We present a model for dynamic weakening of faults based on local flash heating at microscopic asperity contacts coupled to bulk heating at macroscopic scaleWe estimate the fracture energy G associated with that rheology and find that for constant slip rate histories G scales with slip as G at small slip, while G at large slipThis prediction is quantitatively consistent

We present a model for dynamic weakening of faults based on local flash heating at microscopic asperity contacts coupled to bulk heating at macroscopic scaleWe estimate the fracture energy G associated with that rheology and find that for constant slip rate histories G scales with slip as math formula at small slip, while math formula at large slip.

Beyond mm slip, the fracture energy from flash heating is much smaller than for earthquakes, implying that other dissipation processes dominate (e.g thermal pressurization)This is consistent with previous estimates for the relative contribution of flash heating versus thermal pressurization [ Brantut and Rice , ].
