Drilling Down to Open Up New Understanding of Earth’s Continents

by Christopher A. Scholz, Anders Noren, Lisa Park Boush, Brett M. Carpenter and Russell Callahan 27 March 202627 March 2026

Scientists have drilled into Earth’s crust for decades to understand natural hazards, past climates, energy resources, and more. They’ve only scratched the surface of what we can learn.

Two maps of Earth show areas highlighted in red and blue. In the image called “nonelliptical geoid,” the darkest blue area is in the Indian Ocean. In the image labeled “nonhydrostatic geoid,” the darkest blue area is over Antarctica.

What do BLOBs Have to Do with Earth’s Magnetic Field? A Lot, It Turns Out

by Bill Morris 5 March 20265 March 2026

Enormous provinces of superheated mantle exert a powerful influence over our planet’s magnetic field, researchers have discovered.

Scientists Create the First Map of Deep Earthquakes Beneath Continents

by Larissa G. Capella 5 March 20265 March 2026

Scientists once thought Earth’s continental mantle was too weak for earthquakes. A new global map of 459 deep tremors suggests otherwise.

Kyanite Exsolution Reveals Ultra-Deep Subduction of Continents

by Jun Tsuchiya and Sujoy Ghosh 23 January 202622 January 2026

Laboratory experiments provide the first experimental evidence that continental rocks can be subducted to depths greater than 300 kilometers and return to the surface.

From Mantle Flow to River Flow: Shaping Earth’s Surface from Within

by Fabio A. Capitanio 20 November 202519 November 2025

The convection of the Earth’s mantle shapes its surface, carving fault networks into the lithosphere that can guide the course of rivers.

New 3D Model Reveals Geophysical Structures Beneath Britain

by Nathaniel Scharping 10 October 202510 October 2025

Using magnetotelluric data to identify subsurface electrically conductive and resistive areas, scientists can identify underground features and predict how space weather may affect infrastructure.

Blame It on the BLOBs

by Bill Morris 15 August 202514 August 2025

For decades, scientists have suspected that large volcanic eruptions have their origins in two mysterious massive regions at the base of our planet’s mantle. Now, it’s been statistically proven.

Finding the Gap: Seismology Offers Slab Window Insights

Sarah Stanley, Science Writer by Sarah Stanley 15 August 202514 August 2025

Studying slow tremors has helped researchers home in on the youngest part of the Chile Triple Junction’s gap between subducting plates, which offers a window to the mantle.
