Subduction zones occur where one tectonic plate dives under another. New computer modeling by Magali Billen, professor of earth and planetary sciences at UC Davis, shows why earthquakes on these sinking plates cluster at certain depths and could give insight into processes deep in the Earth.

Researchers developed a technique that allows them to study the atomic arrangements of liquid silicates at the extreme conditions found in the core-mantle boundary. This could lead to a better understanding of the Earth's early molten days, which could even extend to other rocky planets. Credit: Greg Stewart/SLAC National Accelerator Laboratory
