It is shown that the main source of energy for their existence and development, especially the seismic regime are thermal conditions of the subsurface shape and spatial position of irregularities in the body of the earth and its rotation-pulsation mode as a planet.seismic regimedepth of Earthглубинные разломысейсмический режимземные недра
