Abstract

The paper gives a summary of geophysical aspects of man-made electromagnetic noise in the Earth as follows:- EM distortion effects of man-made constructions below and over the Earth's surface defined as 'passive-noise', - field observation of EM disturbances due to 'active' man-made sources, - EM source mechanism of some important active sources from a geophysical point of view, - efforts in order to improve the signal-to noise ratio by instrumental, methodological and dataprocessing ways, - application of man-made EM noise for geophysical prospecting. The paper is based on world-wide EM noise survey studies published mainly in geophysical journals.
