| Abstract: | Investigations aimed at revealing traces of recent tectonic activity in geological fault zones were carried out in 2006 in the territory of southern Yakutia and the Amur region in connection with works on detailed seismic zoning of the route of the East Siberia-Pacific Ocean oil pipeline. In addition to geological-geomorphological and geophysical studies, the complex investigations included paleoseismogeological studies and were accompanied by the driving of mine workings through topographic forms that could be associated with zones of active tectonic disturbances. This approach made it possible to substantially refine the available information on seismotectonics and the potential seismic hazard of the region. |
