Karazin popup.description2 An object of study is the tropospheric and ionospheric perturbations associated with seismic events, and their interaction. The work aim is a study of influences of seismic events on tropospheric and ionospheric parameters at different distances from the seismic region. The basic results. 1. In a unique experiment in the salt mine at a depth of 260 m it was spontaneous electromagnetic emission in the frequency range 2.5 - 50 kHz registered, which generated exclusively lithosphere sources, indicating a permanent presence of the lithospheric component in the surface electromagnetic noise. For the first time shown that the variation in VLF range in the seismically quiet region correlated with changes in global seismic activity. The mechanism of the phenomenon is suggested to be the nonlinear distant propagation of lithospheric seismic-acoustic signals from the hypocenter of the earthquake (EQ). 2. It was found that remote EQ with the energy E>1012 J. in the lower ionosphere cause several types of disturbances over a distance of about 10 Mm from the hypocenter; horizontal velocities these disturbances propagation are 0.5 - 100 km/c. 50 - 200% increase of electron density with the duration of about 10 - 20 minutes at altitude of 78 km was often observed. It may be explained by high energy electrons precipitation from the Earth's radiation belt, initiated by EQ through a complex chain of processes. 3. Using data of latitudinal variations of ionospheric total electron content in the area of the equatorial anomaly formation for it was shown that the impact of EQ on the ionosphere may be observed not only near, but at great distances from the epicenter (more than 6000 km). The physical study of the results is given. 4. Analysis of simultaneous variations from day to day in lithospheric, tropospheric, ionospheric and magnetospheric parameters indicates the presence of variations with periods of 3 - 6 days (including kvazi-synhronic), which often have no obvious connection to space weather and local powerful disturbances. Availability interaction layers of the Earth based on relatively weak in the energy sense mechanisms indicate the possibility of the generation and behavior of processes in the lithosphere, troposphere, ionosphere and magnetosphere as the single nonlinear open system. The results are important for developing the empirical and theoretical models of the ionosphere, modeling physical mechanisms of interaction between different layers of the atmosphere, estimation of ecological effect of natural and anthropogenic processes on condition of life and for the development and punning of radio systems of various purposes. The results will be used in the preparation of the Doctor of Science Thesis, in the preparation of Bachelor and Master Thesises, in lecture updating. Product Description popup.authors Гоков О.
