Kawah Ijen on Java Island has blue flames that shoot up to five metres high when sulfur ignites at 600°C as it emerges from the crater. At night, the burning sulfur drips down the slopes, creating the illusion of blue lava. Local workers mine sulfur from the volcano's acidic crater lake.
Have you ever heard of a blue lava volcano? Java Island is home to one of the world's most unique volcanoes. Let me explain. Kawah Ijen volcano is famous around the world for its blue fires, most acidic crater lake, and labor-intensive sulfur mining. The sulfur from the volcano can reach temperatures of up to 600°C as it breaks the surface, causing it to ignite and erupt into blue flames. These flames rise up to 5 meters and then slowly melt down the volcano's face, creating the illusion that blue lava is flowing down the volcano. This breathtaking display is best seen at night, although not as frequently. This unusual phenomenon can also be seen at Kilauea in Hawaii, Yellowstone National Park, and Dalol Mountain in Ethiopia.
