Station KOHD on Kohala after being rebuilt in September 2023. The site 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.

View of the eruptive vents from the east side of Kīlauea caldera, looking west-northwest toward Kīlauea Overlook. Mid-day on September 14, 2023, the cone in the foreground of the image had mild spattering within ponded lava inside the cone. USGS photo by K. Lynn.

A row of scones in Halema‘uma‘u are actively ejecting spatter, which helps build the height of each structure. Cone heights of 20 meters (66 feet) have been measured by field teams. Of the line of vents spanning 0.8 miles (1.4 km) that were observed active during the initial phases of the eruption, only six remain active as of September 14, 2023. USGS photo by L.

This telephoto view shows one of the erupting vents in Kīlauea caldera. Lava fountain heights at the vents reached up to about 10-15 meters (32-50 feet) and the horseshoe-shaped spatter ramparts that have accumulated on the south/downwind side of the vents remain 20 meters (66 feet) high.

Station KOHD on Kohala houses a seismometer and a repeater, meaning that data is both collected and relayed at this station. The station was severely damaged by storms and heavy winds earlier this year. HVO field technicians rebuilt the station during the week of September 11.

This overview of the Kīlauea summit eruption was captured in the afternoon of Tuesday, September 12, from the southeast rim of Kaluapele. Multiple eruptive vents (bottom) on the downdropped block to the east of Halema‘uma‘u crater are effusing a river of lava into the deeper western side of the crater in the distance. USGS photo by M. Zoeller. 

During an eruption monitoring overflight mid-day on September 12, 2023, activity in Kīlauea caldera was focused on six active vents that were producing lava fountains and flows. In this photo, oriented looking toward the southwest, several inactive fissures on the northeast side of the downdropped block appear silver and brown in color.

These tephra and spatter clasts were eruption recently at the summit of Kīlauea. They were collected from an inactive fissure on September 12, 2023, and brought back to the lab where they will be analyzed in several ways, including their density, shape, size, and chemistry. The larger clast on the bottom is about 8 inches (20 cm) long. USGS photo by K. Lynn.

From Kīlauea caldera floor overlooking the downdropped block, HVO scientists had a beautiful view of the six erupting vents on the floor of the downdropped block.  HVO scientists were on the caldera floor retrieving seismic nodes, which had been deployed during the Kīlauea Seismic Imaging Project earlier this year.

Tephra created within approximately the first 18 hours of the eruption that began in Kīlauea caldera the afternoon of Sunday, September 10, were collected on September 12, 2023, and dried in the lab overnight. Today, these samples will be processed for various analyses to determine what the lava composition is and what minerals it might contain, such as olivine.

During the week of September 11, Hawaiian Volcano Observatory field engineers rebuilt station KOHD on Kohala, which had been severely damaged by storms and heavy winds earlier this year. In this photo, a new concrete pad is being built to hold the heavy battery box that help to power the site. USGS photo by M. Warren.

The former Hawaiian Volcano Observatory building, perched on Kīlauea caldera rim, has spectacular views of the summit eruption. The tower was built with a vision of overlooking eruptions such as this one. This building was damaged during the 2018 summit collapse and is slated for deconstruction later this year.

During the afternoon of September 12, 2023, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within Kīlauea summit caldera. The eruption is occurring on the downdropped block east of Halema‘uma‘u, which formed during the 2018 summit collapse.
