Massive Deep-Earth Structures Influence Earth's Magnetic Field
Researchers from the University of Liverpool and the University of Leeds, including Professor Andy Biggin and the DEEP research group, have discovered two massive, ultrahot rock formations located at the base of Earth's mantle beneath Africa and the Pacific Ocean. These structures influence the planet's magnetic field by affecting the flow of liquid iron in the Earth's outer core. The formations have been shaping Earth's magnetic field for millions of years. The findings were published in a study released on February 3, 2026. This research highlights the connection between deep mantle structures and the long-term behavior of Earth's magnetic field.
