Sinking tectonic plate may've fuelled US supervolcano: Study

A US-based study has simulated that the supervolcano beneath Yellowstone National Park, US, could be fuelled by the tectonic plate that began sinking and melting beneath North America several million years ago. The study contradicts the previous belief that the volcano was powered by hot plumes from the Earth's mantle-core boundary. The park is known for its Grand Prismatic Spring.
