Abstract
Laboratory earthquakes exhibit characteristics of a low dimensional random attractor with a dimension similar to that of natural slow earthquakes. A model of stochastic differential equations based on rate and state-dependent friction explains the laboratory observations. We study the transition from stable sliding to stickslip events and find that aperiodic behavior can be explained by small perturbations in the stress state. Friction's nonlinear nature amplifies small scale perturbations, reducing the predictability of the otherwise periodic macroscopic dynamics.
