Abstract: | Research has shown that the creation of the Bratsk water reservoir considerably changed the seismic conditions in this area of the Siberian Platform. Seismic records revealed a significant increase in the energy classes of earthquakes with epicenters in the north of the reservoir, in trap intrusion zone. The change in engineering-geologic conditions and frequent seismic events affected the rate of development of gravitational deformations on the shore slopes. |
