Influence of spatially variable fault friction on tunnel-induced fault stability
Results in EngineeringThe activation of fault slip due to the redistribution of stresses after tunnel excavation is a major tunnel hazard. Although the angle of friction of the fault controls the stability, existing methods use deterministic analyses, ignoring its spatial ...

Thermobaric Activation of Fault Friction
Geophysical Research LettersThe constitutive behavior of faults intervenes in virtually every aspect of the seismic phenomenon but is poorly understood, particularly regarding how effective normal stress affects the boundaries of the seismogenic zone.

Fault friction during simulated seismic slip pulses [PDF]
Journal of Geophysical Research: Solid Earth, 2021 <p>Theoretical studies predict that during earthquake rupture faults slide at non-constant slip velocity, however it is not clear which source time functions are compatible with the high velocity rheology of earthquake faults. Here we present results from high velocity friction experiments with non-constant velocity history, employing a ...

Fault rheology beyond frictional melting [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance During an earthquake, the mechanical work of friction along the fault is partly dissipated as heat, which results in rock melting and pseudotachylyte generation along the fault plane. Beyond this point, it is generally believed that Newtonian viscous forces regulate slip.

Distributed damage, faulting, and friction [PDF]
Journal of Geophysical Research: Solid Earth, 1997 We present a formulation for mechanical modeling of geological processes in the seismogenic crust using damage rheology. The seismogenic layer is treated as an elastic medium where distributed damage, modifying the elastic stiffness, evolves as a function of the deformation history.

Homogenization of fault frictional properties [PDF]
Geophysical Journal International, 2019 SUMMARY The frictional properties of large faults are expected to vary in space. However, fault models often assume that properties are homogeneous, or nearly so. We investigate the conditions under which the details of variations may be neglected and properties homogenized.

Seismic source dynamics, heterogeneity and friction
Annals of Geophysics, 1994 It has recently been proposed by several authors that stress distribution around active faults may become critical spontaneously. Other authors believe that heterogeneity is a permanent feature of fault planes.

Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]
, 2012 The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least
