What happens if Yellowstone blows?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. In fact, it’s even possible that Yellowstone might never have an eruption that large again.
What is the largest supervolcano in the world?
World’s largest “supervolcano” is even bigger than previously thought. Seismologists have discovered a massive magma reservoir beneath the Yellowstone supervolcano in Wyoming, US, that suggests its volcanic system could be more than 5.6 times larger than was previously thought.

And while Mount Vesuvius’ destruction of Pompeii in 79 A.D. is one of the most famous volcanic eruptions, its death toll of 2,000 was only a fraction of Tambora’s.
Is Yellowstone the largest volcano?
The Island Park Caldera supereruption (2.1 million years ago), which produced the Huckleberry Ridge Tuff, was the largest, and produced 2,500 times as much ash as the 1980 Mount St. Helens eruption. The next biggest supereruption formed the Yellowstone Caldera (~ 630,000 years ago) and produced the Lava Creek Tuff.

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.
How many times has Yellowstone erupted?
History of Yellowstone’s Supervolcano. The Yellowstone area has seen tremendous volcanic activity in its past. 3 giant eruptions have occurred between 2.1 million and 640,000 years ago.
Is Yellowstone active dormant or extinct?
Yellowstone is another “dormant” volcano, yet the level of constant unrest under Yellowstone might make it “active” by my definition. A truly dormant volcano by the USGS standards might be Clear Lake in California, which hasn’t erupted in likely close to 10,000 years. Extinct: It takes a lot to be an “extinct” volcano.
Is Long Valley a supervolcano?
The Long Valley Caldera is the depression formed from the supervolcano eruption 760,000 years ago, which ejected hot ash, lava and toxic gas. Fortunately, there is an extremely low likelihood of any supervolcano eruption occurring in any of our lifetimes.
What warning signs make volcanoes predictable?
“These signs may include very small earthquakes beneath the volcano, slight inflation, or swelling, of the volcano and increased emission of heat and gas from vents on the volcano,” said U.S. Geological Survey (USGS) Volcano Hazards Program coordinator John Eichelberger.
Is Krakatoa a supervolcano?
The eruption of Krakatoa, or Krakatau, in August 1883 was one of the most deadly volcanic eruptions of modern history. It is estimated that more than 36,000 people died. The island of Krakatau is in the Sunda Strait between Java and Sumatra. It is part of the Indonesian Island Arc.
What is the most dangerous volcano in the Pacific Ring of Fire?

What is the VEI scale?
The Volcanic Explosivity Index (VEI) is a relative measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982. The scale is open-ended with the largest volcanoes in history given magnitude 8.
What would happen if Taupo erupted?
There is only a very small chance the volcano that is now Lake Taupo will erupt, but researchers are planning for a worst case scenario in case it does. The Earthquake Commission said damage from the last time the volcano erupted – almost 1800 years ago – would be large enough to destroy the central North Island.
What’s the biggest volcano?
Tamu Massif dwarfs the largest active volcano on Earth, Mauna Loa in Hawaii, which measures about 2,000 square miles (5,200 square kilometers). Made of basalt, Tamu Massif is the oldest and largest feature of an oceanic plateau called the Shatsky Rise in the northwestern Pacific Ocean.

First, the Vesuvian eruption, consisting of a column of volcanic debris and hot gases ejected between 15 km (9.3 mi) and 30 km (19 mi) high into the stratosphere, lasted eighteen to twenty hours and produced a fall of pumice and ashes southward of the volcano that accumulated up to depths of 2.8 m (9.2 ft) at Pompeii.
