ABSTRACT

Investigations with the use of IR satellite maps were conducted on parts of the Baikal Rift Zone (BRZ, East Siberia, Russia), the Tarim platform (north-west China), the San Andreas transformfault, the Great Basin (western part of the USA), the Afar depression (north-east Africa) and the Rhine graben (west Germany). It has been determined that the localized IR-radiation correlates with geophysical parameters, locations of hot water springs and geochemical anomalies. High intensity of the outgoing ground-based IR flow, which is registered by the ASs, is spatially localized on the surface of seismoactive faults and tectogenic slopes, which are formed in the zone of dynamic influence of the fault ZDIF. The outgoing surface IR flow depends on the state of the active ground layer due to the drift of thermodynamic temperature for the area observed from ASs. The identified value of the flow, which is independent of it, represent quasi-steady IR flow – Iconst. Quasi-steady IR flows of faults are identified by minima of seasonal increments in the IR domain, make 85.46 ÷ 112.24 MW/m2.ster.μm and correspond to their proper surface IR radiation. Mathematical investigations allow one to identify low-frequency oscillations having the length of the geometric wave equal to 94.23 km, the amplitude being about 2.2 MW/m2.ster.μm. The complete power of the outgoing surface flow of IR-radiation corresponds to the power of its low-frequency component. The valuable powers of the flow for the highfrequency domain are bound up with the geometric wavelength being not less than 20 km. The energetic contribution of the elements having the wavelength
