First use of NanoSIMS ion probe measurements to understand volcanic cycles at Yellowstone

(Geological Society of America) Super-eruptions are not the only type of eruption to be considered when evaluating hazards at volcanoes with protracted eruption histories, such as the Yellowstone (Wyoming), Long Valley (California), and Valles (New Mexico) calderas. There have been more than 23 effusive eruptions of rhyolite lava at Yellowstone since the last caldera-forming eruption approximately 640,000 years ago, all of similar or greater magnitude than the largest volcanic eruptions of the 2...
