ABSTRACT
Results are presented of deformation monitoring of tectonic discontinuities in the zone of the Main Sayanskiy Fault, a seismogenic discontinuity located at the South-western boundary of the Baikal Rift System. Measurements that were held for two years and a half, had shown that typical episodes of fault slippage last from several seconds to several days, showing phases of velocity increase, slowdown and relative rest.
The spectrum of sliding episodes observed at one and the same discontinuity can be rather wide. Analysis of the results allows to suggest that depending on stress-strain conditions and factors that initiate fault slippages, the integral deformation regime is governed by different local segments of the fault interface, which have different rheological properties.
