CHIMAL EGUIA, Juan Carlos. On Some Properties of the Sandpile Model of Self-Organized Critical Systems. Comp. y Sist. [online]. 2004, vol.8, n.2, pp. 106-118. ISSN 1405-5546.

In this paper we analyze the sandpile model proposed by Bak, Tang and Wiesenfeld as the canonical example of self-organized critical systems. We find that the sandpile-model can reproduce staircase graphics and also that the distribution of large avalanches recurrence times in this model is log-normal. We also find that the slope of cumulative activity characterize a "province" of generation of avalanches in the same way as the seismic or evolutionary provinces do.
