The text claims that some volcanoes release blue lava.
Infact verdict: Mostly False (21/100).
The claim that volcanoes release blue lava is misleading. Professional fact-checking by Snopes classified images of blue lava as 'Miscaptioned', clarifying that these images are of blue flames caused by burning sulfur at volcanoes like Indonesia's Kawah Ijen and Ethiopia's Dallol, not actual blue lava. Additional web evidence from reliable sources such as Wikipedia and National Geographic corroborate that the blue appearance is due to sulfuric flames, not lava itself. Thus, the claim is false, and the natural phenomenon is due to sulfur combustion rather than blue lava.
