Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

Scientists have mapped how Earth’s deepest mantle is being deformed—and the results point to long-lost tectonic plates buried ...

In a groundbreaking studypublished in Seismological Research Letters, Australian National University (ANU) scientists have found that powerful winter storms in the North Atlantic Ocean send seismic ...

Scientists may have figured out the cause of some bizarre seismic waves echoing around the Earth's insides which have puzzled them for decades. These mysterious waves, known as PKP precursors, arrive ...

TEMPE, Ariz. — Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and ...

Deeply hidden in Earth's mantle there are two huge "islands" the size of a continent. New research from Utrecht University shows that these regions are not only hotter than the surrounding graveyard ...

At the center the Earth is a solid metal ball, a kind of “planet within a planet,” whose existence makes life on the surface possible, at least as we know it. How Earth’s inner core formed, grew and ...

A new study adds evidence to the idea that Earth's inner core is slowing its spin, though still rotating in the same direction as the planet. KATERYNA KON / SCIENCE PHOTO LIBRARY via Getty Images The ...

The study of earthquakes called Seismology, relies on the fact that different materials within the Earth react differently to stress. When a fault slips, energy radiates outward from the focus (the ...
