Abstract

The presented model for earthquakes is based on two fundamental principles: the hierarchical structure of seismic areas and the concept of self-organized criticality. The model reproduces the basic empirical properties of seismic processes: the frequency-energy scaling relation (the Gutenberg-Richter law), the generalized Omori law for temporal decay of aftershocks, the aftershock productivity law, the fractal distributions of hypocenters (epicenters) with power-law dependencies of the number of events on distances between hypocenters (epicenters), and, finally, the γ distribution for waiting times. In the model, the threshold energies depend on the block sizes and are distributed according to the Gauss law. After strong earthquakes they are redistributed at the decreasing average values. The change of threshold energies leads to the triggering of aftershock series.
