Question of the probably application the electromagnetic control source method for the apparent resistivity monitoring is subject discussion. The measuring scheme, arrangement versions and practical diagrams is proposed. Decrease apparent resistivity before the earthquake (M = 7.4) from 840 to 84 Omm is fixed.
