Seismic cycles, size of the largest events, and the avalanche size distribution in a model of seismicity.

摘要: We address several questions on the behavior of a numerical model recently introduced to study seismic phenomena, which includes relaxation in plates as key ingredient. First, we make an analysis scaling largest events with system size and show that, when parameters are appropriately interpreted, typical scale size, without necessity tune any parameter. Second, that temporal activity is inherently nonstationary obtain from here justification support for concept ``seismic cycle'' evolution activity. Finally, ask reasons display realistic value decaying exponent $b$ Gutenberg-Richter law avalanche distribution. explain why induces systematic increase its $b\ensuremath{\simeq}0.4$ observed absence relaxation. However, have not been able justify actual robustness displaying consistent around experimentally $b\ensuremath{\simeq}1$.
