The discipline of seismology is based on observations of ground motion that are inherently
undersampled in space and time. Our basic understanding of earthquake processes and our …

Several sources of interest often generate both low‐frequency acoustic and seismic signals
due to energy propagation through the atmosphere and the solid Earth. Seismic and …

The asthenosphere plays a fundamental role in present-day plate tectonics as its low
viscosity controls how convection in the mantle below it is expressed at the Earth's surface …

The cratonic crust is the most long-lived tectonic unit on Earth. The longevity of Earth's
cratonic crust has been attributed to neutrally buoyant and mechanically strong lithospheric …

We present our third and final generation joint P and S global adjoint tomography (GLAD)
model, GLAD-M35, and quantify its uncertainty based on a low-rank approximation of the …

The origin of the Earth's lowest geoid, the Indian Ocean geoid low (IOGL) has been
controversial. The geoid predicted from present‐day tomography models has shown that …

Teleseismic tomography is a powerful tool to study the 3‐D structure of the upper mantle
beneath a local seismic network, but the robustness of its images has been challenged by …

Mid‐lithosphere discontinuities are seismic interfaces likely located within the lithospheric
mantle of stable cratons, which typically represent velocities decreasing with depth. The …

We present high‐resolution 3‐D tomographic models of isotropic P‐wave velocity (Vp),
azimuthal anisotropy, and radial anisotropy down to 1,300 km depth beneath the central and …

Using recently collected high‐resolution seismic data along a dense linear transect across
Ohio, West Virginia, and Virginia (called Mid‐Atlantic Geophysical Integrative Collaboration …
