In the article the results of studies of stress-strained state of the crust in Chatkal`s mountain zone of west Tan-Shan are shown. In the first approximation the main and paleo-stresses for separate area of the region`s are estimated. For analysis of the stresses the methods of mathematical modeling and tectonophysical methods of stresses fields reconstructions and method of recovering of stresses by earthquakes mechanisms are used.

Purpose. The aim of the work is to present and to analyze the results of physical modeling and field studies of processes of formation, evolution and modern geodynamic and seismotectonic activity of subvertical shear zones (SVShZ), in particular of faulting kinematics. Methods. Physical modeling was conducted on the special modeling machine for break dip angle 75, 60 and 45. As a plastic-viscous modeling materials for this were used a special paste which are based on clay. Field researches included geoacoustic emission, PIEMPZ, extenzometric, tiltmetric and seismological methods.
