Effects of Anisotropy Observed from Surface Waves

本研究的目的是分离太平洋地震表面波横向非均质性和方位非均质性对地震表面波极化的影响。极化异常是探测各向异性的良好工具。结果将被绘制出来，以确定各向异性效应是否与海底年龄有关。这项技术的成功发展将真正有助于我们了解海洋地壳的各向异性，这是对表面波传播的一个重要但被忽视的影响。

The objective of this research is to separate the effects on seismic surface wave polarizations of lateral heterogeneity and azimuthal anisotropy in the Pacific Ocean. Polarization anomalies are a good tool for detecting anisotropy. The results will be mapped to see if anisotropy effects correlate to ocean floor age. The successful development of this technique would be a real contribution to our knowledge of anisotropy in the oceanic crust which is an important, but neglected, effect on surface wave propagation.
