Scientists' discovery of giant mantle structures reveals deep Earth mysteries beneath Africa and the Pacific Ocean. The post ...

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

Seismic tomography is a technique that uses seismic waves generated by earthquakes or artificial sources to create three-dimensional images of Earth’s interior. These waves travel at different ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction ...

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

Traditional seismic tomography methods, such as the travel time tomography, primarily rely on ray theory. While these methods can reveal the heterogeneous structure of the Earth’s interior ...

Wang, W., Chen, P., Dueker, K., Lee, E.-., Mu, D. & Keifer, I., (2020), Seismic evidence of glacial deposits inhibiting weathering of local bedrock at a snow ...

Drip-like features imaged in a seismic tomography model are consistent with extensive ongoing thinning of cratonic lithosphere beneath North America. As the early Earth solidified, gravitational ...

The integration of azimuthally varying surface-wave data with multi-scale tomography represents ... potential of high-resolution seismic imaging in earth sciences. The findings highlight the ...
