The D'' layer of the mantle flows in a solid state due to post-perovskite alignment, which accelerates seismic waves by 7%.

Seismic evidence revealed that these fortresses, the size of a continent, were tougher and older than the dead ocean plates around the mantle.

Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size ...

A bold new theory reimagines the NAA as a "Rayleigh–Taylor instability"—a geological term for when heavy, cold rock begins to ...

Mantle plumes are a portion of abnormally hot mantle (around 1,450°C) or unusual composition of the mantle (or both) below Earth's surface.

New research suggests that mysterious "BLOBS" under the Earth could actually be driving volcanic activity.

This plume melts the Earth’s mantle and forms magma, which over long periods results in the formation of an island chain or breaks up continents.

By simulating the movement of two continent-sized Big Lower-Mantle Basal Structures, or BLOBs, researchers may have uncovered the magmatic engine behind Earth’s most devastating eruptions.

A seismologist from Seattle discussed recent volcanic activity across the United States. Here's what you should know.

Connection between the deep mantle and Earth’s surface showing the relationship between BLOBS, mantle plumes and giant volcanic eruptions – not drawn to scale (The Conversation) ...

Finally, volcanoes can also be located in the middle of plates associated with mantle plumes, which are concentrated regions where magma rises from the deep mantle to shallow depths.
