MICROSEISMICITY AND INTENSITY OF RELAXATION PROCESSES IN THE EARTH'S CRUST

Abstract

In this paper, we present the experimental data on the influence of background amplitude A on intensity N of relaxation processes in the earth’s crust. We have established that the intensity of relaxation processes correlates well with the amplitude of background microoscillations. The degree of correlation depends on spectral components of background microoscillations. The best correlation between N and A is observed in frequency range 0.5–40 Hz in region with high tectonic activity (the coefficient of linear correlation is K = 0.73 at the level of significance r = 0.995) and frequency range 0.1–10 Hz in the crustal region characterized by low tectonic activity (K = 0.75; r = 0.995).
