A Giant Volcano Could End Human Life on Earth as We Know It 超级火山，人类灭绝的最大威胁？ If you're planning to visit Yellowstone National Park this Labor Day weekend, I have good news: It is very, very, very unlikely that the supervolcano beneath it will erupt while you're there. 如果你打算在这个劳动节周末去黄石国家公园，我有个好消息：你在公园期间，公园下面的超级火山喷发的可能性非常非常小。 The Yellowstone supervolcano — an 8 out of 8 on the Volcanic Explosivity Index — has erupted three times over the past 2.1 million years, most recently 640,000 years ago. A Yellowstone eruption would be like nothing humanity has ever experienced. 黄石超级火山在过去210万年里喷发过三次，最近一次是在64万年前。人类历史上还没有经历过黄石火山喷发。 |
