Fault slip envelope: a new parametric investigation tool for fault slip based on geomechanics and 3-D fault geometry

A Fault Slip Transient on the North Anatolian Fault

Fault structure, frictional properties and mixed-mode fault slip behavior

a r t i c l e i n f o Recent high-resolution GPS and seismological data reveal that tectonic faults exhibit complex, multi-mode slip behavior including earthquakes, creep events, slow and silent earthquakes, low-frequency events and earthquake afterslip. The physical processes responsible for this range of behavior and the mechanisms that dictate fault slip rate or rupture propagation velocity ...

Slip complexity in earthquake fault models.

We summarize studies of earthquake fault models that give rise to slip complexities like those in natural earthquakes. For models of smooth faults between elastically deformable continua, it is critical that the friction laws involve a characteristic distance for slip weakening or evolution of surface state. That results in a finite nucleation size, or coherent slip patch size, h*. Models of sm...

Constraining fault constitutive behavior with slip heterogeneity

We explore features of rupture dynamics that (1) lead to slip heterogeneity in earthquake ruptures and (2) maintain conditions that permit slip heterogeneity in subsequent events. Our 3-D finite-element simulations of magnitude 7 events on a vertical, planar strike-slip fault show that the conditions that lead to slip heterogeneity remain in place after large events when the initial shear stres...

Spatio-temporal Complexity of Slip on a Fault

Three-dimensional analyses are reported of slip on a long vertical strike-slip fault between steadily driven elastic crustal blocks. A rateand state-dependent friction law governs motion on the fault; the law includes a characteristic slip distance L for evolution of surface state and slip weakening. Because temperature and normal stress vary with depth, frictional constitutive properties (velo...
