Amazing Pictures Of Blue Lava
Photographer Reuben Wu has captured incredible images of blue lava flowing from a volcano at Ijen on the Indonesian island of Java.
The vast majority of lava flows are red, due to the large amount of thermal radiation. In this case, however, the lava is actually burning something else: pockets of sulfur, which spew out of the volcanic crevices along with the molten rock.
