^{The Blue Lava of Kawah Ijen Volcano. The ‘blue lavas’
are a rare phenomenon, only visible on the Kawah Ijen Volcano, in
Indonesia. It may look like the volcano is spewing blue lava, but in
fact, the shocking blue fire occurs when the volcanic sulphuric gases
combust. Emerging from cracks in the volcano’s side, these gases ignite
when coming into contact with air. It’s not actual blue lava, but blue
flames. (video)}
