Abstract

This paper examines the effects of shear heating due to frictional slip in a simple model of a fluid saturated fault zone. The experimentally motivated friction law includes dependence on the rate of slip and a state variable. Inclusion of the rate and state dependence is shown to eliminate a non-uniqueness that occurs when shear heating is included in a corresponding analysis for the commonly used, purely slip dependent friction relation (Garagash & Rudnicki, 2003a, b). Numerical simulations also show the strong effect of shear heating on the rapid (dynamic) slip that occurs following instability of the quasi-static solution.
