Abstract
Lithosphere-atmospheric-ionospheric relations have been investigated at the example of the perturbations propagation from the lithosphere to ionosphere during underground nuclear explosions at the Semipalatinsk test site and two earthquakes (Mb = 3.5 and Mb = 3.6) near Almaty. Simultaneously, seven days prior to the earthquake the abnormal effects in variations of intensity of a gamma-ray flux, temperatures, acoustic impulses and the Doppler frequency shift of ionospheric signal are registered by a complex of the measuring equipment installed in the mountain area. A retrospective analysis of the recordings of the Doppler frequency shift of ionospheric signal variations during the UNEs at the Semipalatinsk test site detected disturbances in the DFS records 15–18 minutes after the explosion and the response of ionosphere to the acoustic wave. The anomalous effects recorded in ionosphere when UNE radioactive products penetrated the atmosphere and when gamma-ray flux increased prior to earthquake, apparently have a common mechanism for disturbances perturbation to ionosphere, namely, the ionization change of the atmospheric boundary layer leading to the total current change between the ionosphere and the Earth.
