尽管认识到速度是处理和解释地震数据的中心参数，但直到最近，在地震数据处理和解释中，它的方向依赖性一直被忽略。虽然P波数据中各向异性的存在常常被忽视，地下是各向异性的，并且越来越多的证据表明各向异性是相当普遍的，但是错误假设各向同性的处理产生错误的图像，从而产生错误的解释。
Despite the recognition that velocity is the central parameter in processing and interpretation of seismic data, until recently its directional dependence has been ignored in seismic data processing and interpretation. Although the existence of anisotropy in P-wave data can often go unnoticed, where the subsurface is anisotropic, and evidence increasingly suggests that anisotropy is rather pervasive, processing that makes the erroneous assumption of isotropy yields erroneous images and, thus, interpretations.
