Multicycle dynamics of nonplanar strike-slip faults
[1] We perform two-dimensional dynamic models of strike-slip faults with a change in strike (a bend) over multiple earthquake cycles to examine the long-term effects of nonplanar fault geometry. A viscoelastic model (a proxy for off-fault deformation and tectonic loading) is introduced for the interseismic process to avoid pathological stress buildup around the bend. A finite element method wit...
متن کامل3D stochastic rock fracture modeling related to strike-slip faults
Fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the Earth’s crust. Furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. In this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...
متن کاملHeterogeneous 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...
متن کاملThe Dynamics of Strike-Slip Step-Overs with Linking Dip-Slip Faults
Fault step-overs with linking dip-slip faults are common features on long strike-slip fault systems worldwide. It has been noted by various researchers that under some circumstances, earthquakes can jump across fault step-overs to cascade into large events, while under other circumstances rupture is arrested at stepovers. There is also evidence that fault step-overs may be preferential location...
متن کاملStructural 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 ...
