Summary

Story summary

A study by the Chinese Academy of Sciences finds Yellowstone's volcanic system is driven by tectonic forces, not a mantle plume.
The study in Science presents a model showing magma originates from shallow mantle and moves through a tectonically controlled plumbing system.
The model improves understanding of how magma travels toward eruptions.
Yellowstone's last major eruption occurred about 630,000 years ago, and the findings could improve predictions of future hazards.
