Volcanic haze, or VOG, is currently affecting air quality in Hawaii due to ongoing volcanic activity, primarily from the Kilauea volcano. VOG forms when sulfur dioxide and other volcanic emissions react with oxygen and moisture in the atmosphere, creating fine particulate matter. This haze can reduce visibility and pose significant health risks, particularly for individuals with respiratory conditions like asthma and bronchitis. Common symptoms of VOG exposure include respiratory irritation, coughing, sore throat, and headaches. Those with pre-existing respiratory issues, children, the elderly, and pregnant women are at higher risk.
