Annotation
Results of investigation of geoacoustic emission, which has been carried out since 1999 in Kamchatka, are presented. The particularity of experiments is application of broadband piezo-ceramic hydrophones installed near the bottom of natural and artificial reservoirs for registration of emission. Application of the receivers of such type allowed us to expand frequency range of registration from 0.1 Hz to 11 kHz. During the investigations the relation between activation of deformation processes in the near surface sedimentary rocks and high-frequency anomalies in geoacoustic signals was identified. It is observed the most vividly during final stage of earthquake preparation.
