The aim of this study is to improve the structural map of Douala-Kribi basin. For this purpose, computer tools are used to make qualitative and quantitative analyses to interpret the gravity data. The findings provided several maps which are: the Bouguer gravity anomalies, residual, horizontal gradient, analytical signal, tilt angle, variation of depth, and multi-scale analysis gravity anomalies maps. A thorough examination of these maps highlights lineaments interpreted as faults, and intrusive bodies in the study area. The multi-scale analysis helped to portray the deep faults and therefore construct the structural map of the Douala-Kribi basin. The application of the Euler deconvolution method and variation of the maxima solutions of horizontal gradient upward continuation (HGup) have resulted in the depth of the structures and the intrusive bodies. The faults identified in the Douala-Kribi basin seem to be induced by tectonic movements in addition to the uprise of intrusion. The Euler solutions and tilt angle depths are included in those of the residual field while those from the analytical signal partly overlap those from the residual field and tilt angle. Then, the Euler solutions maps, and the maxima solutions contribute to highlighting the trust interval depth which is the compatibility depth.
