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.
The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...
Forecasting supervolcano eruptions is an inexact science, and the researchers end their paper by calling for continued monitoring of the area, not an evacuation.
What distinguishes a supervolcano from an ordinary volcano is the amount of volcanic material it has ejected during past eruptions — a reflection of the volcano’s explosive power.
Scientists discover that the volcano under Yellowstone is much bigger than previously thought.
It is the only known supervolcano located directly on the mid-ocean ridge. Grey's Landing Supereruption 8.72 Located in southern Idaho >2,800: One of 2 previously unknown Yellowstone hotspot Supereruptions; Largest Yellowstone eruption.

La Garita Caldera is a large caldera and extinct supervolcano in the San Juan volcanic field in the San Juan Mountains around the town of Creede in southwestern Colorado, United States. [1] It is west of La Garita, Colorado .
