Application of vibro-seismic technology to the study of seismic risk


OBJECTIVE: The development of new active seismic monitoring technology to study seismic-prone zones on the basis of the new type of vibrator.

IMPORTANCE: At present, the problem of predicting time, intensity and estimation of damage caused by a feasible earthquake, is gaining significant importance. The current techniques aimed at studying seismic- prone zones and their interior tectonics cannot answer these questions with proper accuracy. The new type of vibrator based on the hydroresonance principle, which have been developed at the Siberean Department of the Russian Academy of Sciences, gives the new approach to seismic-prone zone control, using active vibro-seismic monitoring. The vibrator has power amplitude of about 200 tons, frequency range of 0.5 - 15 Hz and obtains seismograms at the distance of up to 300 km.

THE LINE OF RESEARCH: Computational experiments show that dynamic features such as polarization, damping, frequency etc. serve as indicators of vibrations in reological characteristics of the medium. The project is aimed at:
