Keywords: geoelectric structure, fault zones, monitoring of electromagnetic parameters, technological developments, seismicity distribution, geodynamic interpretation, Tien Shan
Аnnotation: The 45-year experience of the Research Station of the Russian Academy of Sciences in Bishkek in carrying out magnetotelluric (MTS) and magnetic-variation (MVS) soundings in the territory of the Tien Shan region is summarized. The features of the hardware and methodological support of field electromagnetic measurements in the mountainous conditions of the Tien Shan are discussed. The main results obtained on the basis of the developed methods of analysis and interpretation of MTS-MVS data, adapted to the complex geoelectric conditions of the Tien Shan, are considered. These results outline: 1) studying the deep structure of the Tien Shan lithosphere; 2) studying the nature of the relationship between the spatial distribution of seismicity and the structural pattern of the geoelectric heterogeneity of the geological environment; 3) monitoring the electromagnetic parameters of the lithosphere to study the dynamics of the stress-strain state of the Tien Shan geomedia;4) complex geological-and-geophysical analysis of the geoelectric structure and geodynamics of the Tien Shan.
