Stressed state of the medium in the lithosphere of the Baikal rift zone based on the data of seismic moments of large earthquakes

The possibility of a tsunami on Lake Baikal

“…earthquake magnitude increases[6]: for exam ple, if at a shock of magnitude M = 5 and a displace ment along the fault D ≈ 0.04 m, the length and width of a focus of crustal earthquake are equal to L ≈ 8.3 km and W ≈ 3.6 km, respectively, then at magnitude M = 7 -L ≈ 62 km, W ≈ 24 km, and D ≈ 1.2 m…”

“…Note: M and M 0 are the earthquake magnitude and seismic moment, L and W are the length and depth of the earthquake focus; D is the displacement along the fault[6].…”

“…The range of magnitudes was selected in this range, so that the min imum magnitude of an earthquake when a surface fault forms, as well as a lithospheric block surface dis places quickly, and disturbance forms on the reservoir surface, was equal to M L ≈ 5 [5]. The amplitude of block displacements during earthquakes of this mag nitude is approximately 0.04 m [6], and due to the small compressibility of water, the amplitude of distur bance on the water reservoir surface would be about the same. This value is close to the lower limit of the range of wave height in the region of tsunami occur rence (0.01-5 m).…”
