HVO geologists observed the new eruption within Kīlauea summit caldera during an eruption-monitoring overflight the morning of September 11, 2023. Multiple minor fountains remain active in the eastern portion of Halema‘uma‘u crater floor and on the downdropped block within Kīlauea's summit caldera.

A helicopter overflight on September 11, 2023, allowed for aerial visual and thermal imagery to be collected at the summit of Kīlauea. The eruptive activity continues with fountains active on the downdropped block, just east of Halema‘uma‘u crater, with lava pouring west onto the crater floor.

USGS Hawaiian Volcano Observatory geologists collected samples that erupted on September 10th, 2023, during the ongoing eruption within Kīlauea summit caldera. The samples were collected from within strategically placed buckets along the rim of the crater. The samples will be analyzed later for information about the lava erupted during the eruption.

During the morning of September 11, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within 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.

On September 11, 2023, HVO geologists deployed a new webcam to monitor the ongoing eruption at the summit of  Kīlauea. The S2cam is a temporary webcam showing Kīlauea caldera downdropped block and Halemaʻumaʻu crater; the view is from the north rim of the downdropped block and looking west. USGS image by M.

USGS Hawaiian Volcano Observatory geologists collected tephra samples erupted from Kīlauea summit on September 10th, 2023. The samples were collected from the rim of Halema‘uma‘u crater and range in size up to 1 inch (2.54 cm). This tephra was visibly less rounded than the existing tephra along the rim from the June 2023 eruption.
