Abstract
On 17 August 2009 Sayano-Shushenskaya Hydroelectric Power Station suffered a catastrophic accident. In the “Report of technical investigation of the accident cause” as the main cause of the accident it was called “repeated appearance of additional loads of variable nature on the hydroturbine unit”. But what kind of loads, what is their source? The research presents the method, which allows to control by seismic records not only work of various sources, but also to determine parameters of their dynamic forces to the structure.
