地壳介质剪切波分裂研究的部分进展

Abstract

Abstract: Seismic shear waves split when traveling through anisotropic media, and the anisotropy in the crust is mainly the result of stress-aligned fluid-saturated grain-boundary cracks. Analysis of anisotropy-induced shear wave splitting is used for studying the feature of crustal media, the condition and variation of crustal stress, and earthquake forecast as well. It is also a new attempt to study the nature of faults by means of analysis of anisotropy in crust.

Key words: Shear-wave splitting, Anisotropy, Crust, Polarization, Time-delay, Stress
