Abstract
An electrical resistivity and electromagnetic emission survey was carried out involving the use of
vertical electrical soundings (VES) and natural pulse electromagnetic field of the earth (NPEMFE).
The use of this new methodology managed to detect the fracture flow system rupture zones in the
underground, also answered the questions about the deferent subsurface water bodies. The present
study focuses on Marsaba-Feshcha sub-basin in the northeast of the Dead Sea. Due to the
scarcity of boreholes in the study area, several geophysical methods were implanted. The combination
of these two methods (VES and NPEMFE) with the field observations and East-West transversal
faults with the coordination (624437/242888) was determined, cutting through the anticlines
with their mainly impervious cores with fracture length of >400 m. These transversal faults
saddle inside Nabi Musa syncline (Boqea syncline), leading to a hydraulic connection between the
Lower and the Upper Aquifer. Due to the identified transversal fault, the water of the Upper and
Lower Aquifer mixed and emerged as springs at Ein Feshcha group.
