Its diameter is 69 m and its depth is 30 m . The gas crater is located near the village of Derweze, also known as Darvaza. It is in the middle of the Karakum Desert, about 260 kilometres north of Ashgabat, the capital of Turkmenistan. The gas reserve found here is one of the largest in the world. The name “Door to Hell” was given to the field by the locals,  it looks like an entrance to the underworld- a huge gap with flame tongues tearing away day and night.
