Is blue lava hotter than regular lava?
At much higher temperatures, around 6000°C and up, black-body emission is distinctly blue, but this is much, much hotter than any magma can achieve naturally on Earth.
Why does Kawah Ijen have blue lava?
The crater of Kawah Ijen is the world’s largest blue flame area. Kawah Ijen has large amounts of sulfur deposits and fumaroles, and the high temperatures from the underground volcanic heat frequently combusts the sulfur on the surface of the volcano, producing the blue fires.
Is there purple lava?
The volcano contains large amounts of pure sulfur, which emits an icy violet color as it burns, filling the air with toxic fumes. The picture above was taken in a low lying field in Ethiopia. So what we’re seeing here is not actually blue lava, but normal, bright purple lava, surrounded by blue flames.
