Caldarelli, Guido and Frondoni, Raffaella and Gabrielli, Andrea and Montuori, Marco and Retzlaff, Rebecca and Ricotta, Carlo Percolation in real wildfires. EPL (Europhysics Letters), 56 (4). pp. 510-516. ISSN 0295-5075 (2001)Full text not available from this repository.
This paper focuses on the statistical properties of wild-land fires and, in particular, investigates if spread dynamics relates to simple invasion model. The fractal dimension and lacunarity of three fire scars classified from satellite imagery are analysed. Results indicate that the burned clusters behave similarly to percolation clusters on boundaries and look denser in their core. We show that Dynamical Percolation reproduces this behaviour and can help to describe the fire evolution. By mapping fire dynamics onto the percolation models, the strategies for fire control might be improved.
