Sinuosity of strike-slip fault traces
Geology, 1975A mechanical basis for the occurrence of curvature or sinuosity on strike-slip faults is postulated from finite-element simulation of an earthquake sequence on the Parkfield, California, segment of the San Andreas fault. Using discontinuity fields from measured displacements associated with the M ≅ 5.3 earthquakes of June 1966, motions along 16 km of ...

A stochastic model for strike-slip faulting
Journal of the International Association for Mathematical Geology, 1980The frequency of length of strike-slip faults in continental crust follows a lognormal probability distribution, and a nonlinear positive correlation exists between length and offset. These results appear to be scale-independent. An explanation of the observations is presented in terms of a stochastic model which treats the occurrence of faulting as a ...

Sidewall ripouts in strike-slip faults
Journal of Structural Geology, 1989Abstract Distinctive splay fault configurations in wallrocks associated with pseudotachylyte-bearing strike-slip fault structures at three different localities are recognized as ‘sidewall ripouts’. Sidewall ripout structures occur as asymmetric, doubly-tapered, fault-bounded lenses or slabs adjacent to a dominant planar fault surface.

Mechanics of strike-slip faulting with friction
Journal of Geophysical Research, 1968Strike-slip is analyzed for long, shallow surface faults of arbitrary dip on which motion is opposed by a frictional shear stress, which is assumed to increase linearly with depth. Static elastic analysis is used to find surface displacements and strains and to estimate the change in elastic potential energy, the frictional dissipation, and the ...

Strike-Slip Faults of Northern Venezuela
AAPG Bulletin, 1956ABSTRACT The Caribbean Mountains of northern Venezuela, and the area covered by the Caribbean Sea off the coast of Venezuela have been displaced to the east, relative to the land on the south, along a system of major strike-slip faults. From west to east this right-lateral fracture system consists of the following big faults: the Ocoa

A Mechanical Model for Deformation and Earthquakes on Strike-Slip Faults
pure and applied geophysics, 1986A two-dimensional model for stress accumulation and earthquake instability associated with strike-slip faults is considered. The model consists of an elastic lithosphere overlying a viscous asthenosphere, and a fault of finite width with an upper brittle zone having an elastoplastic response and a lower ductile zone having an elastoviscoplastic ...

Active strike-slip faulting in El Salvador, Central America
Geology, 2005Several major earthquakes have affected El Salvador, Central America, during the Past 100 yr as a consequence of oblique subduction of the Cocos plate under the Caribbean plate, which is partitioned between trench-orthogonal compression and strike-slip defor- mation parallel to the volcanic arc.

Geosciences Journal, 2000
A well exposed outcrop of Upper Carboniferous greywackes and slates at Crackington Haven, north Cornwall, shows several episodes of strike-slip faulting. Exposure-scale structures display may features typical of strike-slip fault systems including: splay faults, wing cracks, jogs, fault bends, fault branches, λ faults, rotated blocks, together with ...

Off-fault Deformation Associated with Strike-slip Faults
Environmental and Engineering Geoscience, 2018AbstractHabitable buildings can be protected from surface fault rupture by establishing structure “setback zones” similar in purpose to legally mandated zones in California and Utah. But post-earthquake surveys of offset and warped linear cultural features, believed to have been straight prior to the event, demonstrate that potentially damaging ...

Identification of strike‐slip faults in seismic sections
SEG Technical Program Expanded Abstracts 1987, 1987Transcurrent tectonism has been extensively reviewed in the literature during the last three decades, and its structural style in horizontal sections is well known. The increasingly large amount of seismic data available in the sedimentary basins all over the world has shown that transcurrent faults have very well defined characteristics in vertical ...
