Abstract
Results of retrospective analysis of in situ observations in the dam foundation and adjacent bank rocks of the Sayano-Shushenskaya hydroelectric power station (SSHPS) during the nucleation and energy release of the Altai earthquake of September 27, 2003, are presented. A group of most reliable precursors of this earthquake is identified in measured parameters monitoring the state of the facility and surrounding bedrock. The correlation is examined between the precursor occurrence time and the energy of the earthquakes recorded in the regional catalog in 1990–2005, in the period of the normal SSHPS operation.
