Darvaza Gas Crater-Turkmenistan 土库曼斯坦达尔瓦扎天然气坑洞 In 1971, geologists discovered a massive underground deposit of natural gas on this site. Whilst excavating the hole to tap the gas, thedrilling rig collapsed leaving a massive hole. To prevent poisonous gasses from escaping, the hole was allowed to burn. It continues to burn to this day and has done so without ceasing. 1971 年,地质学家发现该区域蕴藏着大量的地下天然气,在常年的开采过程中,由于不慎出现钻探环状坍塌,从而形成了一个非常大的坑洞。为了防止有毒气体溢出,土库曼斯坦政府允许对坑洞中的天然气进行燃烧,这个坑洞从白天到晚上一直处于熊熊烈火燃烧状态。因此,这处燃烧的天然气坑洞也被人们称为 “地狱之门”。
