The Hawaiian-Emperor hotspot track has a prominent bend, which has served as the basis for the theory that the Hawaiian hotspot, fixed in the deep mantle, traced a change in plate motion. However, paleomagnetic and radiometric age data from samples recovered by ocean drilling define an age-progressive paleolatitude history, indicating that the Emperor Seamount trend was principally formed by the rapid motion (over 40 millimeters per year) of the Hawaiian hotspot plume during Late Cretaceous to…

The Bent Hawaiian-Emperor Hotspot Track: Inheriting the Mantle Wind
TLDR
Inverse modeling suggests that although deep flow near the core-mantle boundary may have played a role in the Hawaiian-Emperor bend, capture of a plume by a ridge, followed by changes in sub-Pacific mantle flow, can better explain the observations.
MOTION AND GEOCHEMICAL VARIABILITY OF THE HAWAIIAN HOTSPOT 1
The bend in the Hawaiian-Emperor volcanic chain is an often-cited example of a change in plate motion with respect to a stationary hotspot. Growing evidence, however, suggests that the bend might…
Pacific plate motion change caused the Hawaiian-Emperor Bend
TLDR
It is demonstrated that southward hotspot drift cannot be a sole or dominant mechanism for formation of the Hawaiian-Emperor Bend (HEB), which cannot be explained without invoking a prominent change in the direction of Pacific plate motion around 47 Ma.
50-Ma Initiation of Hawaiian-Emperor Bend Records Major Change in Pacific Plate Motion
TLDR
New ages for volcanoes of the central and southern Emperor chain define large changes in volcanic migration rate with little associated change in the chain's trend, which suggests that the Hawaiian-Emperor bend did not form by slowing of the Hawaiian hot spot.
Paleomagnetic modeling of seamounts near the Hawaiian–Emperor bend
On the motion of Hawaii and other mantle plumes
Hotspot motion caused the Hawaiian-Emperor Bend and LLSVPs are not fixed
TLDR
New paleomagnetic data are presented to show that the great bend in the Hawaiian-Emperor seamount chain can be attributed to mantle plume motion and that LLSVPs are mobile.
Louisville Seamount Trail: implications for geodynamic mantle flow models and the geochemical evolution of primary hotspots
The Louisville Seamount Trail is a 4300 km long volcanic chain that has been built in the past 80 m.y. as the Pacific plate moved over a persistent mantle melting anomaly or hotspot. Because of its…
A rapid burst in hotspot motion through the interaction of tectonics and deep mantle flow
TLDR
Palaeogeographically constrained numerical models of thermochemical convection are presented and it is demonstrated that flow in the deep lower mantle under the north Pacific was anomalously vigorous between 100 million years ago and 50 millions years ago as a consequence of long-lasting subduction systems, unlike those in the south Pacific.

Mesozoic plate-motion history below the northeast Pacific Ocean from seismic images of the subducted Farallon slab
TLDR
A three-dimensional spherical computer model of mantle convection is used to show that seismic images of the subducted Farallon plate provide strong evidence for a Mesozoic period of low-angle subduction under North America.
Isotopic evidence for Late Cretaceous plume–ridge interaction at the Hawaiian hotspot
TLDR
As the rising mantle plume encountered the hot, low-viscosity asthenosphere and hot, thin lithosphere near the spreading centre, it appears to have entrained enough of the isotopically depleted upper mantle to overwhelm the chemical characteristics of the plume itself, and the Hawaiian hotspot joins the growing list of hotspots that have interacted with a rift early in their history.
