Volcano erupts “blue” lava on Dallol Mountain, Ethiopia (2014) photog. Oliver Grunewald
This is called a Cerulean eruption, and the blue tint that surrounds the lava comes from flames produced when escaping sulphuric gases burn. The volcano contains large amounts of pure sulfur, which emits an icy violet color as it burns, filling the air with toxic fumes.

While the term "blue lava" might sound like something out of science fiction, it's actually a real phenomenon that occurs when sulfur burns.

“(...) experts argue that the lava is not blue, instead the volcano contains large deposits of pure sulphur which gives off the incredible “neon blue” colour as it burns. When sulphur is spewed out at such high temperatures and pressures, its lava glows blue.”
“According to a Paris-based photographer, Olivier Grunewald, it is when the sulphuric gases come out of the vents or cracks in the volcano and get in contact with the oxygen-rich atmospheric air that the light is produced. This is the reason behind the blue flame which flows down the slope as burning hot liquid sulphur, after the sulphur gases condense, giving the illusion of lava flowing after a volcanic eruption.”
