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 ...

A seismic mystery nearly 3,000 kilometers underground has finally been solved: researchers found that solid rock flows horizontally, aligning minerals and causing a shift in earthquake wave speeds.

Earth’s inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

The Mystery of the D” Layer The D” layer, located near the boundary between Earth’s mantle and core, has been a subject of scientific curiosity since the 1960s. Seismic waves behave oddly ...

The depths of the Earth still hold many surprises. A team of scientists has discovered that objects move horizontally in the Earth's mantle, nearly 1,864 miles (3,000 km) beneath our feet. This ...

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

As oil companies push for drilling on the Amazon coast, an underwater war silences the ocean’s most vocal creatures.

On March 28, 2025, a major earthquake with a moment magnitude (Mw) of 7.7 struck Mandalay, central Myanmar (referred to as ...
