The text states that there are volcanoes that release blue lava.
The claim that volcanoes release blue lava is misleading. The phenomenon observed at Kawah Ijen in Indonesia is not actual blue lava but rather blue flames caused by the combustion of sulfuric gases. This has been confirmed by multiple sources, including Snopes, which rated similar claims as 'Miscaptioned.' Therefore, the claim is technically incorrect but based on a real phenomenon that is often misunderstood.
