The crustal deformation mechanism of southern Chuandian block: constrained by S wave velocity and its azimuthal anisotropy

Abstract We construct the 3D Shear wave velocity and azimuthal anisotropy images in the southern Chuandian block using phase velocity dispersion of Rayleigh wave in the period of 5–45 s. The images show two extensive low-velocity zones with a depth range of 20–40 km. The west range of the low-veloci...
