Another view of the new eruption within the summit caldera of Kīlauea, Kaluapele, that began this morning, December 23, 2024, at approximately 2:20 a.m. HST. Lava is erupting from vents on the west part of the caldera wall, feeding lava flows that cover the area of Halemaʻumaʻu crater (with an approximate diameter of 1 kilometer or 0.75 miles).

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.

As of 9:30 a.m. HST, the plume (which is periodic in intensity) is still active and ejecting spatter and bombs onto the west rim of the caldera in the closed area along Crater Rim Drive Road.

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.

Panels A and B show what an interferogram would look like for a simple expanding spherical magma chamber from an ascending and descending orbital perspective. The star shows the true center of the inflating magma source. The arrow and bar denote satellite flight direction and look direction respectively. Each fringe represents approximately 1.55 cm.
