About this document

VLF-EM Method for Geological Analysis by Shofi Hawan is a document available to read on EtoBox.

This document discusses parameters used in Very Low Frequency Electromagnetic (VLF-EM) studies, including: 1) Tipper, the ratio of vertical to horizontal magnetic fields, is used as a diagnostic indicator, with anomalies indicating subsurface conductors. 2) Tilt angle and ellipticity express the polarization of VLF fields and are related to the real and imaginary components of tipper. 3) Apparent resistivity and phase angle between electric and magnetic fields provide information about subsurface resis
