Global horizontal S-wave seismic velocity anomaly maps for different upper-mantle depths highlighting the variable base topography of the surface plates with seismically fast, deep continental roots and cratons reaching far down into the mantle. Shown is the average of two upper-mantle seismic tomography models, SL2013sv (Schaeffer & Lebedev, 2013) and 3D2016_09Sv (Debayle et al., 2016). The Scientific colour map ‘batlow‘ is used to represent data accurately and to all readers.
