The influence of fault geometry on small strike-slip fault mechanics

Structural evidence on strike slip Kinematic inversion of the Kushk-e-Nosrat Fault zone, Central Iran

NW-tending faults in Central Iran are expected to represent dominant dextral components due to their orientation with respect to the northward motion of the Arabian Plate with respect to Eurasia. However, previously published works, as well as the focal mechanism solution of the area's earthquakes, indicate evidence of sinistral kinematic along the major faults in Central Iran. Here we present ...

Strike-slip fault patterns on Europa: Obliquity or polar wander?

Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...

Scaling of Fault Parameters for Continental Strike-Slip Earthquakes

The long-standing conflict between the predictions of elastic dislocation models and the observation that average coseismic slip increases with rupture length is resolved with application of a simple displacement-depth function and the assumption that the base of the seismogenic zone does not result from the onset of viscous relaxation but rather a transition to stable sliding in a medium that ...

A Fault Slip Transient on the North Anatolian Fault

Heterogeneous fault stresses from previous earthquakes and the effect on dynamics of parallel strike-slip faults

[1] We combine a viscoelastic model for the interseismic process and an elastodynamic model for the coseismic process to explore the dynamics (over multiple earthquake cycles) of two parallel strike-slip faults embedded in a two-dimensional full space. The step over fault geometry results in a buildup of heterogeneous fault stress near the step over. This heterogeneous stress accumulates at the...
