AB: Recent theoretical and experimental studies within the frame of Lithosphere-Atmosphere-Ionosphere Coupling model (LAIC) permitted to generalize a common conception of different kinds of specific variations of geochemical, atmospheric, electromagnetic and ionospheric parameters observed before strong earthquakes. The long history of this conception (starting in 1990) and the several existing updates are mostly connected with its interdisciplinary character. LAIC is based on two simple but fundamental facts: 1) specific variations (usually increase) of radon emanation have place for every earthquake; 2) increased emanation of radon from the Earth's crust in the vicinity of active tectonic faults before an earthquake take place within the earthquake preparation area estimated by Dobrovolsky. Air ionization by radon takes place over the large territories and has a strong effect on the following processes in the atmospheric boundary layer: (1)formation of the large ion clusters due to water molecules attachment to ions; (2) latent heat release; (3) changing of boundary layer electric conductivity; (3) upward convective flux, generation of anomalous electric field; (4) air temperature increase and drop of relative humidity and (5) specific shape clouds formation. Variations of atmospheric electricity stimulated by ionization process induce variations in the ionosphere trough the global electric circuit. The simultaneous co-existence of several processes manifesting this coupling explains the variety of observed phenomena and enhances the reliability of detecting the future seismogenic signals. Interactive model improvement through data fusion using the data of satellite and ground based monitoring for the major recent earthquakes revealed new aspects of energy conversion from chemical reactions up to thermodynamics and electrodynamics.
