Engineering Physics Annotation << Back ECHO OF THE CAVES F.F. MENDE, A.S. DUBROVIN The conducted experimental investigations showed that mechanical stresses or destruction of conductors and dielectrics lead to the appearance of unitary charge in such models. Friction between the separate threads or the dielectric layers they lead to the same effect. With the earthquakes, which are the consequence of the accumulation of stresses in the layers of species and their subsequent break or relative shift, also must appear the electric potentials, which present the unitary of charge, whose fi elds can without diffi culty penetrate through the rocks, falling into the atmosphere and into the ionosphere. The shift processes, which associate earthquakes, which lead to the friction between the shifting layers, also can lead to the appearance of electrical pour on. These fi elds can ionize the atmosphere and the ionosphere, causing its glow. If tension pour on, that appear with such processes, exceeds breakdown stress for the atmosphere, then lightning can appear. The seismic waves, which are extended during the earthquakes, also lead to the periodic mechanical deformations of the layers of species. These deformations also can cause the appearance of electrical pour on out of the zone of the propagation of such waves. Key words: earthquake, atmosphere, ionosphere, lightning, charge, potential.
