Continuous Crustal Deformation Measurement: Data Analysis and Instrument Development

该奖项授予对南加州活跃地壳形变的研究，这些研究领域应该是对过去和未来大地测量研究的补充。以前的工作侧重于使用Pinon Flat天文台(PFO)的仪器分析数据，以及开发高质量测量所需的技术。PIS将继续这样做，重点是如何利用现有的形变数据，包括来自PFO和大地测量的数据，来检验关于断裂带性质的假设。他们将继续对南加州的USGS EDM网络数据进行详细的检查，致力于解决在观测到的线路长度变化情况下解决断层面位移的困难反问题。这项研究不仅应该提高对断层力学的理解，而且应该证明对规划未来活动断层附近的大地测量是有价值的。该奖项属于NEHRP。

This award studies of active crustal deformation in southern California, in research areas that should complement past and future geodetic studies. Previous work has emphasized analysis of data from with instruments Pinon Flat Observatory (PFO), along with the development of the techniques needed for high-quality measurements. The PIs will continue this, focusing on ways to use existing deformation data, both from PFO and from geodetic surveys, to test hypotheses about the nature of fault zones. They will continue a detailed examination of the USGS EDM-network data in southern California, working on the difficult inverse problem of solving for fault-plane displacements given the observed line-length changes. This investigation should improve not only understanding of fault mechanics, but should also prove valuable for planning future geodetic measurements near active faults. This award falls under NEHRP.
