New simulations of the asthenosphere find that convective cycling and pressure-driven flow can sometimes cause Earth's most fluid layer of mantle to move even faster than the tectonic plates that ride ...

Precise determination of the thickness of the continental lithosphere and the magnitude and depth range of the velocity gradient at its base has proved challenging with existing seismic techniques.

New research from the University of Houston reevaluates the role of the asthenosphere in tectonic plate movement. According to the new study published in Nature Communications by scientists from the ...

Researchers in Japan have used measurements of the aftershocks of the 2011 Tohoku earthquake to gain insight into the dynamics of the Earth’s crust and upper mantle. Nozomu Takeuchi and colleagues at ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...
