Seismic Radial Anisotropy of the Southern Tibetan Rifts from Ambient Noise Adjoint Tomography: Basal Shear and Localized Crustal Weak Zones Promote Rifting

We performed ambient noise adjoint tomography of crustal shear-wave velocity and seismic radial anisotropy beneath three rifts in southern Tibet to reveal their intracrustal deformation characteristics. The dataset consists of four parts. CCFs_TT.zip and CCFs_ZZ.zip contain the cross-correlation functions for all station pairs. Model_Vs is the 3-D crustal isotropic (mean) shear-wave velocity model for the southern Tibetan rift region, and Model_RA is the 3-D crustal radial anisotropy model for the same region.
