Deep inside Earth, far below the crust and mantle we learn about in school, scientists are mapping strange, continent-sized structures that appear to shape everything from volcanic hotspots to the ...

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity provinces, or LLVPs, stretch beneath Africa and the Pacific. They are so ...

Colossal volcanic eruptions like the kind that may have obliterated the dinosaurs more than 65 million years ago are caused by mantle plumes that rise from shifting underground mountains deep within ...

A new study shows that giant ore deposits are tightly distributed above where rigid rocks that comprise the nuclei of ancient continents begin to thin, far below the surface (white areas). Redder ...

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

The illustration shows a cutaway revealing the interior of early Earth with a hot, melted layer above the boundary between the core and mantle. Scientists think some material from the core leaked into ...

Scientists discover hidden "ghost plume" that is so powerful that it is physically warping the internal layers of the planet ...

Deep beneath your feet, far beyond where any drill can reach, something strange is hiding. Two continent-sized blobs of rock sit just above Earth’s core, hot, dense and stubbornly different from ...

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