  abstract = {{W}hile the notion that injecting fluids into the subsurface can reactivate faults by reducing frictional resistance is well established, the ensuing evolution of the slip is still poorly understood. {W}hat controls whether the induced slip remains stable and confined to the fluid-affected zone or accelerates into a runaway earthquake? {A}re there observable indicators of the propensity to earthquakes before they happen? {H}ere, we investigate these questions by modeling a unique fluid-injection experiment on a natural fault with laboratory-derived friction laws. {W}e show that a range of fault models with diverging stability with sustained injection reproduce the slip measured during pressurization. {U}pon depressurization, however, the most unstable scenario departs from the observations, suggesting that the fault is relatively stable. {T}he models could be further distinguished with optimized depressurization tests or spatially distributed monitoring. {O}ur findings indicate that avoiding injection near low-residual-friction faults and depressurizing during slip acceleration could help prevent large-scale earthquakes.},
