自然灾害专家是科学家，他们确定了袭击地球的最极端灾难，并将遗留下来的证据准确地归类为一起。[编辑]??火山一支侦探队开始在全球范围内搜寻难以捉摸的火山大爆发，使中世纪的地球陷入深深的冰冻。当考古学家在伦敦发现一个由4000名男女儿童匆忙挖出的万人冢时，这个谜就开始了。最初，他们认为这是黑死病的灾祸，但是当他们与骨头约会时，还为时过早了一个世纪。那么什么杀死了这些家庭？那个年代的编年史描述了狂野的天气，破坏了庄稼，并在整个欧洲蔓延了饥荒。NOVA的专家团队正在寻找火山爆发的标志，该火山爆发必须足以将巨大的灰烬和硫酸云喷入大气层，从而使整个地球变冷。从格陵兰岛到南极洲，研究小组在冰层和土壤层中发现有说服力的“指纹”，直到最后，他们将罪魁祸首缩小到一个偏远的印尼岛屿上一个闷烧的火山口。大约750年前，这座火山的巨大爆炸将100万吨的岩石和灰烬喷入了大气。在全球范围内，它把夏天变成了冬天。如果今天再次发生这样的大灾难，会发生什么？??洪水在全世界，科学家们发现的古代洪水痕迹使最近的最严重的洪水灾害相形见war。是什么引发了这些灾难性洪水，它们又会再次袭击吗？在华盛顿州的海沟斯卡布兰群岛，高耸的草原被奇异而庞大的岩层所取代：房屋大小的巨石看似从天而降，悬崖峭壁被瀑布雕刻成尼亚加拉高两倍，而坑洼足以吞下汽车。就像犯罪现场的法医侦探一样，地质学家研究这些奇怪的特征，并重建比世界前十大河流总和还要强大的灾难性冰河世纪洪水。NOVA跟随他们的努力，发现了冰岛以及英吉利海峡海底的其他巨型超大洪水的地质指纹。那里，数十万年前，另一座洪水冲破了连接英法的陆桥，使英国首次成为一个岛屿。这些巨大的灾难在几小时之内席卷了地形和大洲，并且类似的力量被气候变化唤醒，对当今世界的山区社区构成了积极的威胁。??飓风2017年，毁灭性的飓风袭击了美国大陆和加勒比海岛屿。1780年的大飓风花了9天时间炸毁了整个加勒比海，至少造成20,000人丧生，这是有史以来任何一次天气事件中已知的最高死亡人数。是什么使这次超级风暴如此致命？为了重建史诗般的规模并调查造成这种灾难性破坏的原因，NOVA加入了历史学家和暴风侦探的行列，他们在目击者编年史，旧遗址和计算机模拟中寻找线索。他们的证据表明，一场真正可怕的300英里宽的风暴-风速可能超过每小时230英里，而25英尺的风暴潮摧毁了他们前进的道路。但是大飓风到底有多不寻常？潜入巴巴多斯和广场附近的污水坑Scientists who are experts in natural disasters identify the most extreme catastrophes to have hit the Earth and piece together exactly what happened from the evidence left in their wake.[edit] Volcanoes A team of volcano sleuths embark on a worldwide hunt for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. The mystery begins when archaeologists find a hastily dug mass grave of 4,000 men, women, and children in London. At first they assume it's a plague pit from the Black Death, but when they date the bones, they're a century too early. So what killed off these families? The chronicles of that time describe a run of wild weather that devastated crops and spread famine across Europe. NOVA's expert team looks for the signature of a volcanic eruption big enough to have blasted a huge cloud of ash and sulfuric acid into the atmosphere, which chilled the entire planet. From Greenland to Antarctica, the team finds telltale "fingerprints" in ice and soil layers until, finally, they narrow down the culprit to a smoldering crater on a remote Indonesian island. Nearly 750 years ago, this volcano's colossal explosion shot a million tons of rock and ash into the atmosphere. Across the globe, it turned summer into winter. What would happen if another such cataclysm struck again today?[edit] Floods All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world?s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours?and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.[edit] Hurricanes Devastating hurricanes struck the U.S. mainland and Caribbean islands in 2017. But they weren?t the first. The Great Hurricane of 1780 took nine days to blast its way across the Caribbean, killing at least 20,000?the highest known death toll of any single weather event in history. What made this superstorm so deadly? To reconstruct its epic scale and investigate what made it so devastating, NOVA joins historians and storm sleuths as they track down clues in eyewitness chronicles, old ruins, and computer simulations. Their evidence points to a truly terrifying, 300-mile-wide storm?with wind speeds probably exceeding 230 miles an hour and 25-feet storm surges that demolished everything in their path. But just how unusual was the Great Hurricane? Diving into sinkholes off Barbados and squirming into caves in the Yucatan, NOVA?s experts recover traces of tempests stretching back over more than 1,000 years. The picture they paint is disturbing: mega-hurricanes were not only more frequent in the past but are likely to strike again in our near future, as climate change warms the oceans and fuels more intense hurricanes.
