The eruption at Kīlauea summit lights up Christmas Eve, as viewed from the overlook at Volcano House within Hawaiʻi Volcanoes National Park. A plume of volcanic gas and fine volcanic particles rises above the erupting vents before it is transported downwind, generally in a southwest direction within a closed area of the National Park.

The eruption at Kīlauea volcano that began yesterday, December 23, slowed starting around 3 p.m. HST yesterday. The eruption paused through the night and reactivated this morning at several of the vents along the southwest of Halema‘uma‘u crater floor.

This photo was taken at 9:20 a.m. HST on Christmas Day, December 25, and shows vigorous lava fountains and a towering gas plume at the summit of Kīlauea. Just an hour later, eruptive activity at the vent began to greatly decrease. USGS photo by L. Gallant.

This aerial view, captured during a USGS Hawaiian Volcano Observatory monitoring overflight, shows the lava fountains active in the west part of Kīlauea caldera. The eruption began this morning at 2:20 a.m. HST, December 23, and fountains reached up to 90 meters (290 feet) overnight.

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.

This photograph, taken at approximately 4:00 a.m. HST from the Volcano House overlook in Hawaiʻi Volcanoes National Park, shows the new eruption within Kaluapele (the summit caldera).

This thermal map shows lava flows covering the floor of Halemaʻumaʻu crater at the summit of Kīlauea.  Fountaining was active in the southwest portion of the caldera, with flows extending east onto the downdropped block. Cooler colors (purple, black) show lower temperatures while hotter colors (orange, yellow) show higher temperatures. USGS map by M.

The new Kīlauea summit eruption is occurring within a closed area of Hawai'i Volcanoes National Park. High levels of volcanic gas—primarily water vapor (H₂O), carbon dioxide (CO₂), and sulfur dioxide (SO₂)—are the primary hazard of concern, as this hazard can have far-reaching effects down-wind.

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.
