Linear and nonlinear stability of rate-and-state faults
Robert C. Viesca, Dmitry I. Garagash
Models of faults incorporating slip rate- and state-dependent friction have reproduced phenomena from spontaneous slow, aseismic slip to earthquake-generating dynamic rupture. Nume…

Asymptotic solutions for self-similarly expanding fault slip induced by fluid injection at constant rate
Robert C. Viesca
We examine the circular, self-similar expansion of frictional rupture due to fluid injected at a constant rate. Fluid migrates within a thin permeable layer parallel to and contain…

Non-linear stability analysis of slip in a single-degree-of-freedom elastic system with frictional evolution laws spanning aging to slip
Federico Ciardo, Robert C. Viesca
We present a non-linear stability analysis of quasi-static slip in a spring-block model. The sliding interface is governed by rate- and state-dependent friction, with an intermedia…
