Dynamics of fault interaction: parallel strike-slip faults
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1993We 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.

Fault Displacement Hazard for Strike-Slip Faults
Bulletin of the Seismological Society of America, 2011In this paper we present a methodology, data, and regression equations for calculating the fault rupture hazard at sites near steeply dipping, strike-slip faults. We collected and digitized on-fault and off-fault displacement data for 9 global strike- slip earthquakes ranging from moment magnitude M 6.5 to M 7.6 and supplemented these with ...

Segmentation along Strike-Slip Faults Revisited
Pure and Applied Geophysics, 2009Fault segmentation and fault steps and their evolution are relevant to the dynamics and size of earthquake ruptures, the distribution of fault damage zones and the capacity of fault seal. Furthermore, segment interactions and coalescence are the fundamental processes for fault growth.

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.
