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).

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.

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.

2024年12月4日 · The Phlegraean Fields, now considered one massive supervolcano, are beginning to stir, making the scientific community uneasy. These volcanic fields, nestled just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide worldwide.

2023年11月1日 · Both Campi Flegrei and the Long Valley Caldera are known as supervolcanoes, a term used to describe a volcano that at one time has erupted more than 240 cubic miles of material.

2023年6月9日 · A long-slumbering "supervolcano" in Italy is getting closer to a potential eruption for the first time since 1538, a new study warns — and the consequences could be catastrophic.

2025年2月17日 · Supervolcanoes are what people mean when they say that Wyoming has a terrible secret located beneath Yellowstone Park, whose caldera last erupted roughly 630,000 years ago and was 1,000 times more potent than the 1980 St. Helens eruption that laid waste to hundreds of square miles.
