<p>This study employs a geospatial technology-based approach to generate and analyze an updated database of tectonic lineaments for the Tetouan-Ras Mazari region in the northwestern Rif Belt of Morocco. For this purpose, eight shaded relief images were produced from the Shuttle Radar Topography Mission (SRTM DEM) data, which serve as a basis for extracting lineaments. Lineaments were extracted from each of the eight images. These extracted lineaments were compiled to create a final map of the study area, which was analyzed using ArcGIS^® and Rockworks^® software. To validate the results, we incorporated various data sources, including structural, lithological, and slope factors, as well as high-resolution field data imagery. Additionally, comprehensive fieldwork was conducted to corroborate and compare the findings with previous structural studies in the area. The study identified 488 lineaments, with a cumulative length of approximately 1729.14 km. The lineament density ranges from 0 to 3.32 km/km². The predominant orientations of lineament sets are E–W and NE–SW, closely matching regional fault systems. These lineaments exhibit substantial similarity in concentration and orientation with the regional fault systems. Lineaments are primarily associated with major faults, demonstrating higher density in the southern and northern parts of the study area compared to the western and eastern regions, indicating an elevated degree of rock fracturing and shearing. The increased lineament density in these areas enhances their susceptibility to hazards such as landslides and terrain instability. Consequently, these zones are not recommended for the construction of highways and dams. However, areas with high lineament density can also offer opportunities, such as the potential for water exploration. Furthermore, the results obtained from this research highlight the importance of extracting lineaments using multiple azimuth angles, as they provide more accurate information than using a single azimuth angle.</p>
