Pinon Flat Observatory: A Facility for Studies of Crustal Deformation

要求为皮诺平台天文台两年的业务提供经费，作为研制和评价地震和地壳变形仪器的研究设施，并利用这些传感器监测南加州圣安德烈亚斯和圣哈辛托断层系统附近的一个构造活跃区域。该设施的一半费用将由美国地质调查局提供，另一半由美国国家科学基金会要求。来自许多机构的研究人员在天文台安装了各种各样的地球物理仪器，包括一些非常稳定和精确的应变仪和倾斜仪。这些高质量仪器的记录对于测量与地震和其他构造过程有关的地壳变形以及为评估新仪器提供参考标准是必不可少的。

Funds are requested for two years of operation of the Pinon Flat Observatory as a research facility for the development and evaluation of seismic and crustal deformation instruments and for using these sensors to monitor a tectonically active region near the San Andreas and San Jacinto fault system in southern California. One half of the cost of the facility will be furnished by the U.S. Geological Survey and the other half is requested of NSF. Investigators form many institutions have installed a wide range of geophysical instruments at the observatory, including some extremely stable and precise strainmeters and tiltmeters. Records from these high-quality instruments are essential for measuring crustal deformation associated with earthquakes and other tectonic processes and for providing reference standards against which to evaluate new instruments.
