At approximately 3:20 p.m. HST on September 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. USGS map by M. Patrick.
