Nyiragongo山在2002年1月在刚果民主共和国爆发时，似乎是一场灾难。熔岩冲入山坡，倒入附近的基伍湖。许多人死亡，戈马市的大部分地区被摧毁。实际上，当地人是幸运的。如果喷发扩散到基伍湖下面的许多火山断层之一，它可能会释放出所有自然现象中最可怕的现象之一-湖泊倾覆。窒息而死该湖倾覆现象于1984年首先在喀麦隆的莫农湖发生。37人突然无声地神秘死亡。出现了一系列奇异的理论：化学武器的秘密测试，未知恐怖分子的大屠杀；没有一个是真的。研究灾难的科学家认为，这与湖泊本身有关，1986年，在对莫农灾难的研究尚未公开之前，一切再次发生了。同样在喀麦隆的尼约斯湖的悲剧在世界各地成为头条新闻，当时有近1,800人在湖周围的房屋中睡觉，使他们的睡眠令人窒息。经过调查的科学家小组得出结论，被困在湖底的二氧化碳突然上升到地表，杀死了25公里范围内的所有生物。他们称其理论为湖泊倾覆。减轻压力最终，科学家们意识到地下的二氧化碳涌入将二氧化碳泵入湖泊，如果不采取任何行动，整个悲剧将会重演。他们在湖中间安装了一个非凡的喷泉，以帮助气体扩散。即使是这样，尼约斯（Nyos）灾难促使人们对非洲和印度尼西亚的深湖进行了调查，以了解还有哪些湖面可能发生倾覆。除了卢旺达的基伍湖（Lake Kivu）以外，其他所有人似乎都很安全。基伍湖是非洲最大，最深的湖泊之一，其海岸周围有200万人居住。它也充满了二氧化碳，尽管它尚未被致命的气体所饱和。唯一可以触发瓦斯释放的是巨大的地质事件。令人担忧的是，基伍湖正坐在地震区，周围是活火山，包括尼拉贡戈山。如果在湖下发生喷发或地震，那么这种影响可能会将数百万吨的窒息性气体释放到周围地区。在找到解决方案之前，When Mount Nyiragongo erupted in the Democratic Republic of Congo in January 2002 it seemed like a disaster. Molten lava plunged down the hillside and poured into nearby Lake Kivu. Many died, and much of the city of Goma was destroyed. In fact, the local people were lucky. Had the eruption spread to one of the many volcanic faults under Lake Kivu, it could have unleashed one of the most terrifying of all natural phenomena - lake overturn.Death by suffocationThe phenomenon of lake overturn first struck in 1984 at Lake Monoun, in Cameroon. 37 people mysteriously died, suddenly and silently. A bizarre array of theories sprang up - secret testing of chemical weapons, a massacre by unknown terrorists; none really made sense. The scientists who looked into the disaster believed it had to be something to do with the lake itself, but they could not be absolutely sure.In 1986, before research into the Monoun disaster was made public, it all happened again. The tragedy of Lake Nyos, also in Cameroon, made headlines around the world when almost 1,800 people sleeping in houses around the lake suffocated in their sleep. The team of scientists that went to investigate concluded that carbon dioxide, trapped at the bottom of the lake, had suddenly risen to the surface, killing everything within 25km. They called their theory lake overturn.Releasing the pressureEventually the scientists came to realise that carbon dioxide springs underground were pumping carbon dioxide into the lake and that the whole tragedy would be repeated if nothing was done. They installed an extraordinary fountain in the middle of the lake to help the gas disperse. Even so, the level of carbon dioxide in the waters remains a concern.The Nyos disaster promoted a survey of deep lakes in Africa and Indonesia to see where else lake overturn could happen. All seem to be safe, except one - Lake Kivu, in Rwanda. Lake Kivu is one of the largest and deepest lakes in Africa and two million people live around its shore. It is also filling up with carbon dioxide, although it's not yet saturated with the deadly gas. The only thing that could trigger a gas release would be a massive geological event. Worryingly, Lake Kivu is sitting in an earthquake zone and surrounded by active volcanoes, including Mount Nyiragongo. If an eruption or an earthquake was to happen under the lake, then the effect could release millions of tons of asphyxiating gas into the surrounding areas. Until a solution is found, millions of lives could be at risk.
