Sulfur dioxide reacts in the atmosphere to create the visible haze known as vog (volcanic smog), which may cause respiratory and other problems, the agency said.

However, volcanic hazards are always present. Respiratory irritants from the eruption, including volcanic gases and vog (volcanic smog), are affecting communities far downwind.

One of the world's most active volcanoes, Kilauea, began erupting Monday at approximately 2 a.m. HST on Hawaii's Big Island, prompting health warnings as volcanic smog threatened downwind communities.

Jets of searing hot molten lava spewed more than 1,000 feet into the Hawaiian air Friday from the Kilauea volcano.

Hazards from this eruptive episode include elevated sulfur dioxide gas emissions, which can contribute to vog — a volcanic smog that affects air quality, particularly downwind of the summit.
