This work shows that the electrical characteristics of the asthenosphere, the conductive part of the upper mantle, are directly connected to the amount of carbonate in the layer.

Iceland is one of the most active volcanic regions in the world, but its seismic nature is part of a much broader geological history.

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

Scientists have long wondered why the asthenosphere, the lower part of Earth's mantle, is relatively weak compared to the crust, and seismic waves are providing some clues.

Nozomu Takeuchi and colleagues at the University of Tokyo, Kobe University, and the Japan Agency for Marine–Earth Science and Technology, analysed the attenuation of seismic waves as they propagated ...

The upper layer of Earth's mantle, labeled here as the asthenosphere, is hotter than previously thought, a new study finds. (Image credit: vectortatu/Shutterstock) ...

A large crack, stretching several kilometres, made a sudden appearance recently in south-western Kenya.

Additionally, they note, "At greater depths, the lithosphere-asthenosphere boundary (LAB) represents a first-order structural discontinuity that accommodates differential motion between the ...
