The lake of active lava in the summit caldera of Kīlauea glows as the sun rises. Lava has covered more than 400 acres since the eruption began at 2:20 a.m. HST this morning. USGS image by N. Deligne. 

USGS Hawaiian Volcano Observatory geologists conducted a monitoring overflight of the new eruption in Kīlauea summit caldera. During the overflight, which occurred at 9:30 a.m. HST, they observed lava the active lava fountains and active lava flows at the base of the caldera, which have paved more than 500 acres with new rock.

Kīlauea's newest eruption samples contain olivine - a common green mineral in Hawaiian lavas. USGS Hawaiian Volcano Observatory and University of Hawai‘i at Hilo staff are picking out the olivine crystals like this one, shown using a microscope to magnify it (the crystal is 1 mm in size, or about 0.04 inches across), to analyze their chemistry.

Kīlauea volcano began erupting within the summit caldera at approximately 2:20 a.m. HST this morning, December 23, 2024, following an increase in seismicity that began beneath the summit just a half hour earlier, at approximately 2:00 a.m. HST.

From the closed area of Hawaiʻi Volcanoes National Park, USGS Hawaiian Volcano Observatory geologists documented the new eruption within Kalupele that started this morning at 2:20 a.m. HST.

Around 2:20 a.m. HST on December 23, 2024, Kīlauea's newest summit eruption began in Halema‘uma‘u. Lava fountains overnight reached up to 90 meters (295 feet) high and threw molten lava up and onto portions of the old Crater Rim Drive in a closed area of Hawai‘i Volcanoes National Park.

During an overflight at approximately 9:30 a.m. HST, USGS Hawaiian Volcano Observatory geologists captured this view of the eruption that began this morning at 2:20 a.m. HST in Kaluapele (Kīlauea summit caldera).

During an overflight at 2:30 p.m. HST today, December 23, USGS Hawaiian Volcano Observatory scientists were able to collect a molten sample of lava from the new eruption within Kaluapele. Kaluapele, the summit caldera of Kīlauea volcano, is the sacred home of the elemental force associated with volcanoes—Pele.

A HVO geologist inspected the KWcam enclosure for potential water entry points and found a weak seal. HVO staff will likely return in the future to make repairs to the enclosure or replace it all together. USGS photo by J. Barnett.

The KWcam on the eastern rim of Kaluapele (Kīlauea caldera) has been sending blurry images due water condensation inside the camera enclosure. On December 3rd, 2024, HVO staff visited the webcam to dry out the enclosure and search for any perforations that may be the source of the leak. USGS photo by H. Winslow.

HVO staff also visited the B1cam on the western side of Kaluapele (Kīlauea caldera) to remove water, replace desiccant packets, and clean off spider webs on the glass which were beginning to obscure the camera's view. USGS photo by H. Winslow.

On November 25, USGS Hawaiian Volcano Observatory geologists visited the site of the September 2024 eruption on Kīlauea’s East Rift Zone. Here, a shelly pāhoehoe lava flow (left) covered the base of a spatter cone (right) that grew around one of the lava fountains from an eruptive fissure vent. USGS photo taken by L. DeSmither.

Gas-rich lava flows near the September 2024 fissure vents created void spaces beneath the flow surface, which partially collapsed to reveal the base of these tree molds. USGS photo by L. DeSmither, taken on November 25, 2024.

With permission from Hawai‘i Volcanoes National Park, team of USGS Hawaiian Volcano Observatory geologists visited the site of the September 2024 Kīlauea middle East Rift Zone eruption. On November 25–26, they surveyed, sampled, and documented the new volcanic fissures and features, which formed west of and in Nāpau crater from September 15–20, 2024.
