| 9 | There are three main ways a volcano can die, | 火山有三种主要的死亡方式 |
| 10 | and the first is if its supply of magma fizzles out. | 第一个是如果它供应的 岩浆纤维。 |
| 11 | The pushing together or pulling apart of | 一起推动或拆散 |
| 12 | tonic plates can cause magma to form. | 通心粉板可以使岩浆形成. |
| 13 | But when those plates fuse together, the magma forming | 但当这些板块融为一体时 岩浆就会形成 |
| 14 | activity stops, snuffing out the volcano. | 活动停止, 吸出火山。 |
| 15 | 波兰的Kaczawski山和Foothills有一个完整的国民 | |
| 16 | park devoted to volcanoes that suffered this fate. | 公园致力于火山 遭受了这个命运。 |
| 17 | Locals call it the Land of Extinct Volcanoes. | 当地人称之为"灭绝火山之地". |
| 18 | The second way a volcano can die is if it gets dragged away from its magma supply. | 火山的第二个死法是 如果它从岩浆供应中被拖走 |
| 19 | Sometimes, weird conditions in specific places can melt the mantle, sending up a plume of | 有时,特定地方的怪异条件会融化地幔,发出一股羽毛 |
| 20 | crust and can birth a volcano. | 地壳可以生出火山 |
| 21 | The hot spot itself doesn't ever move, but the Earth's crust above | 热点本身从未移动过 但上面的地壳 |
| 22 | it does, so the volcano will eventually leave its magma supply behind. | 因此火山最终会留下岩浆补给 |
| 23 | But since the hot spot itself | 但因为热点本身 |
| 24 | is still there, when one volcano dies in this way, a new one might form next to it, and then a new | 当一个火山以这种方式死亡时, 新的火山可能会形成在它的旁边, 然后一个新的火山 |
| 25 | one forms next to that, and so on. | 一种形式 旁边,等等。 |
| 26 | The Hawaiian Islands, for instance, are the newest volcanoes | 例如,夏威夷群岛是最新火山 |
| 27 | formed by a hot spot that has left a trail of dead volcanoes that stretches all the way to Russia. | 形成于一个热点 留下了一条通往俄罗斯的死火山的痕迹 |
| 28 | The third way a volcano can die is if it gets clogged. | 第三个死法是如果火山被堵塞的话 |
| 29 | Like, if conditions in the mantle change | 譬如,如果地幔的条件改变 |
| 30 | and the magma flow slows down, the magma that's already in the volcano's vents can cool, hardening | 岩浆流减慢 火山喷口中的岩浆可以冷却 变硬 |
| 31 | into a giant plug. | 进入一个巨大的插头。 |
| 32 | Fifty million years later, that plug might be all that's left of the volcano. | 5千万年后,这个插头 可能就是火山留下的 |
| 33 | Or, if the volcano's vents somehow get damaged, the magma might not be able to escape. | 或者,如果火山的喷口不知何故受损,岩浆可能无法逃脱. |
| 34 | In these | 在这些 |
| 35 | cases, the remaining magma will often find its way to a different spot nearby, where it can escape. | 其余的岩浆往往会找到通往附近不同地点的路,在那里可以逃脱。 |
| 36 | That's likely what happened when, in a spectacular eruption, the largest ever actually, | 这很可能是当, 在一次巨大的喷发, 有史以来最大的实际, |
| 37 | a volcano called Toba clogged itself. | 一座叫托巴的火山自封了 |
| 38 | Evidence suggests that the magma from its chamber got | 有证据表明 其舱内的岩浆 |
| 39 | rerouted to nearby Cinnabon, which is still active today. | 改道至附近的钦那邦,今天仍在活动. |
| 40 | Of course, it's really, really hard to tell | 当然,这真的,真的很难说 |
| 41 | exactly what's going on underneath a volcano, so we're not always sure what has happened to a | 火山下面究竟发生了什么 所以我们并不总是知道发生了什么 |
| 42 | volcano. | 火山喷发 |
| 43 | In fact, sometimes it's hard to tell whether a volcano is actually dead. | 事实上,有时很难判断火山是否真的死了. |
| 44 | Uderwunko, | 乌德文科, |
| 45 | in Bolivia, hasn't erupted in 250,000 years, so scientists assumed it was long gone. | 在玻利维亚,已经有25万年没有爆发了 所以科学家们认为它早就消失了 |
| 46 | But recently, | 不过最近 |
| 47 | it started rumbling again, suggesting the possibility of future volcanic activity. | 它又开始隆起 暗示未来火山活动的可能性 |
| 48 | It turns out that Uderwunko, and other quiet volcanoes like it, might not be dead after all. | 结果发现,乌德文科和其他像它一样安静的火山 可能不会死 |
| 49 | Instead, they could be taking magnificently long naps. | 相反,他们可能睡了很长的觉。 |
