Yanar Dag

Yanar Dag is a natural gas fire which blazes continuously on a hillside on the Absheron Peninsula on the Caspian Sea near Baku, the capital of Azerbaijan (a country which itself is known as "the Land of Fire"). Flames jet into the air 3 metres (9.8 ft) from a thin, porous sandstone layer. 
Unlike mud volcanoes, the Yanar Dag flame burns fairly steadily, as it involves a steady seep of gas from the subsurface.
