The volcano that spews BLUE lava: Crater shoots out molten sulphur that looks red during the day but changes colour at night. Kawah Ijen volcano in East Java Indonesia produces molten suphur which leaks from its sides. Miners funnel it in to a crater where they allow it to cool before breaking it off in order to sell. The burning chemical appears red during the day but at night the blue flames become visible.

Mt Etna on Sicily locally called "Mongibello" is Europe's largest and most active volcano. Its frequent eruptions are often accompanied by large lava flows but rarely pose danger to inhabited areas. Etna is one of the volcanoes with the longest historic records of eruptions going back more than 2000 years.

At first glance you might think the otherworldly light in these pictures comes from a nebula or another planet deep in outer space.In fact it is made by burning sulphur which pours from the side of the Kawah Ijen volcano on planet Earth which is part of the Ijen volcano complex in East Java Indonesia. The molten chemical comes from the sides of the Kawah Ijen volcano in Indonesia and is directed through pipes by miners to collection points in a nearby crater While the sulhpur appears bright…
