Abstract
The character of seismic activity in the northern Pribaikalye is considered in connection with the block structure of the crust. It is supposed that presence of structural elements of different scale levels and density heterogeneities in the crust gives ground for earthquake clustering and prevents large (M > 6.0) seismic events. The representativeness of clusters and the character of stress discharge in sources change gradually as you move away from the conditional axis of the rift zone to the S-E demonstrating a weak influence of rift processes in the area of the Ikat Range.
