This award provides funding for University of California - Santa Barbara (UCSB) to purchase advanced instrumentation and do associated work for the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) - Permanently Instrumented Field Sites at - Wildlife site in Garner Valley, that will be operated by NEES Consortium, Inc., as a national shared use facility during FY 2005 - FY 2014. This award provides funding for the necessary instrumentation to augment the field measurements to provide additional critical data for future analyses and compare it with the data from old site that has been instrumented since 1982.. This will address the major challenges outlined the 2003 National Research Council report entitled "Preventing Earthquake Disasters: The Grand Challenge in Earthquake Engineering Research - A Research Agenda for the Network for Earthquake Engineering." The instrumentation was selected with input from project advisory committee and includes: a fifth downhole accelerometer in the liquefiable layer in the downhole accelerometer array, replacing the analog instruments with modern instruments (two shallow episensor force-balance accelerometers) to allow telemetering of the data to NEESgrid, replacement of surface accelerometer and analog DAQ with K-2 system, and three electrically transduced piezometers to measure pore pressures. This augmented instrumentation will enable researchers to provide additional data to fully analyze response of the Wildlife sites to future earthquake shaking and to allow comparison and verification of future records with those recorded during 1987 Superstition Hills earthquake. This award is funded by the NSF NEES Major Research Equipment and Facilities Construction (MREFC) project and is a component of the National Earthquake Hazards Reduction Program (NEHRP).

该奖项为加州大学圣巴巴拉分校（UCSB）提供资金，用于购买先进的仪器设备，并为加纳谷野生动物保护区的乔治·e·布朗地震工程模拟网络（NEES）永久仪器现场站点进行相关工作，该站点将由NEES财团公司运营，在2005 - 2014财年期间作为国家共享使用设施。该奖项为必要的仪器提供资金，以增加现场测量，为未来的分析提供额外的关键数据，并将其与自1982年以来使用仪器的旧站点的数据进行比较。这将解决2003年国家研究委员会题为“预防地震灾害：地震工程研究的重大挑战——地震工程网络的研究议程”的报告中概述的主要挑战。该仪器是根据项目咨询委员会的意见进行选择的，包括：在井下加速度计阵列的可液化层中安装第五个井下加速度计，用现代仪器（两个浅层传感器力平衡加速度计）取代模拟仪器，以便将数据遥测到NEESgrid，用K-2系统取代地面加速度计和模拟DAQ，以及三个电换能式压电计来测量孔隙压力。这种增强的仪器将使研究人员能够提供额外的数据，以充分分析野生动物遗址对未来地震的反应，并允许将未来的记录与1987年迷信山地震的记录进行比较和验证。该奖项由NSF NEES主要研究设备和设施建设（MREFC）项目资助，是国家减少地震灾害计划（NEHRP）的一个组成部分。
