Supervolcano - Wikipedia
Supervolcanoes occur when magma in the mantle rises into the crust but is unable to break through it. Pressure builds in a large and growing magma pool until the crust is unable to contain the pressure and ruptures.

2024年8月21日 · These massive natural wonders have the power to alter the planet's climate and trigger global catastrophes. Unlike your everyday volcano, super volcanoes have eruptions of epic proportions, releasing thousands of cubic kilometers of magma in a single blast.
What is a supervolcano? What is a supereruption? - USGS.gov
The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material. In the early 2000s, the term “supereruption” began being used as a catchy way to describe VEI 8 eruptions.

Category:Supervolcanoes - Wikipedia
Supervolcanoes are large volcanoes that have had an eruption with a volcanic explosivity index (VEI) of 8, the largest recorded value on the index. This means the volume of deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles).
