Earthquake Nucleation Along Faults With Heterogeneous Weakening Rate

Abstract

• The nucleation length of heterogeneous faults with multi-scale asperities of weakening rate can be predicted for slip-dependent friction. • Our theory accounts for the transition in fault stability regimes, from the traditional "weakest defect" theory to a homogenized behavior. • Only asperities larger than the nucleation length participate actively in the fault stability, while the influence of small heterogeneities can be averaged.
