Seismo-acoustic Emission in Near-zone of Powerful Vibrator

The results of the full-scale experiment on the study of vibrations influence on seismo-acoustic emission in near-zone of powerful 40-ton vibrator are presented. It is shown that after vibration sessions lasting a few tens of minutes the gradual increase of energy of microseisms takes place. After ending of the vibrations energy of microseisms begins to decrease. Data processing using the algorithm of seismic emission tomography justifies the endogenous nature of microseisms initiated by powerful vibrations.
