The article describes the methods of observation and data interpretation of electromagnetic methods with a controlled source for seismically active regions of Siberia. The approach proposed by the laboratory of electromagnetic Fields of IPGG SB RAS is being developed to estimate the variations of geoelectric parameters by determining them by solving an inverse problem. An analysis the results of the interpretation of VES monitoring data using the integral electrical conductivity parameter presented for the site in the Selenginskaya depression of the Baikal rift zone. For the territory of Gorny Altai, a measurement technique demonstrated with several modifications of the TEM method for determining variations of electrical resistivity and anisotropy coefficient in the aftershock period of the 2003 Chuya earthquake. Attracting the electrical anisotropy coefficient expands the informativeness of the study, as it allows monitoring variations associated with changes in the seismic regime and allows assess the degree of activity of fault zones.
