The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...
The Yellowstone Supervolcano also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [64] 174,000 years ago. Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption.
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.
The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.
This eruption produced more than 280 km2 of magma [7] and was nested within a portion of a larger caldera, the Huckleberry Ridge Caldera. [4] 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 most recent volcanic eruption occurred in Yellowstone approximately 650,000 years ago resulting in a 30- by 45-mile caldera, or basin. The heat powering the volcanic eruptions still fuels the ...
This eruption is considered the climactic event of Yellowstone's third volcanic cycle. The Lava Creek Tuff covers an area of more than 7,500 km 2 (2,900 sq mi) centered around the caldera and has an estimated magma volume of 1,000 km 3 (240 cu mi).
Things are getting hotter than a Dutton family feud. Yellowstone National Park, known for erupting geysers like Old Faithful, is home to one of earth’s largest volcanic systems, with the ...
