According to Wikipedia “In 1971, while drilling for natural gas in Darvaza, Turkmenistan, the ground on which the drilling rig was placed collapsed, leaving a large gaping hole exposed with a diameter of around 60 meters. To avoid poisonous gases coming out of the hole, it was decided to let the gases burn. As of 2008, gases in the underground cavern are still burning without interruption. Locals have named the cavern The Door to Hell.”
