A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

Scientists have known since the 1960s that mantle plumes stay in place for a very long time while the Earth's plates move over them. Every time the plate shifts a bit, the mantle plume produces a ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Indian scientists have uncovered the possible cause behind the Indian Ocean Geoid Low (IOGL), the lowest geoid anomaly on ...

This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath the central Pacific showing the relationship between seismically-slow "plumes" and channels imaged in the study.

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...
