Geological Society of America Bulletin, 1988
The importance of strike-slip faulting was recognized near the turn of the century, chiefly from investigations of surficial offsets associated with major earthquakes in New Zealand, Japan, and California. Extrapolation from observed horizontal displacements during single earthquakes to more abstract concepts of long-term, slow accumulation of hundreds

Radiation from a strike-slip fault
Bulletin of the Seismological Society of America, 1959abstract Huygens' principle for elastodynamics has been applied to the problem of the radiation resulting from the introduction of a tear fault of finite length into an otherwise homogeneous medium. The fault has the following properties: (1) it is a surface across which the normal stresses vanish; (2) it has a rectangular shape with one

Surface slip variability on strike‐slip faults
Earth Surface Processes and Landforms, 2022AbstractSlip in strike‐slip earthquakes is spatially variable along a fault, but the degree to which variability over short length scales is inherent to the rupture process or introduced by interpretation and measurement has not been quantified. In this study, we examine the effects of interpretation error on apparent short‐wavelength variability in ...

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 ...

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.

Stress orientation responsible for formation of strike slip fault is described along with rheological controls on development of the fault. Conjugate strike slip faults are discussed with special reference to necessity of rotation of faults with progressive deformation.

Dating of the Karakorum Strike‐slip Fault
Acta Geologica Sinica - English Edition, 2001AbstractThis paper mainly discusses the timing of the Karakorum strike‐slip fault, and gives a brief introduction of its structures, offset, and deformational style. This fault strikes NNW‐SSE. Asymmetrical folds, stretching lineation, S‐C fabrics, feldspar and quartz s̀‐porphyroclasts, domino structure, shear cleavages and faults in the fault zone are

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.

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 ...
