The ongoing activity at Kīlauea poses risks to the surrounding areas, including the potential for lava flows, ground deformation, and volcanic gas emissions. High levels of sulfur dioxide and vog (volcanic air pollution) can cause respiratory issues and other health problems for residents and visitors. The possibility of intrusive activity or new eruptive vents adds to the uncertainty and potential hazards. The area around Halemaʻumaʻu crater remains closed to the public due to the risk of ground cracks, rockfalls, and other dangers.
