A Review of the Seismic Anisotropy and Its Applications
Abstract
It's briefly introduced of the new progress of seismic wave in anisotropic media and its application in geodynamics, earthquake monitoring and resource exploration. Presently, numerical modeling and physical experiments are used for probing the laws on wave propagation in anisotropic media. Shear wave splitting, the azimuthal variation of Pn wave and surface wave imaging are applied in the research of the structure and material exchangement in the earth, the stress field and the formation of earthquake. Moreover, in resource exploration, the anisotropy theory is used to resolve the non closure of crossover line, the middle and long spread moveout, time depth conversion, the distribution of fractures and so on.
