Sunken worlds under the Pacific? Highres models reveal workings of Earth's mantle
Jan 07, 2025
Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently than previously assumed. This indicates the presence of zones of rocks that are colder, or have a different composition, than the surrounding rocks. This finding challenges our current understanding of the Earth's plate tectonics—and presents the researchers with a major mystery.
