Chinese supercomputers help crack the mystery of Yellowstone's volcanic plumbing
A team led by Liu Lijun at the Institute of Geology and Geophysics, Chinese Academy of Sciences, has overturned a decades-old theory about how Yellowstone's magma system formed. Using 神威·太湖之光 (Sunway TaihuLight), one of China's most powerful supercomputers, they built a 3D numerical model spanning from surface to core-mantle boundary. The simulation revealed that tectonic forces tore the lithosphere apart first, creating pathways that magma later rose into—not the reverse, as previously believed. The researchers began this work in the United States but lacked adequate computing resources there; returning to China gave them access to the supercomputing power needed to run the massive simulations. The paper appeared in Science on April 10.
Yellowstone is the world's largest active volcanic system. Its eruptions are hundreds of times more powerful than Vesuvius, with ash capable of blanketing half the US. The long-standing debate centered on whether magma forced its own channels upward or exploited pre-existing fractures.
