# Forest Fire Simulation

The following simulation is a running cellular automaton on a grid using the Von Neumann neighborhood. A cell is either (1) empty (highlighted in brown), (2) occupied by a tree (highlighted in green) or burning (highlighted in red). I implemented the model proposed by Drossl and Schwabl  [1]:

1. A burning cell turns into an empty cell
2. A tree will burn if at least one neighbor is burning
3. A tree ignites with probability $$\gamma$$ even if no neighbor is burning
4. An empty space fills with a tree with probability $$\alpha$$

In this example I use $$\gamma = 5.0 \cdot 10^{-6}$$ and $$\alpha = 0.01$$ and $$150 \times 150$$ cells.
