| Zusammenfassung |
| The paper presents the results of investigations of deformation processes in
the near-surface sedimentary rocks, which have been carried out in a
seismically active region of the Kamchatka peninsula since 2007. The
peculiarity of the experiments on registration of geodeformations is the
application of a laser strainmeter–interferometer constructed according to
the Michelson interferometer scheme. Besides rock deformations, geoacoustic
emission in the frequency range from several hertz to the first tens of
kilohertz is under investigation. Piezoceramic hydrophones installed in
artificial water reservoirs are applied. It is shown that periods of primary
rock compression and tension with a duration of up to several months are
distinguished in the geodeformation process at the observation site. During
the direction change in the deformations, when the geodeformation process
rate grows, an increase in geoacoustic radiation is observed. |
