the required number of seismic sensors, the work was carried out according to the following scheme. One sensor was installed stationary in the middle of the dam’s crest. Other sensors (it may be one) perform sequential registration of microseisms at the i- th points of the dam’s crest. Next, the level of microseisms at each i -th point calculated relative to the stationary point.
