A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

Researchers mapped a pulsing mantle plume under Afar that channels molten rock upward, stretching Africa’s crust until it ...

They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

Earthquakes, volcanic eruptions, shifting tectonic plates—these are all signs that our planet is alive. But what is revealed deep inside Earth surprises laymen and scientists alike: Almost 3000 ...

In brief Geoscientists at ETH Zurich have solved a previously unexplained mystery using special laboratory experiments and computer simulations. They have demonstrated why earthquake waves change ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

This slowing of seismic waves led geologists to name the regions large low shear velocity provinces, or LLSVPs. Velocity loss in seismic waves suggested that these mantle zones were hotter than ...

Scientists have discovered structures that scatter seismic waves deep inside the mantle of Planet Earth everywhere and it is ...

Joanne Stephenson, a geophysicist at the Australian National University, clarified that the four primary layers of the Earth are the crust, the mantle, the outer core, and the inner core. Much of what ...

Waves from these quakes traveled through the core and up to North America, where they were recorded by EarthScope, a project that deployed portable seismic monitors across the U.S. between 2003 ...
