September 18, 2023 — Overview of recent Halema‘uma‘u eruption site
This overview of the recent eruption site within caldera at the summit of Kīlauea was captured during a Hawaiian Volcano Observatory helicopter overflight on Monday, September 18, 2023. Looking to the east-northeast from above the western crater floor, the now-inactive eruptive vents form a cluster of small black cinder cones in the upper-right quadrant of the photo. The eruption covered approximately 496 acres (201 hectares) with new lava; most of this area is visible here. USGS photo by M. Zoeller.
