Ijen Crater, East Java contain a Stunning Electric-Blue Flames that erupted from volcano and only accored every night wherein a dazzling electric-blue fire can often be seen streaming down the mountain at night, the blue fire glow unusual for a volcano with lava. The glow of blue flame is actually the light from the combustion of sulfuric gases, Grunewald explained, taht the gases emerge from cracks in the volcano at high pressure with temperature up to 1,112°F (600°C). When they come in contact with the air, they ignited, sending flames up to 16 feet (5 meters) high. Some of the gases condense into liquid sulfur, "which continues to burn as it flows down the slopes.
Blue volcanic fire was described in antiquity in Italy on the south slope of Mount Vesuvius and on the island of Vulcano. Blue flames crater may also be observed at the base of the plume of erupting volcanoes, when ash explosions occured. Kawah Ijen volcano is the subject of a new documentary released earlier this month that was produced by Grunewald and Régis Etienne, the president of Geneva's Society of Volcanology. Kawah Ijen Crater Lake, at the top of the volcano, is the world's largest such body of water filled with hydrochloric acid. In fact, it's the acid that makes the water green.
Cynthia Werner and Grunewald are a research geologist with the U.S. Geological Survey (USGS) at the Alaska Volcano Observatory, Werner explained how the lake became so acidic: The volcano emitted hydrogen chloride gas, which reacted with the water and formed a highly condensed hydrochloric acid with a pH of almost 0. The lake has a volume of 1.3 billion cubic feet (36 million cubic meters), or about 1/320 of the volume of Oregon's Crater Lake. As the burning gases cool, they deposit sulfur around the lake.
