Abstract

The effect of vibrations (storm microseisms) in Lake Baikal on seismicity in its shore zone is investigated by comparing the number of earthquakes that occur in winter in the absence of waves and vibration to that during the time of strongest storms. Observations over ten recent years show that the number of small and medium earthquakes (6 K 13) in "quiet" time is nearly twice as high as that during storms, which indicates the influence of storm vibrations on the seismicity. The observed vibrations have been analyzed in terms of their spectra, attenuation, amplitude, and radius of influence.
