这笔拨款为建造第二台半便携式激光长基线应变仪的费用提供部分支持，用于测量与位于圣安德烈亚斯断层系统南端的现有应变仪正交的潮汐应变。这些测量将被用于尝试模拟三维弹性不均匀性和非弹性反应，这对于确定地震易发地区的力学行为很重要。使用两种仪器提供了一种测量断层附近地壳应变的新方法。* * *
英文摘要
9528113 Agnew This grant provides partial support for the costs of constructing a second, semi-portable, laser- based, long-baseline strainmeter to make measurements of tidal strains orthogonal to an existing strainmeter situated at the southern termination of the San Andreas fault system. These measurements would be used in an attempt to model the 3-D elastic inhomogeneities and inelastic responses that are important in determining the mechanical behavior of earthquake prone regions. The use of two instruments provides a novel approach to measuring crustal strain near faults. ***
