Abstract
Seismic activity is accompanied by emanation of soil gases into the atmosphere. These gases transfer positive and negative charged aerosols. Atmospheric convection of charged aerosols forms external electric current, which works as a source of perturbation in the atmosphere-ionosphere electric circuit. It is shown that DC electric field generated in the ionosphere by this current reaches up to 10Â mV/m, while the long-term vertical electric field disturbances near the Earth's surface do not exceed 100Â V/m. Such a limitation of the near-ground field is caused by the formation of potential barrier for charged particles at the Earth's surface in a process of their transport from soil to atmosphere. This paper presents the method for calculation of the electric field in the atmosphere and the ionosphere generated by given distribution of external electric current in the atmosphere.
