Abstract 

Our study quantifies co-seismic deformation in the Ouarzazate Province, Morocco, caused by the 2023 Mw 6.8 High Atlas earthquake using Interferometric Synthetic Aperture Radar (InSAR) technology. We identified significant ground displacement, with uplift reaching up to 5 cm in Northwest areas of the province and subsidence down to -3 cm in The Ouarzazate Basin. The displacement patterns correlate strongly with existing fault lines, particularly the South Atlas Fault (SAF) and its branches. These findings highlight the region's seismic vulnerability and emphasize the need for further research to mitigate potential seismic hazards.
