Making Strainmeter Data Straightforward: Tools, Techniques, and Results to Assist the EarthScope User Community

我们正在帮助建立一个科学社区，使用地球范围板块边界观测站组件中应变仪的数据。现有的PBO钻孔应变仪数据强烈表明，现有的简单模型与已知的地球潮汐信号不相符。我们正在开发寻找仪器响应的方法和工具，并向社区提供描述和方法，使用户能够比现在更直接地解释数据。我们正在测试使用不同输入信号（潮汐、气压载荷和地震波）的模型，并正在为井眼应变仪的观察行为开发力学模型，特别是它们对施加应变的响应，包括地形变形和井眼附近的压裂。我们正在继续开发两个软件包，一个是用于分析应变仪数据的软件包（PIASD），另一个是用于计算海洋潮汐载荷的软件包（SPOTL）。

We are helping to develop a scientific community that uses data from the strainmeters in the Plate Boundary Observatory component of EarthScope. The available PBO borehole strainmeter data strongly suggests that the simple models available do not fit the known signals from the Earth tides. We are developing methods and tools for finding the instrument response, and providing the community with descriptions and methods that will allow users to interpret the data more straightforwardly than is now possible. We are testing models that use different input signals (tides, air pressure loading, and seismic waves), and are Developing mechanical models for the observed behavior of borehole strainmeters, particularly their response to applied strain, including distortions from topography, and from fracturing near the borehole. We are continuing to develop two software packages, one (PIASD) for the analysis of strainmeter data and the other (SPOTL) for computing of ocean tidal loading.
