Abstract
Very Low Frequency (EM) investigations were carried out in the Osmania University Campus, Hyderabad to delineate structural configuration and trace subsurface fracture zones at depth could represent groundwater potential zones. A qualitative interpretation of VLF-EM data along the AA1 to SS1 traverses is based on the crossover point, amplitudes of filtered real and imaginary components are appears as positive peaks in the Fraser filter real curve. This region constitutes anomalous zone which can be attributed the presence of vertical conductive or lateral contacts of different conductivity beneath the surface. Qualitative maps tilt derivative and analytical signal trends lows and highs are mapped which are reflecting similar trends of fractures, which are indicating structural configuration, conductive subsurface conductors at depth representing the groundwater potential zones.
