+ Faults can dominate the dynamic behaviour of Earth systems at scales from the entire planet to a few 10s of metres. They are an extreme example of localisation: feedback between forcing and response that results in self-reinforcing weakening that does not have a brake at the largest scale. Faults are *extreme* in the sense that their natural thickness is orders of magnitude below that of a typical tectonic simulation. At the tectonic scale, a fault is an infinitesimally thin surface across which the rock moves discontinuously by overcoming a frictional resistance. A finite element mesh (the mesh we use in Underworld) is a mechanism for representing continuous fields and there is not a native mechanism that perfectly represents a fault.
