The word is a portmanteau of the words "volcanic" and "smog". [1] The term is in common use in the Hawaiian Islands, where the Kīlauea volcano, on the Island of Hawaiʻi (the "Big Island"), erupted continuously between 1983 and 2018. [2] Based on June 2008 measurements, Kīlauea emits 2,000–4,000 tons of sulfur dioxide (SO 2) every day. [3]
The latest eruption of a Hawaii volcano isn't threatening any infrastructure but health officials are warning the public about air-quality hazards from volcanic smog known as vog. Kilauea, one of ...
Volcanic gas monitoring is a standard tool of any volcano observatory. Unfortunately, the most precise compositional data still require dangerous field sampling campaigns. However, remote sensing techniques have advanced tremendously through the 1990s.
Volcanic smog, consisting of sulfate ions, was also detected far from Iceland with satellite imagery. The fissure was initially estimated to be over 1 km (0.62 mi) in length, but roughly an hour and a half later, the fissure had expanded to a width of 3.4 km (2.1 mi), consistent with the pattern observed in previous eruptions.

Although the eruption is occurring within a closed area of the park, high levels of volcanic gas-water vapor, carbon dioxide and sulfur dioxide-the visible haze known as vogâ ¯(volcanic smog ...
The lava that began spewing from Hawaii's Kilauea volcano earlier this month is no longer a threat to the public, but officials are now warning that the volcanic smog it’s emitting could include ...
