💙🌋 Blue lava… wait, what?! This surreal glow in Indonesia isn’t molten rock, but burning sulfur gas. At volcanoes like Ijen, sulfur-rich gases ignite as they escape at extreme temperatures, creating electric-blue flows that look like lava at night — one of Earth’s most jaw-dropping volcanic illusions. #BlueLava #Geology #GeologyPage #Volcanology #indonesia | Geology Page

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
