This article is devoted to describing the theory, technique, and first experimental results of a control source electromagnetic (CSEM) study of the Earth’s crust and ionosphere with the use of two mutually orthogonal industrial transmission lines 1
Borehole radiophysical properties are briefly described. Borehole investigation of lithosphere acoustic-electromagnetic radiation was carried out in a seismically active region. Four main types of anomalies of acoustic-electromagnetic radiation were
