3 zones of earthquake sources around SSHGES caused by three faults that run parallel to each other along the Western Sayan. These zones are called Sayano-Tuva (130 km from the Sayano, figure 1), Bolsheporozhskaya (60 km from the Sayano-Shushenskaya HPP, figure 2) and Borusskaya (10 km from the Sayano-Shushenskaya HPP, figure 3). The most terrible is to SSHGES Borussky hearth, as the closest, it was not long ago earthquake. Many earthquakes began to occur in 2007 on the first fault, the most distant of the Sayano-Shushenskaya HPP. www.tuvaonline.ru/2008/11/03/2000_earthquakes.html
They were mostly in the Bai-Taiga and Barun-Khemchik areas directly adjacent to the reservoir SSHGES. That is the impact of the reservoir on the face.
The worst thing is that yesterday's earthquake directly on the fault and the second outbreak, which means it is activated and the approximation of the active earthquake zones closer to the dam, on the order of the third and most dangerous fault under SSHGES. Sequence on the face.
