The continental crust is unique to the Earth in the solar system, and controversies remain
regarding its origin, accretion and reworking of continents. The plate tectonics theory has …

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

Our understanding of subsurface processes suffers from a profound observation bias:
seismometers are sparse and clustered on continents. A new seismic recording approach …

This paper presents a new model of the shear velocity structure of the crust and uppermost
mantle beneath the contiguous US The model is based on more than a decade of USArray …

USArray, a pioneering project for the dense acquisition of earthquake data, provides a semi-
uniform sampling of the seismic wavefield beneath its footprint and greatly advances the …

The Yellowstone supervolcano is one of the largest active continental silicic volcanic fields
in the world. An understanding of its properties is key to enhancing our knowledge of …

Seismic structure beneath the contiguous US was imaged with multimode receiver function
stacking and inversion of Rayleigh wave dispersion and ellipticity measurements. Crust …

To better constrain the temperature structure in the upper mantle, we jointly invert seismic
surface wave velocities and basalt thermobarometry. New measurements of the water …

Subduction of young seafloors straddling mid-ocean ridges (MOR) is an inevitable
consequence of plate tectonics. Surprisingly, this process correlates globally with prolonged …

The Yellowstone hotspot, located in North America, is an intraplate source of magmatism the
cause of which is hotly debated. Some argue that a deep mantle plume sourced at the base …
