The loosely defined term "supervolcano" has been used to describe volcanic fields that produce exceptionally large volcanic eruptions. Thus defined, the Yellowstone Supervolcano is the volcanic field that produced the latest three supereruptions from the Yellowstone hotspot; it also produced one additional smaller eruption, thereby creating the ...
Lava Creek Tuff. The Lava Creek Tuff is a voluminous sheet of ash-flow tuff located in Wyoming, Montana and Idaho, United States. It was created during the Lava Creek eruption around 630,000 years ago, which led to the formation of the Yellowstone Caldera. This eruption is considered the climactic event of Yellowstone's third volcanic cycle.
The most recent eruption of Steamboat Geyser occurred on July 15th, 2024 at 3:08 PM. This was the 167th eruption since it re-activated in early 2018. [10] In 2019 the 48th eruption occurred on December 26. That set a new record for the most eruptions within a calendar year. The calendar year 2020 also saw 48 eruptions, tying the record set in ...
The world's largest active geyser has erupted three times in the past six weeks at Yellowstone National Park.
Map of Yellowstone Volcano ash beds. The plateau developed through three volcanic cycles spanning two million years that included some of the world's largest known eruptions. The eruption of the >2,500 km 2 (970 sq mi) Huckleberry Ridge Tuff about 2 million years ago created the more than 75 km (47 mi) long Island Park Caldera.
Mascarene Islands were formed in a series of undersea volcanic eruptions 8–10 Ma, as the African plate drifted over the Réunion hotspot. Yellowstone hotspot, Twin Fall volcanic field, Idaho; 8.6 to 10 Ma. [65] Yellowstone hotspot, Grey's Landing Supereruption, Idaho; 8.72 Ma, 2,800 cubic kilometers (672 cu mi) of Grey's Landing Ignimbrite. [66]
The time between the last three cataclysmic eruptions in the Yellowstone area has ranged from 600,000 to 800,000 years; however, the small number of such climactic eruptions cannot be used to make an accurate prediction for future volcanic events. [90]
44°26′N 110°40′W / 44.43°N 110.67°W / 44.43; -110.67. The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession ...
