摘要

本期《地球物理学年鉴》特刊“地震各向异性和横波分裂:成就和观点”源于欧洲地震委员会ESC 2021年会议第37届大会(S10)的一次会议，该会议计划于2021年9月21日在希腊科孚岛举行，但由于covid - 19大流行是虚拟的。会议和本期特刊的主题是地震各向异性在研究从上地壳到内核的地球内部中所起的关键作用。剪切波分裂是研究地震各向异性最有效的方法之一，它可以识别上地幔的性质和地球动力学，并根据应力状态识别上地壳中流体饱和微裂缝的存在。根据地震或环境噪声记录，可以评估方位各向异性和径向各向异性，从而探测地震层状特征，重建三维地震结构

Seismic anisotropy and shear-wave splitting: Achievements and perspectives: foreword

This special issue of Annals of Geophysics “Seismic anisotropy and shear-wave splitting: Achievements and perspectives” originates from a session (S10) of the 37th General assembly of the European Seismological commission ESC 2021 Conference which was planned to take place on 21 September 2021, in Corfu Greece, but due to the Covid19 pandemic was Virtual. The main theme of the session and of this special issue was the crucial role of seismic anisotropy in investigating the Earth’s interior from the upper crust to the inner core. Shear-wave splitting, one of the most effective ways to study seismic anisotropy, can identify the properties and the geodynamics of the upper mantle, and identify the presence of fluid-saturated microcracks, oriented according to the stress regime, in the upper crust. Azimuthal anisotropy and radial anisotropy can be assessed from earthquake or ambient noise recordings to detect the seismic layered features and to rebuild the 3D seismic structure
