摘要：

The earlier proposed method for inversion of the observed changes in the magnetotelluric apparent resistivity ρa into the relative changes in the resistivity of the elements of a well-studied geoelectric structure is tested on a 2D model representing one of the geodynamic research areas of Kamchatka. The possibilities are demonstrated for choosing the most effective observation conditions of the study, and for the determination of the source of the observed variations in γa. It is concluded that, if a number of conditions are met, it is possible to estimate the amplitude of relative changes in the electrical resistivity of rocks with sufficient accuracy for monitoring these changes with the aforementioned changes used as a prognostic parameter.
