The seismoelectric effect based on the data of measurements at the Mikhnevo Geophysical Observatory

Resumo

The results of analysis of synchronous instrumental observations of seismic oscillations and the intensity of the electric field at the Earth’s surface under the conditions of the mid-latitude Mikhnevo Geophysical Observatory of the Institute of Geosphere Dynamics, Russian Academy of Sciences (IGD RAS) are presented. The results provide evidence that the seismoelectric effect exists in the influence zone of the deep tectonic structure, which is clearly seen in the records when strong perturbations caused by other electric field sources do not exist (propagation of atmospheric fronts, thunderstorm events, formation of eddy structures in the atmosphere, etc.). For the first time, a quantitative relation between the amplitudes of the seismic and induced electric signals under specific conditions was obtained.
