New USGS fact sheet provides information on volcanic air pollution in Hawaii.

Release Date:

Volcanic Air Pollution Hazards in Hawaii is an updated fact sheet that provides information on the science of Kīlauea's volcanic air pollution, known as "vog."

It also addresses impacts to human health, agriculture, infrastructure, and the environment, and guides readers to relevant resources for living with vog.

Noxious sulfur dioxide gas and other air pollutants emitted from Kīlauea Volcano on the Island of Hawaiʻi react with oxygen, atmospheric moisture, and sunlight to produce volcanic smog (vog) and acid rain. U.S. Geological Survey scientists, along with health professionals and local government officials are working together to better understand vog and to enhance public awareness of this hazard.
