Kīlauea Volcano Shows Signs of Renewed Activity
US · Published Sep 22, 2026
The US Geological Survey (USGS) has issued an update on the ongoing activity at Kīlauea Volcano in Hawai'i. According to the USGS Hawaiian Volcano Observatory (HVO), the north, south, and west vents of the volcano continue to emit glow and minor intermittent spatter, with strong seismic tremors recorded across the summit. The volcano has been erupting episodically since December 23, 2024, with the most recent episode, Episode 54, occurring on August 25,
During this episode, lava fountains reached heights of up to 150 meters, and the eruption lasted for nine hours. The current activity includes slow summit inflation, with the system nearing its maximum inflation level of 16 microradians. The alert level remains at ORANGE/WATCH, indicating heightened unrest with an increased potential for eruption.

Impact & Risks

The ongoing activity at Kīlauea poses significant risks to the surrounding areas, particularly within the closed region of Hawai'i Volcanoes National Park. High levels of volcanic gases, including sulfur dioxide (SO2), continue to be emitted, creating hazardous conditions for those downwind. These emissions can lead to vog (volcanic air pollution), which may cause respiratory and other health issues. Additionally, tephra, or volcanic fragments, can cause skin, eye, and respiratory irritation. Lava flows and ground instability around the caldera remain a concern, with potential for rockfalls and landslides. Residents and visitors are advised to minimize exposure to these hazards.
