Fault Friction During Simulated Seismic Slip Pulses

Theoretical studies predict that during earthquake rupture faults slide at non-constant slip velocity, however it is not clear which source time functions are compatible with the high velocity rheology of faults. Here we present results from friction experiments history, employing a well-known seismic solution kinematics. The evolution in shows strong dependence on applied and parameters relevant to energetics faulting scale impulsiveness function. When comparing constitutive models strength against our experimental demonstrate fault directly controlled by temperature off fault. Flash heating predicts weakening behavior short timescales, but larger timescales better predicted viscous creep rheology. We use steady-state pulse test compatibility measurements imposed rate history stress elastodynamic equilibrium. Whilst some observed, indicates acceleration deceleration might be more rapid than experiments.
