Blue Fire at Ijen Volcano Crater

Occurred on September 2023 / Kawah Ijen, Banyuwangi, Java, Indonesia

Info from Licensor: "Took this video on the Ijen Crater Trek at Banyuwangi, Java, Indonesia. Kawah Ijen is an active volcano. Here, extremely high quantities of sulfuric gases emerge at high pressures and temperatures (sometimes more than 600°C) along with the lava. When sulfur from within the volcano breaches the surface, it can reach temperatures up to 600°C (1,112°F), and therefore the sulfur immediately encounters lower temperatures and pressures at the surface, which causes the sulfur to immediately ignite and erupt blue flames up to five meters (16 ft) into the air."
