Abstract
The subsurface fault structure near Al Khoud area of Muscat city, Sultante of Oman, was investigated using very low frequency electromagnetic (VLF-EM) method at two different transmitter frequencies namely 15.1 and 16.0 kHz. The measured in-phase and out-of-phase components were processed and interpreted in order to determine the depth to the top and width of the fault by Kharous-Hjelt filtering and the amplitude of analytical signal approach. In addition, the principal profiles from the contour maps of in-phase and out-of-phase components when processed and interpreted yield similar results for depth and width of the fault structure. The over all results suggest that the nature of fault structure is dipping as it lies at a wide range of depth from different profiles. The results are presented highlighting the merits of the methods.
