Yellowstone, located in Wyoming, USA, is the most famous supervolcano and also has the potential to be the most powerful.
The Yellowstone Caldera supervolcano last erupted 700,000 years ago but experts say it should blow every one million years or so.
Is Yellowstone the largest volcano in the world?
The Yellowstone supervolcano — thousands of times more powerful than a regular volcano — has only had three truly enormous eruptions in history. One occurred 2.1 million years ago, one 1.3 million years ago, and one 664,000 years ago.
Where is the largest volcano in the world?
Mauna Loa is runner-up to Tamu Massif for the world’s biggest volcano. Also an enormous ocean volcano, Mauna Loa is one of five volcanoes on the Big Island of Hawaii. Its most recent eruption was in 1984, and Mauna Loa has spewed lava 33 times in the past 170 years.
How many Super volcanoes are there and where are they?
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.
Where are the 7 super volcanoes located?

When did Yellowstone caldera last erupt?
Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption. The most recent lava flow occurred about 70,000 years ago, while a violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago.
How many years is Yellowstone overdue?
Three super-eruptions at Yellowstone appear to have occurred on a 600,000-700,000 year cycle starting 2.1 million years ago. The most recent took place 640,000 years ago – suggesting Yellowstone is overdue for an eruption.
