in which τ is the shear strength (Pa) of the fault, μ is the friction coefficient (−), σ n is the normal stress (Pa) acting on the fault, P f is the pore ,fluid, pressure (Pa), and S 0 ≥ 0 is the cohesive strength (Pa) [Byerlee, 1978; Hubbert and Rubey, 1959].There are two broad scenarios by which fault reactivation can occur. The first is related to changes in the (effective) stress ...
