Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption. [ 101 ] [ 102 ] The most recent lava flow occurred about 70,000 years ago, while a violent eruption excavated the West Thumb of Lake Yellowstone 174,000 years ago.
Flat Landing Brook; VEI 8, A Supervolcanic eruption occurred 466 million years ago, as it erupted in one of the largest explosive volcanic eruptions known in Earth's history with a volume of ejecta at around 2,000–12,000 cubic kilometers (480–2,879 cu mi). The Phanerozoic eon begins 539 million years ago. [91]

Map of Yellowstone Volcano ash beds. The Yellowstone Plateau Volcanic Field began forming around 2 Ma (million years ago). [7] It has had over 110 different eruptions and has created mostly rhyolitic plains, with over 6000 km 3 of rhyolitic material formed. [7] Scientists have discovered three major eruptions that formed calderas.
