Yellowstone Caldera, also known as the Yellowstone Plateau Volcanic Field, is a Quaternary caldera complex and volcanic plateau spanning parts of Wyoming, Idaho, and Montana. It is driven by the Yellowstone hotspot and is largely within Yellowstone National Park.

Jan 3, 2025 · Yellowstone Caldera, enormous crater in the western-central portion of Yellowstone National Park, northwestern Wyoming, that was formed by a cataclysmic volcanic eruption some 640,000 years ago. It measures approximately 30 by 45 miles (50 by 70 km), covering a large area of the park.

Dec 6, 2024 · The Yellowstone Supervolcano is a massive volcanic system beneath the national park. It is one of the largest active volcanic systems in the world. The Yellowstone supervolcano has an enormous caldera, a large crater formed after a massive eruption empties the magma chamber beneath the surface.

Aug 31, 2021 · This eruption 2.1 million years ago—among the largest volcanic eruptions known to man—coated 5,790 square miles with ash, as far away as Missouri. The total volcanic material ejected is estimated to have been 6,000 times the volume of material ejected during the 1980 eruption of Mt. St. Helens, in Washington.

Aug 2, 2022 · Size of the Yellowstone Volcano: How Big is it? Yellowstone’s volcanic history begins as far back as 2.1 million years ago. ©iStock.com/ChrisB. Technically considered a supervolcano, the Yellowstone Volcano is roughly 30 by 45 miles in size.

The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana.

The Yellowstone Plateau volcanic field developed through three volcanic cycles that span two-million years. Two of the eruptions are considered some of the world's largest volcanic events. Yellowstone's youngest eruptions have been lava flows that remain confined to the caldera of present-day Yellowstone National Park.

Mar 27, 2024 · How Big is this Massive Volcano? The size of the Yellowstone volcano is almost too enormous to comprehend. It consists of two separate magma chambers; the first sits only 5 miles beneath the surface and is estimated to be about …

Nov 8, 2023 · Over the past 2.2 million years, the 17,000 km 2 (6,500 mi 2) Yellowstone Plateau has been shaped by explosive eruptions and profound collapse of the ground, enormously thick lava flows, uplift and extensive faulting, and the erosive power of flowing water and ice.

Jul 24, 2024 · Yellowstone is one of the largest known volcanoes in the world and the largest volcanic system in North America. The volcano is found above an intra-plate hot spot that has been feeding the magma chamber underneath Yellowstone for at least 2 million years.
