Abstract
In this work, we used seismic refraction and magnetic methods to find the extension of a known subsurface fault and delineate for the existence of many others. Combination of both seismic refraction and magnetic method give a better subsurface view, where both seismic and magnetic methods can detect fault locations; however, fault thrown and subsurface layering will be better detected by seismic method, while magnetic method will provide a better lateral view of the faulting system in the study area. Seismic refraction shows that at least two fault plans exist in the subsurface; magnetic results supported seismic results and suggested the existence of several small fault plans in the study area.
