This study will utilize the NEES "Liquidator" seismic vibrator in Las Vegas, as it is transported back to its home base in Austin from a project at Yucca Mountain, which is about 100 miles from Las Vegas. It will be used in a surface wave testing study to complement an existing project to characterize seismic response of the Valley. The equipment will be used to fill a vital data gap between shallow depths that are accessible with existing UNLV test equipment, and great depths that have been imaged through seismic refraction/reflection using explosive testing and group-wave velocity measurements from teleseisms. The overall purpose of the data collection is to map shear wave velocities (VS) to support earthquake site response analyses. The work will complement a multidisciplinary research effort by a woman-dominated team of faculty and students. It will also help the team to build expertise with its own, newly acquired "minivib" seismic source.

这项研究将利用拉斯维加斯的NEES“液化器”地震振动器，因为它是从尤卡山的一个项目运回奥斯汀的基地，尤卡山距离拉斯维加斯约100英里。 它将用于表面波测试研究，以补充现有的项目，以确定山谷的地震反应。 该设备将用于填补现有UNLV测试设备可进入的浅深度与使用爆炸测试和地震群波速度测量通过地震折射/反射成像的大深度之间的重要数据差距。 数据收集的总体目的是绘制剪切波速度（VS），以支持地震现场反应分析。 这项工作将补充一个由女性主导的教师和学生团队的多学科研究工作。 它还将帮助该团队利用自己新获得的“minivib”震源建立专业知识。
