Kīlauea Volcano Shows Continued Activity with Precursory Overflows
Kīlauea Volcano Shows Continued Activity with Precursory Overflows
US · Published Sep 24, 2026
• The US Geological Survey (USGS) has reported ongoing precursory overflows from the north vent of Kīlauea Volcano's Halemaʻumaʻu crater. The activity resumed on the night of September 22, 2026, with multiple overflows observed through the early hours of September
• These overflows produced lava flows extending a few hundred meters from the vent. The north, south, and west vents continue to emit glow and flames, with intermittent spatter bursts. The Hawaiian Volcano Observatory (HVO) has maintained the Volcano Alert Level at WATCH and the Aviation Color Code at ORANGE, indicating heightened unrest with an increased potential for eruption.

Impact & Risks

The eruption remains confined to the Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park, which is closed to the public. Volcanic gas emissions, including sulfur dioxide, pose respiratory risks, particularly in areas downwind of the vents. Tephra, such as volcanic ash and Pele’s hair, may fall near the vents and be carried further by wind, posing risks to skin, eyes, and respiratory health. Ground instability, including cracking and rockfalls, remains a significant hazard near the crater.
