AB: Based on the results of the satellite Dynamic Explorer-2 measurements it is established that the earth's crust large geological structure peculiarities influence on the ionosphere parameters outside of Auroral zone. It is characterized by occurrence in the ionosphere of areas of the sharp increasing of the low-frequency electric field in the range 1-500 kHz and the spectral density of the plasma fluctuations of the decameter scale; in these zones of the epithermal electrons penetrations are observed also. The specified effects do not depend on the seismic activity, local time, seasons and the level of the geomagnetic activity. Some hypotheses about the possible mechanisms of the lithosphere-ionosphere coupling, which are responsible for the found out effects, are stated.
