The Hawaiʻi Department of Health has issued guidelines for residents and visitors as Kīlauea's activity continues. The U.S. Geological Survey reports that the summit eruption stopped last Wednesday morning, but another eruption could occur within days. While lava flow has paused, volcanic gas emissions continue, affecting air quality downwind of the summit, according to the Department of Health.
Southerly winds have brought volcanic gas to Hawaiʻi and Maui, causing vog conditions and fluctuating sulfur dioxide (SO₂) levels. The Department of Health advises residents and visitors to limit outdoor activities, especially those with respiratory conditions or children. Individuals with asthma or chronic illnesses should keep medication available and follow prescribed treatments. The Department of Health states, "People experiencing health effects should contact their medical provider as soon as possible if any symptoms develop, as respiratory conditions might worsen rapidly in heavy sulfur dioxide or vog conditions."
The Department of Health advises staying indoors, closing windows, and using air conditioners on recirculate to reduce exposure to vog and hazardous particles. Standard face masks do not block sulfur dioxide but can help limit inhalation of ash and Pele’s hair. Other recommendations include avoiding smoking, staying hydrated, and having a family emergency plan. Current air quality information and updates on Kīlauea are available on the Hawaiʻi Air Quality Data website and the Hawai‘i Interagency Vog Information Dashboard.
