PRESENCE OF TECHNOGENIC STRUCTURES IN NATURAL ELECTRICAL FIELD

Abstract

A methodology of self-potential that allows to confidently detect sites of underground water movements, including the ones near the foci of underground nuclear explosions (UNE), based on the contrast and intensity of self-potential features, has been developed. The main features of distribution are the decrease of self-potential values at the sites of the source and narrowing of the underground water flows and increase of self-potential values at the sites of slowness and widening of these flows. At the UNE sites the nature of self-potential is complicated – linearly stretched in different directions, often – mosaic one. In a number of cases ring structures co-concentric with the UNEs foci have been noted.
