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

我知道這聽起來很瘋狂，也確實如此，但這也是事實。

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.

所以繫好安全帶，因為今天你要學習的是超級火山，火山，空氣，這些東西中的一種，就像大白鯊或流沙，你知道它的危險性，但你並不在意，因為你永遠不會靠近它。

So why is it your problem?

那為什麼是你的問題？

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.

嗯，有些火山的空氣如此之大，如果他們決定爆發，它會是你的問題，無論你在哪裡的規模。

Let's talk about nuclear bombs for a second.

讓我們來談談核彈吧。

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

當美國轟炸廣島時，吞噬城市的蘑菇雲的爆炸產量為15千噸。

Nuclear weapons have gotten a lot bigger since then.

從那時起，核武器就變大了許多。

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

俄國的氫彈 "Tzar Bomba "的爆炸威力是廣島的3000倍。

That sounds big, right?

這聽起來很大，對吧？

It's not.

不是這樣的

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.

1883年印度尼西亞喀拉陶火山的噴發，其爆炸量相當於廣島爆炸量的13000倍，是沙皇炸彈產量的4倍。

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

這對當時島上的任何人來說，顯然都是一個壞消息。

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.

如果你以某種方式在爆炸、衝擊波、毒氣和熔岩雨中活了下來，那麼你就必須面對島嶼正在慢慢坍塌的事實。

It's mostly underwater now.

現在大部分都在水下。

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

這讓你不禁懷疑亞特蘭蒂斯是不是也發生了這樣的事情。

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.

如果你是在鄰近島嶼如爪哇島、蘇門答臘島的沿海城市，那麼你將面臨130英尺高的海嘯，很可能會把你的整個村莊都消滅掉。

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

假設你在40英里外的印度洋上航行。

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.

猜猜看，最終打在你身上的聲波，可能會像打在H號上一半的船員身上一樣，震碎你的耳鼓。

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.

但如果你在地球的另一端，你可能會聽到這句話，因為來自印尼那個島嶼的壓力波繞地球四圈。

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

你也會發現，無論你在世界的哪個角落，天氣都比平時冷。

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.

在接下來的一年裡，由於火山灰的羽翼覆蓋了天空，形成了紅色的色調，在挪威愛德華-蒙克的這幅著名的畫作中，以及其他許多那個時代的畫作中都可以看到。

Oh, did I not mention that?

哦，我沒說嗎？

Crack it out?

破解它？

Isn't even a super volcano.

是不是連一座超級火山都沒有。

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

是啊，它的衡量標準只是火山噴發指數和切割辦公室的6分。

You know what is one, though?

你知道什麼是一個，雖然？

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

沉睡在黃石國家公園下的火山，這傢伙比喀拉喀託大50多倍。

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

如果它爆發了，我們都得儘快離開這片大陸，雖然這可能並不重要。

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

由於根據它們的大小，一些超級火山被理論上認為已經開始了全球冰河世紀。

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

幸運的是，這種情況短時間內發生的機率或接近於零。

According to the U.

據美國。

S.

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.

地質調查局，這個機率其實是73萬分之一，而且在過去200萬年裡只發生過三次，所以機率很低。

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.

我的意思是，他們不是零， 但他們也，如果它曾經做， 我們要去有幾個星期之間 在幾年的警告。

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

所以我不會因為這個而失眠的。

And I hope you don't either.

我希望你也不要。

Okay.

好吧，我知道了

Bye.
