In the day the Kawah Ijen looks like an ordinary volcano, in the night changes color and turns blue phosphorescent.
Kawah Ijen volcano, in the day when it erupts red fire flames seems an “ordinary volcano”. At night, however, the lava turns blue phosphorescent.
The blue color is due to the presence of sulfur, present in high quantities also at the liquid state. The sulfur passes through the volcanic vents reaching the surface of the volcano.
The blue, high flames, can reach 5 meters. A part of the gas condenses into liquid and ignites again.
Since National Geographic spoke about the blue volcano, tourists have increased. To reach the crater rim you have to walk two hours, plus another 45 minutes to the shore. Blue fire emerges from the cracks at temperatures up to 600° C. When the liquid sulfur passes through the vents and reaches the surface, it gives off a lethal gas for humans.
The lake on the summit of the volcano is the largest acid lake in the world. Its waters feed the Banyupahit River, whose waters are in fact rich in metals with negative consequences on the ecosystem of the valley.
