construction projects, and significant land-use changes, which may lead to surface deformation and pose potential risks to infrastructure and public safety. Utilizing 16 C-band Sentinel-1 satellite images acquired from the European Space Agency (ESA) between December 2017 and January 2019, we employ the StaMPS code within MATLAB to measure deformation velocity and visualize the results using R Studio. The findings reveal that the deformation velocity in Makkah City ranges from − 19.1 to + 19.1 mm/year, indicating areas of both subsidence and uplift. Notably, certain regions exhibit substantial subsidence, while others show upward movement or an uplift. This study demonstrates the effectiveness of the PS-InSAR technique in detecting surface deformation in Makkah City, offering a valuable and economical tool for creating risk maps and implementing disaster mitigation strategies. The results stress the importance of continuous monitoring in areas exhibiting deformation signals and provide crucial insights for urban planning and infrastructure development in Makkah City, helping to mitigate potential future hazards and enhance the city’s resilience to geological risks.
