Abstract
Generation of the electrotelluric field (ETF) by geodynamic processes in the earth crust is considered. It is supposed that the ETF arises due to the electrokinetic effect caused by deformation of the earth crust. Based on this model, a new technique for ETF measurement is proposed. The possibility to use electrical fields caused by the tidal waves for calibration of the measurements is also considered. It is shown that the tidal variations of pore pressure and electrical fields essentially depend on medium permeability, porosity, and viscosity of a liquid. It is shown that by using observations of the vertical electrical field it is possible in principle to determine the mechanical properties of deformable medium. All effects reach a maximum near the earth surface and can be measured.
