Do Earthquakes Spread Like Wildfire? 26
sciencehabit writes "A simple model of forest fires could help explain the distribution of the sizes of earthquakes and their aftershocks, a theoretical physicist says. In the so-called Drössel-Schwabl model, trees sprout at random on a square grid like a vast checkerboard. Once the forest gets dense enough, lightning sets a random tree on fire, and fire spreads instantaneously among trees that occupy adjacent squares. The conflagration continues until there are no more neighbors to jump to. Then, the process starts all over again. In the team's model, the 'forest' is the plane of a fault cutting through Earth's crust, divided into a 10,000-by-10,000 grid. Sprouting trees correspond to the buildup of stress along the fault; burning areas, to the part of the fault that moves during a quake."

Very well.
In the so-called DrÃssel-Schwabl-rossdee model, Ford Pintos sprout at random on a square grid like a vast checkerboard. Once the traffic jam gets dense enough, a minor collision sets a random Pinto on fire, and fire spreads instantaneously among Pintos that occupy adjacent squares. The conflagration continues until there are no more neighbors to jump to. Then, the process starts all over again.
(Yes, I'm aware that Pintos weren't in reality the blazing firetraps I'm using them as here. Artistic license ftw!)
