The article presents modern structural-tectonic plan and tectonic-dynamic model of the zone of interaction of the most seismicity active northeastern part of the Baikal rift zone (BRZ) and the adjoint system seismogenic structures of the Aldan-Stanovoy block in southern Yakutia, where is marked a series of seismic disasters with magnitude M ≥ 6. The patterns of structure formation and kinematic types of adjoint active faults, which form structural blocks, where accumulate considerable tectonic stress are discussed. The interaction between large tectonic blocks causes a sudden release of stresses, which results in catastrophic earthquakes (M ≥ 6.0) with focal mechanisms of definite kinematic type.
