Connection of the Earth crust stress variation to the full solar eclipse and the propagation of magnetic storms
The infl uence of the solar eclipse and magnetic stroms on the sesmic activity intensifi cation was considered for several seismic zones in Russia for the period of 2004-2008. It is determined that the infl uence of magnetic storms on the seismicity does not always correlate directly with the magnetic storm intensity. The same magnetic storm may intensify in some regions and may not intensify it in the other regions. The full solar eclipse and magnetic storms intensify seismicity only in case the geological environment occurs in the stress state (the trigger effect). For all considered regions (except the northernmost regions, i.e., Yakutia and the Kola Peninsula), the seismicity intensifi cation is registered in less than 40% cases. The infl uence of the full solar eclipse and magnetic storms on the amplitude-frequence characteristics of the microseismic noise is proved.
