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.

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.

Fault rock evolution and fluid flow in sedimentary basins [PDF]
, 1989 Structural studies have been undertaken in two extensional fault regimes associated with post-Caledonian basin-forming events in northern Scotland. A combination of detailed mapping and microstructural analysis has revealed the deformation processes and ...

Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]
, 2002 We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).

Scientific Reports, 2022 The 2010 M W 7.2 El Mayor-Cucapah, Mexico, earthquake ruptured multiple faults with different faulting mechanisms. Resolving the earthquake rupture process and its relation to the geometric fault complexities is critical to our understanding of the ...

Geomatics, Natural Hazards & Risk, 2020 The moderate-size 2010 Yushu earthquake (Mw 6.9) caused severe seismic damage around the source region which is situated on the sparsely populated hinterland of the Tibetan Plateau. But until now the mechanisms have not been well understood. To this end,

Earthquake Science, 2022 The Xiluodu (XLD) reservoir is the second largest reservoir in China and the largest in the Jinsha River basin. The occurrence of two M > 5 earthquakes after reservoir impoundment has aroused great interest among seismologists and plant operators.

Remote Sensing, 2018 Seismogenic fault geometry, especially for a blind fault, is usually difficult to derive, based only on the distribution of aftershocks and interference fringes of Interferometric Synthetic Aperture Radar (InSAR).

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 ...

Major California faults are smooth across multiple scales at seismogenic depth
Seismica, 2023 Surface traces of earthquake faults are complex and segmented on multiple scales. At seismogenic depth the detailed geometry of faults and earthquake rupture is mainly constrained by earthquake locations.
