The Lava Creek eruption of the Yellowstone Caldera, which occurred 640,000 years ago, [100] ejected approximately 1,000 cubic kilometres (240 cu mi) of rock, dust and volcanic ash into the atmosphere. It was Yellowstone's third and most recent caldera-forming eruption.
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).
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]
CHEYENNE, Wyo. (AP) — A surprise eruption in Yellowstone National Park shot steam, water and dark-colored rock and dirt high into the sky Tuesday and sent sightseers running for safety.
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.
