The temperatures associated with a supervolcano vary greatly depending on location (e.g., in the magma chamber vs. an eruption's pyroclastic flow), but can reach up to 1,450 °C (2,640 °F) or higher deep underground.
At 80 kilometres beneath the Earth's surface it's about 1450 °C, say researchers – which, for a supervolcano, is only lukewarm.
The mounting evidence shows it's unlikely that volcanoes would wipe out humanity. "We can be confident of this because there have been two massive explosions while humans were present on Earth, and both of these were actually larger than Yellowstone's most recent cataclysmic eruption," the U.S.
Ask medieval historian Michael McCormick which year was the worst to be alive, and he's got an answer: "536." In that year, a mysterious fog plunged Europe, the Middle East, and parts of Asia into darkness, day and night—for 18 months.
What is a supervolcano? While the exact number isn't certain, there's thought to be around 20 supervolcanoes on Earth.
What are some other examples of supervolcanoes? Volcanoes that produced exceedingly voluminous pyroclastic eruptions and formed large calderas in the past 2 million years would include Yellowstone, Long Valley in eastern California, Toba in Indonesia, and Taupo in New Zealand.
Ever. What was the worst year to be alive on planet Earth? We make the case for 536 AD, which set off a cascade of catastrophes that is almost too horrible to imagine.
The Worst Times to Be Alive: History's Most Dangerous Decades
AD 536. A year of failed crops and of famine. A volcanic eruption had thrown a vast ash cloud into the stratosphere and according to accounts 'the sun became dark'.
The most recent period of dormancy has already lasted 70,000 years and may continue for thousands of additional years. “Yellowstone will reawaken someday to host more eruptions. But volcanoes like Yellowstone don't erupt without warning. We'd expect months of intense activity prior to any future eruption.”
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die. With prolonged contact, the amount of lava "coverage" and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
Prophetic passages in the Old Testament warn mankind of phenomena described very similarly to what we call volcanoes today. "You will be punished by the Lord of hosts with thunder and earthquake and great noise, with storm and tempest and the flame of devouring fire" (Isaiah 29:6).
1816, also known as the 'Year Without Summer,' 'Poverty Year,' and 'Eighteen Hundred and Froze to Death. ' The eruption of Mount Tambora in Indonesia in 1815 triggered a change in the global climate. The heavier material fell to the ground and the ocean's surface.
Yes. Encounters between aircraft and clouds of volcanic ash are a serious concern. Jet engines and other aircraft components are vulnerable to damage by fine, abrasive volcanic ash, which can drift in dangerous concentrations hundreds of miles downwind from an erupting volcano.
In addition, fluoride as high as 57 mg/L has been measured in Yellowstone thermal waters. Other nasty chemical constituents that are known to be elevated and may cause adverse health effects include antimony and mercury. So for a lot of reasons, stay away from thermal water. It is not good for your health!
The year 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F).
The 9 Worst Years in History to be Alive
But what really was the worst year to live through? The year 536 is a good contender. That's when a mysterious haze settled over most of the northern hemisphere and threw much of the world into an 18-month period of constant darkness. Around the world, temperatures plummeted and crops died.
But in the year 536, much of the world went dark for a full 18 months, as a mysterious fog rolled over Europe, the Middle East and parts of Asia. The fog blocked the sun during the day, causing temperatures to drop, crops to fail and people to die. It was, you might say, the literal Dark Age.
The Gothic War between the Byzantine Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 to 554 in the Italian peninsula, Dalmatia, Sardinia, Sicily, and Corsica. It was one of the last of the many Gothic wars against the Roman Empire.
The hot springs at Yellowstone National Park have injured or killed more people than "any other natural feature" there, according to the National Park Service. As you might imagine, the damage is usually caused by entering or falling into the boiling thermal waters.
Is a Yellowstone Eruption the End of Humanity? No, the eruption of the Yellowstone supervolcano isn't the end of the human race.
