Abstract


Based on the seismic data of near-field source from Shandong Seismic Network, the study obtained the shear-wave splitting parameters from multiple stations. The results show that dominant directions of polarizations of fast shear-waves reflect the spatial distribution characteristics of tectonic stress in this area, CHD and LIS stations show 2 dominant direction, it reveals that the crustal seismic anisotropy in Shandong area is constrained by regional stress background, local failure and structure.
