摘要

Landforms and earthquakes appear to be extremely complex; yet, there is order in the complexity, Both satisfy fractal statistics in a variety of ways, A basic question is whether the fractal behavior is due to scale invariance or is the signature of a broadly applicable class of physical processes, Both landscape evolution and regional seismicity appear to be examples of self-organized critical phenomena, A variety of statistical models have been proposed to model landforms, including diffusion-limited aggregation, self-avoiding percolation, and cellular automata, Many authors have studied the behavior of multiple slider-block models, both in terms of the rupture of a fault to generate an earthquake and in terms of the interactions between faults associated with regional seismicity, The slider-block models exhibit a remarkably rich spectrum of behavior; two slider blocks can exhibit low-order chaotic behavior, Large numbers of slider blocks clearly exhibit self-organized critical behavior.
