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 کاملAsymmetry in elastic properties and the evolution of large continental strike-slip faults
[1] We use geodetic studies to quantify several cases of significant asymmetry in interseismic and coseismic effects along large continental strike-slip faults using simple two-dimensional edge dislocation models. We first show that asymmetric elastic loading characterizes the present Main Marmara Fault, a portion of the North Anatolian Fault along the northern margin of the Sea of Marmara. The...
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 کاملMajor intracontinental strike-slip faults and contrasts in lithospheric strength
A large fraction of major intracontinental strike-slip faults, defi ned here as those slipping at rates of ~10 mm/yr or more, lie adjacent to relatively strong regions, such as oceanic lithosphere or Precambrian shields. We suggest that such faults form adjacent to discontinuities in strength, because strain in a continuous medium must concentrate near such strong objects. Concentration in stra...
