A deep, rhythmic pulse has been found surging like a heartbeat deep under Africa. At the Afar triple junction under Ethiopia, ...

The new model of the Earth's mantle and crust from Sandia National Laboratories and Los Alamos National Laboratory is called Sandia-Los Alamos 3D, or SALSA3D.

The model shows mantle plumes (where the hot rock flows) starting at the bottom of the core-to-mantle boundary and climbing to the top, where they connect to volcanic hotspots in the Earth's crust.

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

deformation of the lithosphere (crust and uppermost mantle) and seismic tomography (a technique that uses seismic waves to generate 3D models of Earth's interior). They identified two stages of ...

Feng explains that these models incorporate information from seismic waves, gravity measurements, magnetic fields, and other geophysical observations to create detailed 3D representations of the ...

"The stony asteroid would have opened up a hole probably almost the thickness of Earth's crust, almost 30 km [18 miles] deep, and on the order of 80 to 100 km [50 to 62 miles] wide." ...

Some areas of continental crust have maintained long-term stability from the beginning of Earth's history, ... (a technique that uses seismic waves to generate 3D models of Earth's interior). ...
