Ample warning of supervolcano eruptions likely, experts say

Scientists have now made the best computational modeling yet of mantle plumes, hypothesized, mushroom-shaped upwellings of hot rock from the deep Earth. They plumes are hypothesized to form within the thermal boundary layer at the base of the mantle and are thought to carry heat from Earth's core that generates a volcano's magma.
