Quasi-static electric fields phenomena in the ionosphere associated with pre- and post earthquake effects
International audience To prove a direct relationship between the quasi-static electric field disturbances and seismic activity is a difficult, but actual task of the modern ionosphere physics. This paper presents new results on the processing and analysis of the quasi-static electric field in the u...
