Where is there blue lava?
Where is there blue lava? The most famous of these fires occur regularly on Indonesia's Kawah Ijen volcano, on the island of Java, which has some of the highest levels of sulfur in the world and is also a site of sulfur mining. Due to the occurrence of the flames, Kawah Ijen has also been nicknamed the Blue Volcano.
Is blue lava hotter than the sun?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the photosphere), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
