The Volcano That Spews Blue Lava
This volcano in Kawah Ijen has some spectacular blue lava by night, but shows red during the day. It is the sulphur inside the volcano that causes the change in color.

I was there one month ago, it really is that blue but it also generates a lot of toxic sulfur smoke so you have to go down the crater using a gasmask. More disturbedly, every day some miners are going down without any sort of protection to harvest the sulfur and climb their way back to the top of the crater and later down the hill carrying more than 80kg of sulfur. Crazy!
