Station KOHD on Kohala before being rebuilt in September 2023. The station was severely damaged by storms and heavy winds earlier this year. The site houses a seismic monitoring instrument and is also a repeater hub, meaning that it receives and relays data from other stations.

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.

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.

Hawaiian Volcano Observatory geologist are in the field today, September 11, monitoring the new eruption within Kīlauea summit caldera that began yesterday afternoon. From the scarp of the downdropped block on its north side, the active fissures on the downdropped block and Halemaʻumaʻu crater are visible.

On September 11, 2023, HVO geologists deployed a new webcam to monitor the ongoing eruption at the summit of  Kīlauea.

A new eruption at the summit of Kīlauea volcano began at approximately 3:13 p.m. on Sunday, September 10, 2023. This map depicts activity within Halema‘uma‘u on the second day of the eruption, September 11.

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.

After preparing the lava samples, the pressed pellets are loaded into the energy dispersive x-ray fluorescence (ED-XRF) instrument for analysis (box on the left in the image). The computer screen shows the spectral spikes for certain elements measured in the sample during the analysis.
