Abstract
A drastic change in plate tectonics and mantle convection occurred around 50 Ma as exemplified by the prominent Hawaiian–Emperor Bend. Both an abrupt Pacific Plate motion change and a change in mantle plume dynamics have been proposed to account for the Hawaiian–Emperor Bend, but debates surround the relative contribution of the two mechanisms. Here we build kinematic plate reconstructions and high-resolution global dynamic models to quantify the amount of Pacific Plate motion change. We find Izanagi Plate subduction, followed by demise of the Izanagi–Pacific Ridge and Izu–Bonin–Mariana subduction initiation alone, is incapable of causing a sudden change in plate motion, challenging the conventional hypothesis on the mechanisms of Pacific Plate motion change. Instead, Palaeocene slab pull from Kronotsky intraoceanic subduction in the northern Pacific exerts a northward pull on the Pacific Plate, while its Eocene demise leads to a sudden 30–35° change in plate motion, accounting for about half of the Hawaiian–Emperor Bend. We suggest the Pacific Plate motion change and hotspot drift due to plume dynamics could have contributed nearly equally to the formation of the Hawaiian–Emperor Bend. Such a scenario is consistent with available constraints from global plate circuits, palaeomagnetic data and geodynamic models.

Extended Data Fig. 4 Model with plume-head push.
Model with plume-head push. a, b and c show the thermal structures of the forward CitcomS model with plume-head. a and b show a cross section (see the location of the cross section in the inserted panel) and a map view (at 200 km) of the initial plume head at 120 Ma. c represents the thermal structure of the forward CitcomS model at 50 Ma. d represents the thermal structure of the CitcomS model at 50 Ma without imposing the plume head at 120 Ma. The difference between c and d represents the contribution from the plume head, which is highlighted with the red circle in c. The difference is superimposed on the thermal structure of the forward model at 50 Ma based on the traditional model, to test the effect of plume-head push, which is shown in e. In e, the green, orange, black and red arrows represent the geodynamically predicted velocities without plume-head push, the geodynamically predicted velocities with plume-head push, the reconstructed velocities from ref. 9 and the reconstructed velocities from ref. 10, respectively.

Extended Data Fig. 8 Computations of the Hawaiian-Emperor Seamount hotspot tracks and plume motion.
Computations of the Hawaiian-Emperor Seamount hotspot tracks and plume motion. We combine the Pacific Plate motion change and the hotspot drift path to reconstruct the Hawaiian-Emperor Seamount chain. For the Pacific Plate motion, we use the preferred geodynamic Kronotsky-SUB track that combines the Pacific Plate motion from Müller et al.9 after 47 Ma and from the geodynamic models that incorporates the Kronotsky subduction before 47 Ma. The residual hotspot drift path in Fig. 4 is used in a, while the hotspot drift in Hassan et al.5 is used in b. To first order, the two hotspot drift paths are similar.
Extended Data Fig. 9 Geodynamically predicted horizontal velocity in the vicinity of Hawaiian plume as a function of depth for different models.
Geodynamically predicted horizontal velocity in the vicinity of Hawaiian plume as a function of depth for different models. For each depth, the velocities are averaged over the region from 190°E to 220°E and from 10°N to 35°N. The blue arrows represent the averaged velocities at 60 Ma, the red arrows at 50 Ma and the black arrows at 47 Ma.
