This study presents an integrated, multi-scale characterization of fault damage zones along the northwestern Red Sea margin near Quseir area, Egypt, aiming to elucidate the complex structural architecture and scaling relationships that govern strain distribution and fluid flow in extensional tectonic settings. Despite their critical role in rift systems, fault damage zones remain insufficiently characterized in terms of their geometric variability, scaling attributes, and host-rock interactions along Red Sea margin. Here, we combine remote sensing analysis, detailed field-based structural mapping, and microstructural investigation to constrain the architecture and evolution of normal fault arrays and their associated damage zones.

Lineament analysis from multiple satellite datasets, digital elevation models, and field surveys enabled comprehensive structural mapping of basement and sedimentary faults, relay structures,
