Postearthquake Deformation Monitoring of the Los Angeles Region: Continuous GPS Monuments

这项研究的目的是在1994年北岭地震发生地区附近的南加州的GPS（全球定位系统）永久网络的15个站点扩展中开发和安装5个高稳定性大地测量纪念碑。据估计，未锚定的大地测量纪念碑的稳定性是影响该网络在某些地点的数据质量的主要因素。这项工作将能够研究其中5个场址的稳定性，并制定计划，使未来的建设能够与外部来源签订合同。除了这笔拨款外，阵列扩展的主要资金将来自美国宇航局、美国地质勘探局和南加州地震中心。该项目是对国家减少地震危害计划的贡献，由北岭地震紧急拨款支持。＊＊＊

9416336 Agnew This research is to develop and install 5 high-stability geodetic monuments in a 15 station expansion of the GPS (Global Positioning System) permanent network in southern California around the area of the 1994 Northridge earthquake. The stability of unanchored geodetic monuments is estimated to be the major factor in the quality of data from this network at some sites. This work will enable the study of the stability of 5 of the sites and produce plans that well enable future construction to be contracted to external sources. Major funding for the array expansion is to come from NASA, USGS, and the Southern California Earthquake Center in addition to this grant. This project is a contribution to the National Earthquake Hazard Reduction Program and is supported by the Northridge Earthquake Emergency Appropriation. ***
