A new Kīlauea summit eruption within Halema‘uma‘u crater began at approximately 3:20 p.m. HST on September 29, 2021, with fountains appearing on the central crater floor, creating a new lava lake. This video shows the dominant fountain, south of the lake center, on the evening of September 29, 2021. USGS video by M. Patrick.
A new eruption at the summit of Kīlauea on Hawaiʻi Island began on Wednesday afternoon, Sept 29, 2021.
The USGS Hawaiian Volcano Observatory reports that lava activity is currently confined within Halema’uma’u crater. Gas emissions and seismic activity at the summit remain elevated.
Areas of volcanic glass or Pele’s hair have been observed near the Halemaumau summit of Kilauea on Wednesday evening, as reported by several pilots in the vicinity.

Residents and visitors are urged to minimize exposure to volcanic emissions, particularly those with respiratory sensitivities.
Just after 4:40 p.m., (9.29.21) a new vent opened on the west wall of the crater, and the initial moments were captured in this video. USGS video by Matt Patrick, Hawaiian Volcano ObservatoryKīlauea volcano is erupting. With the summit eruption continuing through the night, HVO scientists monitor the eruption for changes in activity and volcanic hazards. High levels of volcanic gases are the primary hazard of concern, as this hazard can have far-reaching effects down-wind. USGS photo taken by D. Downs.The eruption within Halema’uma’u, at Kīlauea summit within Hawai’i Volcanoes National Park, continues at dawn on Sept. 30, 2021. Fountaining at multiple fissure locations on the base and west wall of the crater continues, and a lava lake is growing within Halema’uma’u. The Kīlauea summit webcams provide near real-time views of this activity: https://www.usgs.gov/volcanoes/kilauea/summit-webcams. USGS image by B. Carr. An eruption began within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park, on Sept. 29, 2021. Vigorous lava fountains formed in the middle part of the lava lake that was active in Halemaʻumaʻu crater from December 2020 until May 2021. The lava fountains fed lava flows that quickly covered the entire floor of Halemaʻumaʻu crater. USGS image. At approximately 3:20 p.m. HST on Sept. 29, 2021, the USGS Hawaiian Volcano Observatory (HVO) detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park. Webcam imagery shows fissures at the base of Halemaʻumaʻu crater, within the area circled on this image. These fissures are generating lava flows on the surface of the lava lake that was active until May 2021, which is visible on the basemap generated from aerial visual and thermal imagery collected on June 8, 2021. The scale of the base thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures.

Patrick.The eruption that began on Sept. 29, within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park, is generating a vigorous plume of volcanic gas. The volcanic gas, which includes sulfur dioxide (SO2), interacts in the atmosphere with oxygen, moisture, dust, and sunlight over minutes to days and forms volcanic air pollution, or VOG, which can be transported downwind.
