The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...
Yellowstone National Park, known for erupting geysers like Old Faithful, is home to one of earth’s largest volcanic systems, with the capacity to wreak havoc on an entire continent — and ...
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
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
The Yellowstone Supervolcano also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [86] 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.
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. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.
Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
