Yellowstone's volcano may be fueled in a very different way than we thought
Yahoo • • science
Key Points:
- New research suggests Yellowstone's volcanic activity is driven by shifts in Earth's crust rather than a deep mantle plume, challenging previous assumptions about its magma source.
- The study used a 3D model incorporating tectonic plate movements and mantle structure, finding that tectonic forces stretch and tilt the lithosphere beneath Yellowstone, pulling magma upwards.
- This tectonic-driven model explains the magma migration path observed beneath Yellowstone and could improve predictions of future volcanic activity.
- Understanding these mechanisms is crucial as Yellowstone's volcanic system will eventually interact with colder, thicker crust to the east, potentially altering its behavior.
- The research approach may also help scientists better understand other major volcanic systems worldwide, including Toba, Taupo, and volcanoes in northeastern China.
