Climatic influence on the expression of strike-slip faulting

Geology, 2022
Abstract Earthquakes on strike-slip faults are preserved in the geomorphic record by offset land-forms that span a range of displacements, from small offsets created in the most recent earthquake (MRE) to large offsets that record cumulative slip from multiple prior events.

Volcanism in Reverse and Strike-Slip Fault Settings

2009
Traditionally volcanism is thought to require an extensional state of stress in the crust. This review examines recent relevant data demonstrating that volcanism occurs also in compressional tectonic settings associated with reverse and strike-slip faulting.

Dynamics of fault interaction: parallel strike-slip faults

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1993
We use a two‐dimensional finite difference computer program to study the effect of fault steps on dynamic ruptures. Our results indicate that a strike‐slip earthquake is unlikely to jump a fault step wider than 5 km, in correlation with field observations of moderate to great‐sized earthquakes.

Radiation from a strike-slip fault

Bulletin of the Seismological Society of America, 1959
abstract 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

Analysis of the dynamics of strike slip faulting

Journal of Geophysical Research, 1973
Strike slip generated by wave motions and wave motions generated by strike slip are analyzed for vertical surface faults on which motion is opposed by a frictional shear stress, which is assumed to increase linearly with depth. The fault is a plane of discontinuity in a homogeneous, isotropic, linearly elastic half-space. The half-space is subjected to

Earthquake instability on a strike‐slip fault

Journal of Geophysical Research: Solid Earth, 1979
A strain softening model for earthquake instability on a long, vertical, strike‐slip fault is analyzed using continuously distributed screw dislocations. The fault zone constitutive law is represented by a Gaussian‐shaped friction law in which slip softening occurs beyond the peak stress.

Strike-Slip Fault

2014
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.

Sinuosity of strike-slip fault traces

Geology, 1975
A 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, 1980
The 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, 1989
Abstract 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.
