WinGeol/SedTec is a software package which simulates erosion and deposition in dependency of topography, fault movements, lithological properties and sea level. Sediment transport such as mass and suspension flows are induced by elevation or concentration differences between neighbouring cells. Grain size reduction during sediment transport is included into the model. The spatial distribution o...

The Hayward fault in California's San Francisco Bay area produces large earthquakes, with the last occurring 1868. We examine how physics-based dynamic rupture modeling can be used to numerically simulate earthquakes on not only fault, but also its connected companions north and south, Rodgers Creek Calaveras faults. Equipped a wealth of images this system, including those 3D geology geometry, ...

We report on measurements of residual stress up to 300 MPa with a microfocused synchrotron X-ray beam in quartz fragments in a cataclasite from the damage zone of the San Andreas fault, California (USA). Samples were extracted from the San Andreas Fault Observatory at Depth drill core at a depth of 2.7 km. Stresses were derived from lattice distortions observed on Laue diffraction images. These...

[1] Deformed fluvial terraces preserved over active thrust-related folds record the kinematics of folding as fault slip accumulates on the underlying thrust. In the Mackenzie Basin of southern New Zealand, the kinematics revealed by folded fluvial terraces along the active Ostler and Irishman Creek fault zones are inconsistent with traditional models for thrust-related folding in which spatiall...

A conceptual model is proposed for the generation of low-angle normal faults in Metamorphic Core Complexes. The model is based on three assumptions: (1) the isostatic response to normal fault motion is of regional extent; (2) when a fault segment is significantly rotated from the optimum angle of slip, relative to the crustal stress field, it is replaced by a new planar fault oriented in the op...

Understanding carbon dioxide (CO2) reservoir to surface migration is crucial successful capture and sequestration approaches; especially fault/reservoir interactions under injection pressure. Through seismic imaging, we explore regolith shallow stratigraphy across the Little Grand Wash fault. The presence of natural CO2 seeps, travertine tufa deposits confirm modern ancient fault-controlled lea...
