One of the actual problems in quantitative seismology is the improvement of technologies of
remote observations of a mechanical stress field in Earth’s crust. One of the technologies of
such observations, whose efficiency in ground seismological observations is repeatedly confirmed
by practice, is the seismic monitoring widely applied nowadays for the operative control over
a condition of the natural and man-made complexes (geological faults, mines, dams, mined
oil and gas deposits, etc.). Among various versions of seismic monitoring technologies, it is
possible to separate the active monitoring by a stream of weak probing sound signals which are
energetically comparable with the natural background. We consider features of such a monitoring
which are related to fluctuations of the parameters of probing sound signals in the mode of their
accumulation and the subsequent processing.
