The present work deals with the integration of remote sensing data with surface geology and gravity survey to improve the structural knowledge of the Tarhunah area, northwest Libya. Geological information and remote sensing data provided information about the surface structure. The gravity survey was conducted to explore the subsurface structure. The results revealed a basin trends in the NE direction with width varying from 39 to 48 km. A 2D schematic model shown the basin is gradually deeper toward the southwest direction. Faults extracted from horizontal gradient, tilt derivative, and Euler Deconvolution shown a depth ranges from 2.5-7.5 km. The integration and interpretation of the results indicates that the study area was affected by three main movements. And the volcanic activity was related to the tectonic activity of Jabal Uplift.
