June 16, 2023 — View of Halemaʻumaʻu crater floor and eruptive vent

View—looking southwest—of the Kīlauea summit eruption within Halemaʻumaʻu, as captured during a Hawaiian Volcano Observatory helicopter overflight the morning of June 16, 2023. Lava can be seen erupting from a vent on the southwest crater wall in the background. Sulfur deposits on the partially submerged main island (formed during the early stages of the December 20, 2020 eruption) are visible in the center of the image. Active lava is confined to the southwest portion of Halemaʻumaʻu, on the far side of the island. Black, solidified lava in the foreground of the image was emplaced during the first few days of this eruption, which started on June 7, 2023. USGS photo by N. Deligne.
