SOLAR ACTIVITY AND SEISMICITY OF THE EARTH IN THE NORTHERN TIEN - SHAN

Work is devoted to the discussion of the experimentally observedconformity between the intensity of cosmic rays and variationsin solar activity and characteristics of seismicity in the Northern Tien Shan. Explanation of this fact is based on the analysis of the results of theoretical studies on the impact on the terrestrial rocks of the penetrating component of cosmic rays ?the muons. Under such exposure, microcracks can be formedin the rocks which is accompanied by the appearance of acoustic waves. If this reaction of muons occurs with highly stressed seismically active medium, the energy seismic waves emanates can increase by more than 20 orders of magnitude.This may cause not only the generation of an acoustic wave but also, of a seismic wave associated with an earthquake.
