Abstract

Electromagnetic methods to infer subsurface resistivity structure particularly in volcanic and hydrothermal regions are considered highly effective to apply. Time domain electromagnetic (TDEM) method as one of them, is a robust method utilizing controlled-galvanic source which has higher ability to penetrate deeper structure. This paper tries to elaborate the theoretical formulation of TDEM with a long-grounded current wire for a layered-earth problem, the mathematical inversion algorithm to find the suitable model for interpretation as well as its sensitivity analysis, and the application to synthetic and real measured data.
