Recent geologic and geodetic data indicate that a zone, termed the Eastern California shear zone, of right lateral shear has been long-lived and is still active. However, within the shear zone, there is conflicting evidence of which strand is active-geologic data require that the Death Valley-Furnace Creek fault zone is the principal locus of shear, while geodetic data appear to favor the Owens Valley fault. Of the several possible explanations of this paradox, this project will test the model that the locus of shear is currently in the process of shifting from the former to the later. The results are also expected to improve understanding of the fundamental mechanisms that control fault interactions and slip partitioning between parallel strike-slip faults and connecting normal faults.

最近的地质和大地测量数据表明，一个被称为东加州剪切带的右旋剪切带已经存在很长时间，并且仍然活跃。 然而，在剪切带内，有相互矛盾的证据，其中链是活跃的地质数据要求，死亡谷炉溪断层带是剪切的主要轨迹，而大地测量数据似乎有利于欧文斯谷故障。 在这一悖论的几种可能的解释中，本项目将测试剪切轨迹目前正处于从前者向后者转移的过程中的模型。 这些结果也有望提高对控制平行走滑断层和连接正断层之间断层相互作用和滑动划分的基本机制的理解。
