Abstract

In this chapter, the telluric current method is introduced. It is the earliest geophysical method that was applied to the Earth’s natural electromagnetic field. The topics included for discussion in this topic are: (i) the relative ellipse method for nearly elliptic polarisation of the telluric current field; (ii) polygon (triangle, quadrilateral, pentagon, hexagon etc.) method for nonelliptic polarisation; (iii) the amplitude ratio method for linear or nearly linear polarization; (iv) the absolute ellipse method for nearly elliptically polarized field; (v) demonstrations of the application of analytical continuation for interpretation of telluric field data; (vi) one set of results obtained by analytical solution of boundary value problems using complex variables are; (vii) discussion of a few basic points on nonpolarisable electrodes; and (viii) an experimental set up of a physical model in a model tank in which any kind of 3D subsurface models can be simulated and the nature of the distribution of absolute ellipses can be studied. A few case histories are presented and qualitative-to-semi-quantitative interpretation procedures are outlined.
