Kawah Ijen’s Blue Fire Is Not Lava—Here’s the Real Cause

Kawah Ijen in East Java, Indonesia, is famous for its rare electric-blue fire. But the blue flames are not lava. They come from sulfur-rich volcanic gases escaping through cracks in the crater. When the hot gases meet oxygen, they ignite and create bright blue flames that can reach temperatures of up to 600°C. The flames are visible only at night because daylight makes the blue glow difficult to see. Kawah Ijen is also home to a highly acidic crater lake. This beautiful phenomenon is dangerous. Volcanic gases can be toxic, so visitors must follow official safety rules and never approach the crater without proper protection.
