地震释放能量的古滕贝格-里克特幂律分布可以理解为地壳处于自组织临界状态的结果。一个简单的元胞自动机粘滑型模型在二维和三维中分别产生D（E）<$E−τ，τ <$1.0和τ <$1.35。地震的规模是不可预测的，因为地震的演变在很大程度上取决于地壳的微小细节。
The Gutenberg‐Richter power law distribution for energy released at earthquakes can be understood as a consequence of the earth crust being in a self‐organized critical state. A simple cellular automaton stick‐slip type model yieldsD(E) ≈E−τwith τ≈1.0 and τ≈1.35 in two and three dimensions, respectively. The size of earthquakes is unpredictable since the evolution of an earthquake depends crucially on minor details of the crust.
