the yellowstone caldera is the volcanic caldera located in yellowstone national park in the united states sometimes referred to as the yellowstone supervolcano the caldera is located in the northwest corner of wyoming in which the vast majority of the park is contained the major features of the caldera measure about 34 miles 55 km by 45 miles 72 kmlast eruption70000 years ago magmatic 1350 bc 200 years explosive hydrothermal ongoing nonexplosive hydrothermalyellowstone lies over a hotspot where light hot molten mantle rock rises towards the surface while the yellowstone hotspot is now under the yellowstone plateau it previously helped create the eastern snake river plain to the west of yellowstone through a series of huge volcanic eruptions although the hotspot039s apparent motion is to the east-northeast the north american plate is really moving west-southwest over the stationary hotspot in the earth039s mantleover the past 17 million years or so this hotspot has generated a succession of violent eruptions and less violent floods of basaltic lava together these eruptions have helped create the eastern part of the snake river plain from a once-mountainous region at least a dozen of these eruptions were so massive that they are classified as supereruptions volcanic eruptions sometimes empty their stores of magma so swiftly that they cause the overlying land to collapse into the emptied magma chamber forming a geographic depression called a caldera calderas formed from explosive supereruptions can be as wide and deep as mid- to large-sized lakes and can be responsible for destroying broad swaths of mountain rangesthe oldest identified caldera remnant straddles the border near mcdermitt nevada-oregon although there are volcaniclastic piles and arcuate faults that define caldera complexes more than 60 km 37 mi in diameter in the carmacks group of southwest-central yukon canada which is interpreted to have formed 70 million years ago by the yellowstone hotspot progressively younger caldera remnants most grouped in several overlapping volcanic fields extend from the nevada-oregon border through the eastern snake river plain and terminate in the yellowstone plateau one such caldera the bruneau-jarbidge caldera in southern idaho was formed between 10 and 12 million years ago and the event dropped ash to a depth of one foot 3048 cm 1000 miles 1600 km away in northeastern nebraska and killed large herds of rhinoceros camel and other animals at ashfall fossil beds state historical park within the past 17 million years 142 or more caldera-forming eruptions have occurred from the yellowstone hotspotthe loosely defined term 039supervolcano039 has been used to describe volcanic fields that produce exceptionally large volcanic eruptions thus defined the yellowstone supervolcano is the volcanic field which produced the latest three supereruptions from the yellowstone hotspot the three super eruptions occurred 21 million 13 million and 640000 years ago forming the island park caldera the henry039s fork caldera and yellowstone calderas respectivelythe island park caldera supereruption 21 million years ago which produced the huckleberry ridge tuff was the largest and produced 2500 times as much ash as the 1980 mount st helens eruption the next biggest supereruption formed the yellowstone caldera 640000 years ago and produced the lava creek tuff the henry039s fork caldera 12 million years ago produced the smaller mesa falls tuff but is the only caldera from the srp-y hotspot that is plainly visible todaynon-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the yellowstone caldera since the last supereruption the most recent lava flow occurred about 70000 years ago while a violent eruption excavated the west thumb of lake yellowstone around 150000 years ago smaller steam explosions occur as well an explosion 13800 years ago left a 5 kilometer diameter crater at mary bay on the edge of yellowstone lake located in the center of the calderacurrently volcanic activity is exhibited via numerous geothermal vents scattered throughout the region including the famous old faithful geyser plus recorded ground swelling indicating ongoing inflation of the underlying magma chamberthe volcanic eruptions as well as the continuing geothermal activity are a result of a great cove of magma located below the caldera039s surface the magma in this cove contains gases that are kept dissolved only by the immense pressure that the magma is under if the pressure is released to a sufficient degree by some geological shift then some of the gases bubble out and cause the magma to expand this can cause a runaway reaction if the expansion results in further relief of pressure for example by blowing crust material off the top of the chamber the result is a very big gas explosion
