Abstract
The effect of vibrations (storm microseisms) in Lake Baikal on seismicity i n its shore zone is investigated by comparing the number of earthquakes tha t 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 <less than or equal to> 13) i n "quiet" time is nearly twice as high as that during storms, which indicat es the influence of storm vibrations on the seismicity. The observed vibrat ions have been analyzed in terms of their spectra, attenuation, amplitude, and radius of influence.
