In Indonesia, there is a volcano that inexplicably spews blue lava. There are sulfuric gases that get released during an eruption, which then changes the color of the lava. The blue-colored flames meld into liquid sulfur. Technically, it's not lava and can be very toxic is anyone nearby who might have breathed it in.
