Assessing the relative threats posed by U. Rimmed by a crescent of older mountainous terrain, Yellowstone National Park has at its core the Quaternary Yellowstone Plateau, an undulating landscape At least volcanoes in 12 States and 2 territories have erupted in the past 12, years and have the potential to erupt again. Consequences of eruptions from U. Many aspects of our daily life are vulnerable to volcano hazards, The Yellowstone Plateau hosts an active volcanic system, with subterranean magma molten rock , boiling, pressurized waters, and a variety of active faults with significant earthquake hazards.
Within the next few decades, light-to-moderate earthquakes and steam explosions are certain to occur. Volcanic eruptions are less likely, but are ultimately Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. In the next few hundred years, Skip to main content. Search Search. Natural Hazards. Apply Filter. When will the next large earthquake occur in Yellowstone? Earthquakes cannot be predicted yet, but modern surveillance conducted with seismographs instruments that measure earthquake locations and magnitudes and Global Positioning System GPS instruments that measure slow ground movements help scientists understand the state of stress in the Earth's crust.
Those stresses could trigger earthquakes as What is a supervolcano? What is a supereruption? The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index VEI , meaning that at one point in time it erupted more than 1, cubic kilometers cubic miles of material.
Why are there so many earthquakes at Yellowstone? Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. Though we've been looking at Yellowstone for years, no one has yet identified "long-period LP events" commonly attributed to magma movement.
When was the last time Yellowstone erupted? How can you predict it, if it changes so much? Old Faithful Geyser has been analyzed for years by mathematicians, statisticians, and dedicated observers. During a short eruption, less water and heat are discharged; thus, they recharge in a short time. Longer eruptions mean more water and heat are discharged and they require more time to recharge.
In early morning, staff use information posted online by geyser enthusiasts who are in the basin or watching Old Faithful on the webcam outside regular visitor education center operating hours.
What else can I see at this geyser basin? The Upper Geyser Basin has geysers in one square mile, plus hundreds of hot springs. Five large geysers are predicted regularly by the education ranger staff. You can reach these and other features on boardwalks that loop through this basin. What will I see at Midway Geyser Basin? This geyser basin, six miles north of the Old Faithful area, is small but spectacular. Excelsior Geyser is a x foot 61 x m crater that constantly discharges more than 4, gallons 15, l of water per minute into the Firehole River.
Can I see mudpots in this area? Be sure to drive the Firehole Lake Drive, where you can walk past hot cascades, hot springs large and small, and view geysers such as White Dome and Great Fountain.
What animals can I see in this area? Hydrothermal basins provide important habitat for wildlife in the Old Faithful area.
Bison and elk live here year-round. In the winter, they take advantage of the warm ground and thin snow cover.
Both black and grizzly bears are seen, especially during the spring when winter-killed animals are available. In summer, yellow-bellied marmots are frequently seen in the rocks behind Grand Geyser and near Riverside Geyser. Thermophiles live in the runoff channels of hot springs and geysers, providing food for tiny black ephydrid flies. The flies, in turn, lay their eggs in salmon-colored clumps just above the water surface where they are then preyed upon by spiders. Killdeer also feast on the adult flies.

Old Faithful Historic District The district is historically significant because of its rustic architecture and its role in early development of visitor accommodations.
Places To Go Learn more about the amazing variety of destinations in Yellowstone. Learn more about how geysers, including Old Faithful, work. It is on the south section of the Grand Loop Road. Visiting Old Faithful in Winter. How high does Old Faithful erupt? It depends! Old Faithful eruptions can vary in height from feet.
The average is around feet. How long does an Old Faithful eruption last? Again, it depends. Old Faithful activity can last 1.
Unfortunately, there is no Old Faithful Geyser Schedule, you can use the predictions and then you have to watch. How hot is Old Faithful Geyser? Old Faithful has been measured at dregrees Fahrenheit at the vent and the steam has been measured above degrees Fahrenheit. How much water comes out of Old Faithful? Since the eruption lengths differ, so does the amount of water. The Park Service says the amount ranges from 3, gallons for a short duration of 1. What state is Old Faithful in? There are three entrances to Yellowstone in Montana and a little sliver of the park is in Idaho.
