The world’s only volcano that produces luminous blue fire is Kawah Ijen in Indonesia. The glowing flames are not lava—they’re caused by burning sulfuric gases igniting upon contact with oxygen at extremely high temperatures. The phenomenon is visible only at night. Important Details: • Only volcano with visible blue flames • Caused by ignited sulfur gases • Not molten lava • Visible only after dark • Result of extreme geothermal heat #EarthMysteries #VolcanoFacts #BlueFire #Geology #NaturalWonde

Stunning Electric-Blue Flames Erupt From Volcanoes Indonesia’s Kawah Ijen and other craters emit rivers of light from burning sulf. The Ijen volcano complex has some of the highest levels of sulfur in the world. This dense collection of the gas, when exposed to oxygen and lit by the molten hot lava burns blue. Unlike regular volcanoes whose bright red lava is visible in the day, Kawah Ijen’s blue burning flames can only be seen at night. #explore #indonesia #ijencrater #bluelava #bluefire #bluef
