What are the global effects of a supervolcano eruption?

Potential global impact of a supervolcano If a supervolcano was to erupt there would be a global catastrophe. It would kill around 100,000 people instantly and make most of North America uninhabitable as huge amounts of ash and dust would be thrown into the atmosphere.

Can a supervolcano destroy the world?

Roughly every 100,000 years, there’s a supervolcano explosion somewhere in the world, the consequences of which can be fatal. If the volcano below Yellowstone National Park were to erupt, it would result in worldwide hunger and a volcanic winter (the cooling of the lower atmosphere).

What happened to the sun in 536?

“For the sun gave forth its light without brightness, like the moon, during the whole year,” wrote Byzantine historian Procopius. Temperatures in the summer of 536 fell 1.5°C to 2.5°C, initiating the coldest decade in the past 2300 years.

What would really happen if Yellowstone erupts?

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. It’d be a huge disaster.

Would Yellowstone cause an ice age?

“Sunlight would be blocked out and the ash particulates would take several years to fall out from our atmosphere. “The sheer volume of the ash generated would block out sunlight, creating a ‘twilight/dusk’ that’d last for years. “This would also end global warming and be the start of an ice age.

Why is year 536 the worst in history?

In 2018, medieval scholar Michael McCormick nominated 536 as “the worst year to be alive” because of the extreme weather events probably caused by a volcanic eruption early in the year, causing average temperatures in Europe and China to decline and resulting in crop failures and famine for well over a year.
