Detailed geologic and geophysical investigations of zones of active faults, and seismic hazard of the South Yakutia region
Active faults play a key role in morphostructure formation and seismic control within the Olekma-Stanovoy seismic zone. Detailed geologic-structural and morphotectonic investigations carried out in the fault zones made it possible to assess kinematics of active faults and the degree of their activity in the Holocene (the last 10,000 years). Ancient faults are present among them, for example, the Stanovoy suture of Proterozoic age. Most faults are young - Late Mesozoic and Cenozoic. The investigations were paleoseismogeologically oriented and were accompanied with mine workings driving through the land forms, which can be associated with zones of active tectonic dislocations; the latter have been geophysically prestudied. The practised approach made it possible to substantially specify the available data on the seismotectonics and potential seismic hazard of the region.
