Kīlauea summit eruption in Halemaʻumaʻu crater - October 1, 2021

Aerial photo taken during a morning overflight on October 1, 2021, and looking at the west end of the lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. The west vent that is feeding this part of the lava lake is visible; the base of this vent was well above the lava lake when it opened on the afternoon of September 29, 2021. Since then, the lava lake has risen to the base of this vent. USGS photo by D. Downs.
