Detailed explanation-1: -The Yellowstone supervolcano, located in northwestern Wyoming in Yellowstone National Park, is one of the largest volcanoes in the world. It’s erupted multiple times over the past 2.1 million years, including three massive eruptions that smothered the surrounding landscape in ash.
Detailed explanation-2: -The Yellowstone supervolcano last erupted about 640, 000 years ago. A sleeping giant is nestled in the western part of the United States. Though it stirs occasionally, it has not risen from slumber in nearly 70, 000 years.
Detailed explanation-3: -The biggest supervolcano on Earth was discovered in 2013: the Tamu Massif, with a 4 km height and a 640 km width, a submarine shield volcano located in the Pacific Ocean, east of Japan.
Detailed explanation-4: -No, Yellowstone does not contain the biggest supervolcano in the world. The largest supervolcano is the Wah Wah Springs caldera in Utah, which once exploded with over 30 times the pyroclastic debris as Yellowstone’s largest eruption.
