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.

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.

There are more than 1,000 active volcanoes dotted around our planet, but only a select few have produced unimaginably colossal eruptions, earning themselves the title of supervolcano. Find out more about supervolcanoes - what they are, what their eruptions are like and how they impact our planet. How do we measure volcanic eruptions?

2019年3月19日 · Learn how supervolcanoes form, where supervolcanoes are located, and how their destructive capabilities can make way for new life. How dangerous are supervolcanoes? Get the facts. Though...

2022年4月2日 · There are about 20 known supervolcanoes on Earth – including Lake Toba in Indonesia, Lake Taupo in New Zealand, and the somewhat smaller Phlegraean Fields near Naples, Italy. Super-eruptions occur rarely – only once every 100,000 years on average.

2017年7月1日 · Supervolcanoes are volcanic centers that have experienced the eruptions ranked at level 8 on the Volcanic Explosivity Index (VEI). The VEI is a scale that describes the size of volcanic eruptions based on magnitude and intensity.

2024年2月11日 · Supervolcanoes represent Earth’s most explosive volcanic eruptions, described as apocalyptic or colossal. They are ultraplinian with an explosivity index 8 on a scale of 0 to 8 and form eruptive columns that reach the stratosphere.

The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning the measured deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles).

What Is a Supervolcano? A volcano that erupts and throws magma and rocky particles over an area greater than 240 cubic miles (1000 cubic kilometers) is considered a supervolcano. These massive eruptions dwarf typical volcanic eruptions.
