Piggyback Recording of a Refraction Experiment for Basin Structure

A gravity survey published in 2000 found unexpectedly deep sub-basins below Reno, NV. Due to the potential for these deep basins to trap and amplify earthquake ground motion, their existence and depth must be confirmed by a second geophysical technique. A seismic refraction survey of a geothermal resource 15 km south of the basins will allow a line of 15 PASSCAL Texans to record the delays associated with the basins.

2000年发表的一项重力勘探研究显示，美国内华达州里诺市（Reno, NV）地下存在超乎预期的深次级盆地。鉴于此类深盆地具备截留并放大地震地面运动的潜力，必须通过第二种地球物理技术验证其存在与埋藏深度。针对该盆地以南15公里处一处地热资源开展的地震折射勘探，可借助由15台PASSCAL设备组成的测线，记录与该盆地相关的地震波延迟。
