The Beni Garfet area, located in the external Rif of northern Morocco, remains poorly documented in terms of its local structural and seismotectonic framework despite its position within an active tectonic setting. This study presents a preliminary local-scale assessment based on the integration of geomorphological observations, geological mapping, field investigations, and spatial analysis of seismicity. The objective is to investigate the relationship between surface structural features and the spatial distribution of seismic events in the vicinity of a mapped anticlinal structure. The results reveal a well-defined anticlinal morphology and a consistent spatial pattern of selected seismic events following an approximate northeast-southwest trend consistent with the orientation of the anticline axis. Geological cross-section analysis and field observations confirm the presence of a folded structural framework, while no clearly expressed surface tectonic structure was identified in the study area. This combination of observations suggests that the spatial distribution of seismicity may be influenced by a concealed or poorly expressed tectonic structure. Although the interpretation remains preliminary and is based on qualitative spatial analysis, the study provides a first integrated geomorphological and seismotectonic framework for the Beni Garfet area. The results further highlight the importance of considering potential subsurface structural controls in land-use planning, particularly in areas characterized by vulnerable building typologies.
