To compare, Mt. St. Helens' eruption in 1980 was a level 4. Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera.
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
An answer to this question would help to estimate how likely this volcano, and other large volcanoes and supervolcanoes, are to erupt, and what warning signs to look out for. [29] A February 2020 status report indicated that earth uplift around Pozzuoli continued at steady rates, with a maximum average of 0.7 cm per month since July 2017.
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. Numbers indicate millions of years before ...
Two long-dormant “supervolcanoes” on two separate continents appear to be stirring to life. Well, maybe. In recent months, more than a thousand minor earthquakes have rattled the area around ...
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.
6: Laki: 1783–1784: 6: 14 cubic kilometres of lava: an estimated 120 million tons of sulfur dioxide were emitted, produced a Volcanic winter, 1783, on the North Hemisphere. [28] Long Island (Papua New Guinea), northeast of New Guinea: 1660 ±20: 6: 30 km 3 (7.2 cu mi) of tephra [2] Kolumbo, Santorini, Greece: 1650, Sep 27: 6: 60 km 3 (14.4 cu ...
