Yellowstone Supervolcano – 10% Chance of Erupting within 80 Years

There is a 10% chance the Yellowstone Supervolcano could blow sometime in the next 80 years; and while that’s a pretty slim chance, the event would devastate humanity.

Experts at the European Science Foundation (ESF) are warning that instances of volcanic eruptions are the highest in 300 years. They fear that a major eruption could kill millions of people and wreak havoc on the planet.

In the spring of 2015, scientists said they had discovered that the Yellowstone Supervolcano was much bigger than they thought. A newly found reservoir of magma and hot rock that lies 12-28 miles beneath the volcano turned out to be 11,000 cubic miles (46,000 cubic kilometers), “which is about the volume of Long Island with 9 miles of hot rock piled on it, or 300 Lake Tahoes.” [1]

A report – Extreme Geo-hazards: Reducing the Disaster Risk and Increasing Resilience – warns that not only is the caldera more expansive than previously thought, governments around the world would be left nearly helpless should Yellowstone erupt.

The Yellowstone Supervolcano is thought to have last erupted some 640,000 years ago. When it did, it probably covered much of North America in 1.2 m-2 m of ash, close to 6 feet. ESF scientists say supervolcanoes, like the one at Yellowstone, pose more of a danger to human survival than asteroids, earthquakes, nuclear war and global warning.

Yellowstone is not the only supervolcano that poses a threat to the planet. There’s also Mount Vesuvius in Campagnia, Italy, and Popocatépetl near Mexico City. Scientists put the risk of eruption at the other sites in the next 80 years at 5-10%. [1]

If any of them were to erupt, it would kill millions of people and destroy the earth’s atmosphere with ash and toxins “beyond the imagination of anything man’s activity and global warming could do over 1,000 years.”

The report says:

“Although in the last few decades earthquakes have been the main cause of fatalities and damage, the main global risk is large volcanic eruptions that are less frequent but far more impactful than the largest earthquakes.

Due to their far-reaching effects on climate, food security, transportation, and supply chains, these events have the potential to trigger global disaster and catastrophe.

The cost of response and the ability to respond to these events is beyond the financial and political capabilities of any individual country.”
