A detailed field and experimental investigation of the mechanisms responsible for fault zone weakness will be conducted by collaborators with expertise in the natural and experimental deformation of rocks. The study will concentrate on fault gauge from the San Andreas, Punchbowl and San Gabriel faults as these faults are thought to have slipped under small resolved shear stresses. The results of this study will provide an independent estimate of the mechanisms responsible for slip localization along faults of the San Andreas system, and will be of considerable importance to studies of major shallow-level fault zones worldwide.

具有岩石自然和实验变形专业知识的合作者将对导致断裂带软弱的机制进行详细的现场和实验研究。这项研究将集中于圣安德烈亚斯、彭奇堡和圣加布里埃尔断层的断层测量，因为这些断层被认为是在小的可分辨剪应力下滑动的。这项研究的结果将为圣安德烈亚斯系统沿断层滑动定位的机制提供一个独立的估计，并将对世界范围内主要浅层断裂带的研究具有相当重要的意义。
