Fig. 2From: Waveform inversion for 3-D S-velocity structure of D′′ beneath the Northern Pacific: possible evidence for a remnant slab and a passive plumeResults of the inversion (CG6) for the 3-D shear wave velocity structure in the lowermost 400 km of the mantle beneath the Northern Pacific and Alaska for each 50 km depth slice. PREM (Dziewonski and Anderson 1981) is used as the reference modelBack to article page
