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. [4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
Volcanoes that have produced explosive VEI-8 eruptions, often called supervolcanoes in the media. Such eruptions release a tephra volume of at least 1,000 km 3 (240 cu mi) with annihilating long-term effects on the surrounding area and devastating short-term effects on global climate, leaving profound effects on the climate for years to come.
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time.

Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment. “The western part of the Yellowstone ...
Scientists discover that the volcano under Yellowstone is much bigger than previously thought.
The Yellowstone Supervolcano also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [76] 174,000 years ago. Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption.
A long-quiet yet massive super volcano, dubbed the "Long Valley Caldera," has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so.
