Seismic and geophysical studies reveal that the Hawaiian hotspot features pronounced internal heterogeneities, including distinct low-velocity anomalies along the chain, localized asthenospheric variations, and structural complexity at the core-mantle boundary.
The retrieved papers provide strong seismic and geochemical evidence detailing the internal structure of the Hawaiian hotspot and swell, showing specific variations such as plume conduits, asthenospheric low-velocity layers, and core-mantle boundary features. No papers refute the claim.
