The findings provide a new perspective on the processes that sustain supervolcanoes, which are capable of producing eruptions with far-reaching impacts on climate, ecosystems, and human societies. Understanding the role of mantle wind and magma mush systems could improve predictions of volcanic activity and help mitigate risks associated with supereruptions. Yellowstone, a key site for studying supervolcanoes, has experienced two supereruptions in the past 2.1 million years, underscoring the importance of this research.
