Fault slip envelope: a new parametric investigation tool for fault slip based on geomechanics and 3-D fault geometry [PDF]
Solid Earth, 2019 By combining a 3-D boundary element model, frictional slip theory, and fast computation method, we propose a new tool to improve fault slip analysis that allows the user to analyze a very large number of scenarios of stress and fault mechanical property ...

Velocity‐ and slip‐dependent weakening in simulated fault gouge: Implications for multimode fault slip [PDF]
Geophysical Research Letters, 2015 AbstractIn addition to the velocity dependence of friction, slip dependence may play a major role before and during earthquake slip in fault zones. We performed laboratory friction experiments on simulated fault gouges, measuring both the velocity and slip dependence of friction in velocity step tests.

The structure and composition of exhumed faults, and their implications for seismic processes [PDF]
, 2000 Field studies of faults exhumed from seismogenic depths provide useful data to constrain seismologic models of fault zone processes and properties. Data collected on the San Andreas Fault in the San Gabriel Mountains has shown that large-displacement ...

Predicting fault slip via transfer learning. [PDF]
Nat Commun, 2021 Abstract Data-driven machine-learning for predicting instantaneous and future fault-slip in laboratory experiments has recently progressed markedly due to large training data sets. In Earth however, earthquake interevent times range from 10's-100's of years and geophysical data typically exist for only a portion of an earthquake cycle.

Fault slip distribution and fault roughness [PDF]
Geophysical Journal International, 2011 We present analysis of the spatial correlations of seismological slip maps and fault topography roughness, illuminating their identical self-affine exponent. Though the complexity of the coseismic spatial slip distribution can be intuitively associated with geometrical or stress heterogeneities along the fault surface, this has never been demonstrated.

The Spectrum of Fault Slip in Elastoplastic Fault Zones
Earth and Planetary Science Letters, 2023 Natural faults are typically surrounded by damage zones that exhibit inelastic material response. This study investigates the role of fault zone strength in modulating the spectrum of fault slip across different spatio-temporal scales. We carry out long-term simulations of seismic and aseismic slip for an elastoplastic spring slider model with rate-and-

The slow slip of viscous faults [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractWe examine a simple mechanism for the spatiotemporal evolution of transient, slow slip. We consider the problem of slip on a fault that lies within an elastic continuum and whose strength is proportional to sliding rate. This rate dependence may correspond to a viscously deforming shear zone or the linearization of a nonlinear, rate‐dependent ...

Strike-slip fault terminations at seismogenic depths : the structure and kinematics of the Glacier Lakes fault, Sierra Nevada United States [PDF]
, 2008 Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth.

The geometry and thickness of deformation-band fault core and its influence on sealing characteristics of deformation-band fault zones [PDF]
, 2005 Deformation-band faults in high-porosity reservoir sandstones commonly contain a fault core of intensely crushed rock surrounding the main slip surfaces.

Anatomy of Strike Slip Fault Tsunami-genesis [PDF]
Coastal Engineering Proceedings, 2021 Tsunami generation from earthquake induced seafloor deformations has long been recognized as a major hazard to coastal areas. Strike-slip faulting has generally been believed as insufficient for triggering large tsunamis, except through the generation of submarine landslides.
