Geomorphology of the Sinú fold belt in the southwestern sector of the Colombian Caribbean

This study analyzes the geomorphology of the southwestern continental margin of the Colombian Caribbean, with emphasis on the Sinú Fold Belt, a key region for marine resource research and exploration. The research employs bathymetric data and 2D seismic profiles to characterize geomorphological features controlled by tectonic, sedimentary, and fluid-emission processes. Structural ridges and intraslope basins associated with tectonic activity, submarine valleys and scars linked to sedimentary transport, and mud volcanoes were identified as evidence of fluid flow. In addition, the mass transport complexes on the continental slope imply slope instability processes that dominated this sector of the Colombian Caribbean and pose potential geohazards. The resulting geomorphological map (scale [Formula: see text]) integrates morphostructural and morphosedimentary features. Mapping mud volcanoes, over [Formula: see text], this study identifies slope instability as the main geohazard, establishing a solid basis for regional risk management.
