Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption. [ 89 ] [ 90 ] 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.
The third large eruption was about 0.6 Ma and created the Yellowstone Caldera. [4] This eruption produced 1,000 km2 of magma [7] through at least two volcanic vents. [4] The Yellowstone Caldera is above a continental hot spot, the Yellowstone mantle plume. [8] After the caldera was formed, there were rhyolitic lava flows between 160,000 and ...
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) are listed, especially those relating to the Yellowstone hotspot, Santorini caldera, and the Taupō Volcanic Zone. Active volcanoes such as Stromboli , Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear.
The most recent volcanic eruption occurred in Yellowstone approximately 650,000 years ago resulting in a 30- by 45-mile caldera, or basin. ... A timeline of last week's air disaster in Washington ...
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.

Scientists working in Yellowstone National Park say the supervolvcano underneath may blow sooner than thought and could wipe out life on the planet. Yellowstone supervolcano may be only decades ...
Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone Caldera since the last super eruption. The most recent lava flow occurred about 70,000 years ago, while the largest violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago.
