  • The reason the sky is read in this painting is the same reason there's a small chance the entire North American continent might need to be evacuated soon.

  • I know that sounds crazy, and it is, but it's also true.

  • So buckle up, because today you're gonna learn about Super Volcanoes, volcanoes, air, one of those things, like great white sharks or quicksand, where you know it's dangerous, but you don't really care, because you're never gonna be near one.

  • So why is it your problem?

  • Well, some of these volcanoes air so big that if they ever decide to erupt, it's gonna be your problem no matter where you are for scale.

  • Let's talk about nuclear bombs for a second.

  • When the US bombed Hiroshima, the mushroom cloud that engulfed the city had a blast yield of 15 kilotons.

  • Nuclear weapons have gotten a lot bigger since then.

  • The Tzar Bomba, a Russian hydrogen bomb, had a blast yield 3000 times more powerful than that of Hiroshima.

  • That sounds big, right?

  • It's not.

  • The eruption from the Krakatau Volcano in Indonesia in 18 83 had the equivalent of 13,000 times the explosive yield of Hiroshima and four times the yield of the Tzar bomba.

  • This was obviously bad news for anyone on the island of the time.

  • If you somehow survived the explosion, the shockwaves, the poison gas and raining lava, then you had to deal with the fact that the island was slowly collapsing.

  • It's mostly underwater now.

  • It kind of makes you wonder if that's what happened to Atlantis.

  • If you were on the coastal town of a neighboring island like Java, Sumatra, then you'd be facing 130 ft high tsunami that likely would have wiped out your entire village.

  • Let's say you were sailing in the Indian Ocean 40 miles away.

  • Guess what sound wave that eventually hit you could have shattered your ear drums like it did for half of the crew of the H.

  • M s Norm Castle.

  • But if you were on the opposite side of the globe, you might have heard this as the pressure waves that came from that island in Indonesia circled the globe four times.

  • You would also notice, no matter where you were in the world, that the weather was colder than usual.

  • For the next year as a plume of volcanic ash covered the sky, creating a red hue that could be seen in this famous painting by Edvard Monk, Norway and many other paintings from that era.

  • Oh, did I not mention that?

  • Crack it out?

  • Isn't even a super volcano.

  • Yeah, it only measures is a six on the volcanic eruption index and the cut office.

  • You know what is one, though?

  • The volcano that sleeps under Yellowstone National Park, This guy is over 50 times larger than Krakatau.

  • And if it ever erupts, we're all gonna have to get off this continent really fast, though that might not even matter.

  • Since depending on their size, some super volcanoes have been theorized to have started a global Ice Ages.

  • Luckily, the chances of this happening anytime soon or close to zero.

  • According to the U.

  • S.

  • Geological Survey, the chances are actually one in 730,000, and it's only happened three times in the past two million years, so the chances were low.

  • I mean, they're not zero, but they're also, if it ever does, we're gonna have between a few weeks in a few years warning.

  • So I'm not gonna lose much sleep over this.

  • And I hope you don't either.

  • Okay.

  • Bye.
