Volcanic smog (vog) is a visible haze comprised of gas and an aerosol of tiny particles and acidic droplets created when sulfur dioxide (SO2) and other gases emitted from a volcano chemically interact with sunlight and atmospheric oxygen, moisture, and dust.
Called Blámóða in Icelandic, or blue smog… blámóða killed thousands of Icelanders 1783-1785 when a volcano erupted.
The video was captured on July 2.
