Abstract: Shear wave splitting analysis is one of the most commonly used techniques in crust and mantle deformation. In this paper, we show the derivation process of theoretical equations of the split wave, introduce several shear wave splitting analysis methods, and then summarize the progress of research on crustal anisotropy using shear wave splitting analysis. Although the shear wave splitting analysis method is widely used in the study on crustal anisotropy, it also has some inherent limitations. A reliable method and procedure of data processing to accurately obtain shear wave splitting parameters was expected in future.
