Abstract

The method of\/ active vibroseismic monitoring being developed recently suggests geological medium probing by seismic waves from artificial controlled sources. Here the changes happening in the stress-deformed state of the medium and its rheologic characteristics are determined by changes in the information parameters of seismograms, i.e., by changes in the amplitudes and times of income of various waves, their spectral and polarization characteristics. Facilities available nowadays, such as powerful low-frequency vibrators and digital distributed seismic signal detection systems, make it possible to perform vibroseismic monitoring of large seismic dangerous zones of 10,000 to 40,000 square kilometers.
