Global seismographic networks (GSNs) emerged during the late nineteenth and early
twentieth centuries, facilitated by seminal international developments in theory, technology …

Geodynamic modeling and seismic studies have highlighted the possibility that a thin layer
of low seismic velocities, potentially molten, may sit atop the core‐mantle boundary but has …

Two continent-sized features in the deep mantle, the large low-velocity provinces (LLVPs),
influence Earth's supercontinent cycles, mantle plume generation, and geochemical budget …

Seismic tomography is the most abundant source of information about the internal structure
of the Earth at scales ranging from a few meters to thousands of kilometers. It constrains the …

Seismic imaging of the Earth's interior reveals plumes originating from relatively hot regions
of the lowermost mantle, surrounded by cooler material thought to be remnants of ancient …

We apply the adjoint method to efficiently calculate sensitivity kernels for long-period seismic
spectra with respect to structural and source parameters. Our approach is built around the …

Surface hotspot motions are approximately a factor of two faster in the Pacific than the Indo‐
Atlantic, and the Indo‐Atlantic large low shear velocity province (LLSVP) appears to be …

In this study, we inverted a large set of normal-mode centre-frequencies and quality
(attenuation) factors, including astronomic-geodetic data (mass, moment of inertia and tidal …

The core-mantle boundary (CMB) is the most extreme discontinuity in Earth's interior and
plays an important role in regulating planetary scale processes, including convection in both …

Seismic tomography allows us to image the interior of the Earth. In general, to determine the
nature of seismic anomalies, constraints on more than one seismic parameter are required …
