Turkmenistan Gates of Hell
In 1971, near the village Darwaza in Turkmenistan Soviet geologists discovered a cluster of underground gas. Excavating and drilling, geologists had stumbled into an underground cavern (empty) causing the failed land and formed a large hole filled with gas. Drilling rig with all the equipment, vehicles fell into the resulting hole. Fortunately, the people in this incident were not injured. The livestock of gases did not go outside, and they decided to set it on fire. Geologists thought that the fire would go out after a few days, but made a mistake. Since 1971, the natural gas coming from the crater, continuously burns day and night. At that time, expectations were that the gas would burn out within days. However, set on fire in 1971, it is still burning! Four decades after the event. As of 2013, the hole is still burning.

«Nothing, which gets inside, can not get out. Any living creature is doomed. Once in the afterlife through these «doors», no one can escape. Buzzing and bursting with hot air crater, which diameter is 60 and a depth — 20 meters. The gas goes out of the ground, split into hundreds of different-sized burning torches. In some flares flames reach 10-15 meters in height.»

Village Darwaza was demolished in 2004. In 2010, the President of Turkmenistan Gurbanguly Berdimuhamedov visited Darwaza and said that the crater must be filled, or to be taken other measures to limit its impact on gas production in other fields area.
