Seismic mantle tomography maps

Surface projected global horizontal seismic S-wave velocity anomaly maps for different mantle depths revealing the two large low shear-wave velocity provinces (LLSVPs) below the Pacific (named Jason) and Africa (named Tuzo). Shown is the S10MEAN model based on Doubrovine et al. (2016) averaging 10 tomography models allowing to compare relative variations in S-wave velocity.
