Yellowstone's Magma on the Move

Yellowstone's magma reservoirs are shifting northeast, warns a 2024 USGS study, suggesting a new hotspot for future eruptions. This area houses around 440 cubic kilometers of rhyolitic magma, rejuvenated by ascending basaltic flows. Despite 82 small earthquakes last December and minor subsidence, current activity remains low. Researchers using magnetotellurics emphasize vigilance, recalling Yellowstone’s two supereruptions 2.1M and 640k years ago. No imminent threats, but Mother Nature likes to keep us on our toes.
