Abstract
We present a cellular automaton approach involving two variables and investigate its behavior with respect to self-organized criticality (SOC). It can be seen as a generalization of the Bak-Tang-Wiesenfeld and Olami-Feder-Christensen models and exhibits SOC behavior, too. In contrast to these models it leads to a power law distribution of the cluster sizes with an exponent close to one, as it occurs in earthquakes and landsliding processes, without any tuning.Keywords
