Blue lava, also known as (Indonesian: Api Biru), [1] and simply referred to as blue fire or sulfur fire, is a phenomenon that occurs when sulfur burns. It is an electric-blue flame that has the illusory appearance of lava .
The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C (1,112 °F). The flames can be up to five meters (16 feet) high; some of the gas condenses to liquid and is still ignited. [9] [10] Ijen is the largest blue flame area in the world. Local people refer to it as Api Biru (Blue Fire). [11]
The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
The water discharged near the power plant was heavily loaded with minerals, most notably in silica, and formed a silty body of water in the lava field, leading eventually to the construction of the Blue Lagoon in 1992. [33] During the seismic activity of November 2023, work was begun on a diversionary berm to protect the plant in case of an ...

A blue lava lamp. A classic lava lamp contains a standard incandescent or halogen lamp which heats a tall (often tapered) glass bottle. A formula from a 1968 US patent consisted of water and a transparent, translucent, or opaque mix of mineral oil, paraffin wax, and carbon tetrachloride.
Blue Mountains Basalts are igneous rocks occurring in the Sydney Basin in eastern Australia. This formation is up to 140 metres thick. Formed in the middle Miocene, some 17 million to 14 million years ago. [1] The remnants of this volcanic lava flow are confined to the higher altitudes in the western Blue Mountains.
