What is found underneath Yellowstone National Park?
Yellowstone is underlain by two magma bodies. The shallower one is composed of rhyolite (a high-silica rock type) and stretches from 5 km to about 17 km (3 to 10 mi) beneath the surface and is about 90 km (55 mi) long and about 40 km (25 mi) wide. The chamber is mostly solid, with only about 5-15% melt.
How far below Yellowstone is magma?
How large is the magma chamber that is currently under Yellowstone? The magma chamber is believed to be about 40 by 80 kilometers across, similar in size to the overlying Yellowstone caldera. The top of the chamber is about 8 km deep and the bottom is around 16 km deep.
What hotspot is under Yellowstone?
The hotspot currently lies under the Yellowstone Caldera. 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.
How deep is the Yellowstone hotspot?
400 miles deep University of Utah graphic. Detailed mapping shows the "hot spot" that fuels Yellowstone National Park's geothermal features is more than 400 miles deep, and might have been responsible for volcanic activity in Oregon, Washington, and Idaho 17 million years ago.
What’s under Old Faithful?
The Old Faithful geyser in Yellowstone national park is famed for its clockwork eruptions – every 90 minutes, on average. Now a secret chamber has been found in the rocks beneath the geyser, radically changing our understanding of how it erupts.
Is there a super volcano under Yellowstone?
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of Wyoming.
Is there lava under Yellowstone?
Since Yellowstone's last caldera-forming eruption 640,000 years ago, about 30 eruptions of rhyolitic lava flows have nearly filled the Yellowstone Caldera. Other flows of rhyolite and basalt (a more fluid variety of lava) also have been extruded outside the caldera.
What type of magma is under Yellowstone?
rhyolite It is well known that beneath Yellowstone caldera lies a large magma reservoir composed of mostly crystallized silicic magma called rhyolite.
Is the hotspot under Yellowstone moving?
The hotspot is stationary relative to the moving tectonic plates that make up Earth's surface. As the North American plate moves to the southwest over the hotspot, the center of volcanic activity therefore appears to be migrating to the northeast.
What is under Yellowstone National Park that is creating this super volcano?
Lurking beneath Yellowstone National Park is a reservoir of hot magma five miles deep, fed by a gigantic plume of molten rock welling up from hundreds of miles below. That heat is responsible for many of the park's famous geysers and hot springs.
When did Yellowstone last erupt?
70,000 years ago The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau, occurred 70,000 years ago.
Is Yellowstone hotspot still active?
Is Yellowstone's volcano still active? Yes. The park's many hydrothermal features attest to the heat still beneath this area. Earthquakes—700 to 3,000 per year— also reveal activity below ground.
How deep is the Old Faithful Geyser?
Based on the results of this work, Old Faithful's deeper plumbing system is approximately vertical between ~65 and 260 feet (20 and 80 meter) depth and is offset by 65 feet (20 meters) southwest of the geyser vent.

Is Yellowstone a ticking time bomb?
“But beneath this spectacular beauty lies a ticking timebomb. “Yellowstone is one of the largest volcanic systems on Earth and scientists call it a supervolcano because of the size of past explosions.”
What volcano could destroy the world?

How many miles down is magma?
This liquid layer around the core meets Earth's lower mantle about 1,800 miles (2,900 kilometers) below the surface.
Is magma rising under Yellowstone?
A new 3-D model shows the 45-mile-wide (72-kilometer-wide), 410-mile-deep (660-kilometer-deep) plume of hot, molten rock rising under Yellowstone's supervolcano.
When was the last eruption of the Yellowstone hotspot?
about 70,000 years ago When did the Yellowstone volcano last erupt? Approximately 174,000 years ago, creating what is now the West Thumb of Yellowstone Lake. There have been more than 60 smaller eruptions since then and the last of the 60–80 post-caldera lava flows was about 70,000 years ago.
How overdue is Yellowstone?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules.
Does Old Faithful still erupt?
The world's most famous geyser, Old Faithful in Yellowstone, currently erupts around 20 times a day. These eruptions are predicted with a 90 percent confidence rate, within a 10 minute variation, based on the duration and height of the previous eruption.
Is Yellowstone sitting on a volcano?
Is Yellowstone's volcano still active? Yes. The park's many hydrothermal features attest to the heat still beneath this area. Earthquakes—700 to 3,000 per year— also reveal activity below ground.
How hot is the water in Old Faithful?
204°F At only 45 feet (14 m) inside Old Faithful's throat, the water temperature is 244°F (117°C). Prior to an eruption, the water at the geyser's vent is 204°F (96°C)—several degrees hotter than the area's normal surface boiling point of 199°F (93°C).
Did Yellowstone erupt 65 million years ago?
Yellowstone has erupted at least three times before: 2.1 million years ago, 1.3 million years ago, and 630,000 years ago. Geologists think we're in the 'right' timeframe for another eruption.
What is the most violent supervolcano?
Hawaii's Kilauea volcano topped the list of most dangerous, followed by Mount St Helens and Mount Rainer in Washington. The Yellowstone supervolcano ranks third in the "high" threat category behind Mount Okmok and Iliamna Volcano, both in Alaska.
What volcano can wipe out the US?
The Yellowstone supervolcano is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.
Why are so many volcanoes erupting in 2021?

How deep do you have to dig to find lava?
The models showed that two factors — the ability of water vapor to bubble out of the magma, and the ability of the crust to expand to accommodate chamber growth — are the key factors constraining the depth of magma chambers, which are generally found between six and 10 kilometers deep.
What is below magma?
A magma chamber is an area beneath the Earth's surface where magma (molten rock) collects in a pool of molten rock. Magma forms in subduction zones where an oceanic plate is overridden by another crustal plate. The descending plate begins to melt and the molten rock collects in these underground chambers.
Is Yellowstone overdue for an eruption?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn't work out for the volcano to be “overdue” for an eruption.
