Cratonic thinning, a phenomenon geologists think happened hundreds of millions of years ago, appears to be taking place far ...

Beneath the crust of North America, scientists have found that the deep roots of the continent are slowly dripping away in blobs of rock.

The deep oceans are far from flat. They feature ridges, trenches, seamounts, and valleys, creating a diverse and dramatic ...

Explore how North America is changing as its deep cratonic root thins and pieces are dripping into the Earth's mantle.

Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical ...

Leveraging fundamental-mode Rayleigh waves (20–150 s periods), the study applied azimuthal anisotropy tomography—a technique sensitive to directional variations in seismic wave speeds caused ...

Research in the last decade has concentrated on developing methods to focus seismic models derived from surface wave ... for exploiting ambient noise and earthquakes in surface wave tomography and ...
