Numerical model of seismic rupture

Abstract

Simple numerical models of the cellular automaton type have been proposed recently, as an analogy for seismic faults. Those showed interesting features of spontaneous rupture evolution or even seismic recurrence. It is possible to incorporate realistic rheology and tensorial physics into this kind of model, to extend it to a portion of crust instead of a single fault-plane and to simulate its time evolution. A numerical model based on physics of continuum media, instead of a cellular automaton, which simulates dynamic rupture in two dimensions is described. -from Authors
