6. The Door to Hell (Turkmenistan)
The Darvaza gas crater, also known as the Door to Hell or the Gates of Hell, is a unique place in the world. While digging for gas, the ground collapsed in a sinkhole and started leaking methane gas. Wanting to contain it, Soviet geologists set the gas on fire to prevent it from spreading. It has been burning continuously since 1971. In January 2022, President Berdymukhamedov publicly declared that a method to extinguish the fire needs to be found so that the effects on the environment and public health can be curbed.
