Icy blue fire and sulfur deposits

On the Indonesian island of Java, the Kawah Ijen Volcano boasts two of the world's most extraordinary occurrences. The first is a live solfatara, which produces hot, combustible sulfur fumes. These burn with an electric blue flame as they enter Earth's oxygen-rich atmosphere. Some of the gas condenses in the atmosphere, resulting in molten sulfur flows that burn with an electric blue flame as well. During the day, the flames are difficult to notice, but at night, they brighten the landscape. A one-kilometer-wide crater lake filled with turquoise-blue water is the second occurrence. The water's color is caused by its high concentration of dissolved metals and excessive acidity. With a pH as low as 0.5, it is the world's largest severely acidic lake. An inflow of hydrothermal waters charged with gases from a heated magma chamber below is the source of its acidity. So don’t fall yourself in the lake. Just enjoy the scenery it’s majestic! #ontheroad#tripinspired#hiking#nationalpark#naturalwonders#summervacation#hikingtrails#urbanexplorer
