|We dcument fault propagation around restraining bendswithin wet kaolin and demonstrate that the fault evolve to increase efficiency.
|The bright pink highlight regions of high shear strain. The image at right shows a snapshot towards the end of the experiment. On the left side of the restraining bend, two echelon faults are active. The inner fault is dying out while the outer fault picks up activity.|
Justin shows that slip distribution along faults changes with rather small changes in fault geometry. In the figure above, Justin shows that variations in tectonic loading may favor either strike-slip along the San Andreas fault or the Eastern California Shear Zone.
