Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

In the afternoon of October 1, 2021, Hawaiian Volcano Observatory scientists observed the ongoing eruption within Halemaʻumaʻu from the northwest rim of the crater at Kīlauea's summit. The two dominant eruptive vents at this time are the western fissure (lower-right) and a fountaining area in the central-southern part of the lava lake (center), though minor spattering continues at other scattered vents.
