Cellular automaton simulations with a N = 256 1-D lattice produced by a numerical code according to Charbonneau et al. (2001). The frequency distributions of peak energy dissipation rate P, total energies E, time durations T, and fractal avalanche volumes V are shown along with the fitted powerlaw slopes. Correlations between the fractal dimension D₁ and parameters E, P, and T are also shown, fitted in the ranges of P ≥ 50, E ≥ 50, T ≥ 5, and V ≥ 2. Only a representative subset of 2000 events are plotted in the scatterplots.
