Highlights

– The efficiency of sounding the lithosphere by an active source is shown

– A two-layer model of the Earth's crust is a good approximation for the conductivity in the region of Varzuga

Abstract. Experimental studies of signals from a controlled source in the middle zone under various geophysical conditions have been performed. In the experiment, five field electromagnetic components were measured in the range 0.3–95 Hz. Based on these observations, the effective conductivity of the underlying surface was calculated and an interpretation of the results was given.

Keywords: ELF, radio wave propagation, impedance, electromagnetic field, conductivity
