On the other hand, according to Brian Wilcox of the Jet Propulsion Laboratory, such a project might trigger rather than prevent an eruption. [45] USGS, University of Utah and National Park Service scientists with the Yellowstone Volcano Observatory maintain that they "see no evidence that another such cataclysmic eruption will occur at Yellowstone in the foreseeable future. The Yellowstone Plateau is a broad region of high elevation directly above the hotspot, while the Snake River Plain has gradually subsided as that portion of the plate moved away from the hotspot. At Yellowstone and some other volcanoes, some scientists theorize that the earth's crust fractures and cracks in a concentric or ring-fracture pattern. Of the many calderas formed by the Yellowstone Hotspot, including the later Yellowstone Caldera, the Henry's Fork Caldera is the only one that is currently clearly visible. Only the islands southwest of Yellowstone are part of the North American continent. It is not intended to provide medical or other professional advice. New . Geology (2012) 40 (5): 479-480. Three extraordinarily large explosive eruptions in the past 2.1 million years each created a giant caldera within or west of Yellowstone National Park. Chapter 1: Plate Tectonics - The Story of Earth: An Observational Guide As North America drifted southwest over the hotspot, the volcanism progressed northeast, beginning in northern Nevada and southeast Oregon 16.5 million years ago and reaching Yellowstone National Park 2 million years ago. Future US, Inc. Full 7th Floor, 130 West 42nd Street, A deep mantle .

Watts, Ilya N. Bindeman and Axel K. Schmitt (2011) Petrology, Vol. [6], Over the past 16.5 million years or so, this hotspot has generated a succession of explosive eruptions and less violent floods of basaltic lava. GPS coordinates of Yellowstone hotspot, United States - latitude Yellow and orange ovals outline past caldera eruptions during the time periods indicated (orange calderas are the most recent). Below the picturesque geysers and rainbow-tinted hot springs of Yellowstone National Park lurks one of the most destructive volcanoes on Earth. The Heise volcanic field of eastern Idaho produced explosive caldera-forming eruptions which began 6.6 million years ago and lasted for more than 2 million years, sequentially producing four large-volume rhyolitic eruptions. Map scale reference is 60 latitude. Should the hotspot erupt again, scientists predict it will be another massive event. GPS Coordinates - Yellowstone National Park (U.S. National Park Service) The hotspot track runs from the Yellowstone National Park in NW Wyoming to the volcanic Modoc Plateau in NE California. [citation needed], The volcanic eruptions, as well as the continuing geothermal activity, are a result of a great plume of magma located below the caldera's surface. & Stock, J. Mammoth Hot Springs form in the northern part of the park where the hot water flows through limestone. The largest, most cataclysmic of these eruptions are called supereruptions. [12] Beneath more recent basalts are rhyolite lavas and ignimbrites that erupted as the lithosphere passed over the hotspot. UTM Zone 12: 4945010 N, 492295 E. Check the status and seasonal closing dates of park roads. Thankfully they are also less frequent. Water from rainfall and snowmelt seeps into the ground. [28], Volcanic and tectonic actions in the region cause between 1,000 and 2,000 measurable earthquakes annually. Bison hang around open areas near hydrothermal features. Used with permission from "Windows into the Earth, The Geologic Story of Yellowstone and Grand Teton National Park", Robert B. Smith and Lee J. Siegel, Oxford University Press, 2000. Since then the North American Plate has been moving west-southwest over the hotspot, so that a chain of explosive rhyolite volcanic centers (pink blobs) extends across the Snake River Plain to Yellowstone. Official websites use .gov Others argue the molten material that feeds hotspots is sourced from the mantle [85]. Occasionally, numerous earthquakes are detected in a relatively short period of time, an event known as an earthquake swarm. [41] From 2004 to 2008, the land surface within the caldera moved upward as much as 8 inches (20cm) at the White Lake GPS station. Harriman State Park is situated in the caldera. 85. How deep is the Yellowstone hotspot? The Yellowstone Hotspot surfaced 17 million years ago as massive outpourings of basalt lava in the Columbia PlateauSteens Basalt region. map coordinates ar e 41.364N, 121.0 19W . It created the eastern Snake River Plain through a succession of caldera forming eruptions. The classic definition of hotspots states they do not move, although recent evidence suggests that there may be exceptions [83]. Those fossils are preserved in sedimentary layers that were deposited from 54 to 6 million years ago. Meteorite Impact Origin of Yellowstone Hotspot - ResearchGate The resulting calderas include the Island Park Caldera, the Henry's Fork Caldera, and the Bruneau-Jarbidge caldera. 8.99Ma, McMullen Supereruption; VEI 8. Yellowstone National Park today lies directly over the hotspot. The Islands are located in the northern part of the Nazca plate, which is slowly drifting in a southeasterly direction at a rate of approximately 5cm per year. [47], A study published in GSA Today, the monthly news and science magazine of the Geological Society of America, identified three fault zones where future eruptions are most likely to be centered. The massive outpourings of basalt lava covered the Columbia Plateau and Steens Basalt regions. The water sometimes incorporates a lot of solid material on its way up, forming mud pots. The first three caldera-forming rhyolites Blacktail Tuff, Walcott Tuff and Conant Creek Tuff totaled at least 2250km3 of erupted magma. Surfacing of the hotspot was affected by subduction that is now manifest as the Cascadia Subduction Zone where the Juan de Fuca Plate descends beneath the edge of the continent. These Earth-shuddering blasts measure 8 or higher on the Volcanic Explosivity Index (VEI), which measures a volcanos relative explosivity by the height of its ash column and the volume of its leftover lava. A bow-wave or parabola-shaped zone of mountains (browns and tans) and earthquakes (red dots) surrounds the low elevations (greens) of the seismically quiet Snake River Plain. [27], An alternate theory to the mantle plume model was proposed in 2018. Thats when the thickness and composition of continental crust come into play. Geological Society of America. Ji, Y.

Rather, the water is rainfall and snowmelt that enters the ground from above. Discovery of two new super-eruptions from the Yellowstone hotspot track Geological Society of America. Fox, 61, describes Parkinson's disease as 'the gift that keeps on . The eruption distributed at least 280 cubic kilometers of ash known as the Mesa Falls Tuff, covering a region including all of Wyoming and most of Colorado, Nebraska, and Kansas. 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. [11] The Henry's Fork Caldera is nested inside of the Island Park Caldera and the calderas share a rim on the western side. Contrary to some media reports, Yellowstone is not 'overdue' for a supereruption. The latest large eruption at Yellowstone produced about 1,000 to 2,000 times the volume of material as the 1980 eruption of Mt. ScienceDaily, 7 January 2021. An official website of the United States government. Together these eruptions have helped create the eastern part of the Snake River Plain (to the west of Yellowstone) from a once-mountainous region. [1] 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. Glacial lake deposits in Hayden Valley form wetland meadows ideal for bison and other wildlife. Hagstrum, J. T. Antipodal hotspots and bipolar catastrophes: Were oceanic large-body impacts the cause? The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. A hotspot is like the hot wax rising in a lava lamp. [48], In 2017, NASA conducted a study to determine the feasibility of preventing the volcano from erupting.
