During the morning of September 11, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within the Kīlauea summit caldera. The eruption is occurring in the east portion of Halemaʻumaʻu crater and on the downdropped block to the east, which formed during the 2018 summit collapse.

During an HVO eruption monitoring overflight on September 11, 2023, HVO geologist were able to land on the downdropped block within Kīlauea's summit caldera. They observed the line of erupting vents, several of which are visible in this video, as they searched for a safe location to collect a lava sample.

The B1cam, located on the east margin of the down-dropped block within Kīlauea caldera, captured the start of another eruption at the summit of Kīlauea volcano that began at 3:13 p.m. on September 10, 2023. This video shows a lava fountain bursting from a degassing area in the eastern portion of Halemaʻumaʻu crater, with the downdropped block in the foreground.

From the Uēkahuna overlook, the new eruption at the summit of Kīlauea is visible. The farthest east fissure is near the to margin of downdropped block that formed during the 2018 summit collapse. The base of the main fissure, which is farthest west (right on the image), is approximately 70 meters wide.
