🔬 The Science Behind the Blue Fire
The blue flame comes from sulfuric gas that emerges from cracks in the volcano at extremely high temperatures (up to 600°C / 1,112°F).
When these gases meet the air and ignite, they create bright blue flames that can reach several meters high.
Unlike lava, this is not molten rock, but burning volcanic gas – making it very different from the usual “red fire” seen in other volcanoes.
