Kīlauea Eruption: Gas Plume and Vog Hazard #Volcano #Science

#Volcano #Eruption #Geology #Shorts
Filmed at Halemaʻumaʻu crater, Hawai‘i Volcanoes National Park, September 11, 2023, 2:00 p.m. HST. Volcanic gas emissions dominated the summit eruption, with sulfur dioxide output exceeding 100,000 tonnes per day. The gas formed vog—volcanic smog created when SO₂ reacts with sunlight, oxygen, and moisture—across Hawai‘i Island, reducing visibility and impacting air quality.
