INVESTIGATION OF SEISMICITY DYNAMICS IN THE BAIKAL REGION

Abstract

For the first time, the methods of fractal theory were applied to the study of seismicity dynamics of the Baikal region and its three areas. Estimates of the Hausdorff dimensionality (D) show self-similarity of the seismic process in 1967–2002 with a 10% significance level. The most prominent Hurst index (H) and D variations correspond with the aftershock series of strong earthquakes, while regions of high H and D values are congruent with the concentration zones of earthquake groups, suggesting a high influence of shock clusters on the regional seismicity.
