Kīlauea summit eruption in Halemaʻumaʻu crater - September 29, 2021

At approximately 3:20 p.m. HST on September 29, 2021, an eruption began within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park. Fissures opened to the east of the large island within the lava lake that was active in Halemaʻumaʻu crater from December 2020 until May 2021, and are generating lava flows on the surface of the older lava lake. At approximately 4:43 p.m. HST, another vent opened on the west wall of Halemaʻumaʻu crater, and is visible in the left side of this image. USGS image.
