Features of Seismic Activation of the Middle Baikal Region, 2008-2011

摘要

Scenarios for developing focal zones of strong (M_w =5.3) earthquakes that occurred in the Middle Baikal region in 2008 and 2011 are considered. The new (submeridional and sublatitudinal) lines of destruction of the Earth's crust in the water area of the lake are recorded. The facts of seismoactive structures forming in the surrounding mountains (to the southeast) under typical rift conditions of movements are established, which indicates that the basin of Lake Baikal is expanding and growing due to active capturing and processing of its mountain surroundings.
