Abstract

The model study of amplitude-spectral variations of low-frequency signals propagating in the Earth-ionosphere waveguide when seismic disturbances occur on the upper wall of waveguide - in the lower ionosphere have been carried out. The possible characteristics of seismic disturbances in the lower ionosphere causing the observed amplitude variations of signals are considered on results of the comparison with experimental data of observations of VLF- signals. The results of calculations of the dependence of spectra of low-frequency signals on the parameters of the Earthionosphere waveguide propagating along paths with disturbances in the ionosphere show that the increases in the signal amplitude registered in the experiment during periods of strong seismic events can be explained by the increase in the steepness of the electron profile and/or the increase in the height of waveguide.
