The ABEM Wadi VLF instrument that utilizes only a magnetic field component was used for the present study. This instrument measures the ratio of the vertical component of the magnetic field (H z) which depends on the subsurface conductor and the horizontal component (H x) of the primary magnetic field, which depends mostly on the VLF …

The VLF data were collected using ABEM Wadi instrument. The data were interpreted using KHFFILT software. The results of the study showed the presence of fracture zones and are prominently oriented in the NE-SW and NW-SE direction. The results also showed that most of the fracture zones were located at a depth range of 0 to 60m within the
