Kīlauea summit morning monitoring overflight on January 6, 2023 at 6:45 a.m. HST captures this aerial view of the new eruption within Halema‘uma‘u crater. The eruption is confined to Halemaʻumaʻu crater in the summit caldera. Lava flows have inundated much of the crater floor (which is nearly 300 acres or 120 hectares).

This image, taken early on January 6th, shows a lava fountain on the eastern portion of Halema‘uma‘u. Numerous areas of upwelling, like the one pictured here, are actively feeding the lava lake and re-surfacing material that was emplaced from activity in 2022. This fountain measured 16-33 feet in height (5-10 meters).

During the early morning hours of January 5, USGS Hawaiian Volcano Observatory scientists were closely monitoring an increase in earthquake activity and changes in the patterns of ground deformation at Kīlauea’s summit, indicating movement of magma in the subsurface.

This video, captured by the KWcam, shows a large burst of lava from the newly opened vent in Halema‘uma‘u crater, Kīlauea volcano at approximately 4:49 pm HST on January 5, 2023. This burst reached up to 50 meters (164 feet) high and sent a wave of lava across the crater floor.

On January 5, 2023, HVO’s KW webcam captured dramatic bursts of lava from a new vent that opened in Halemaʻumaʻu crater and a wave of lava that moved out onto the crater floor. USGS webcam image.

A new eruption began within Halema‘uma‘u crater, at the summit of Kīlauea just after 4:30 p.m. HST on January 5, 2023. Around 5:45 p.m. on the same day, an additional vent began erupting lava on the floor of the crater. The newer vent is located farther away in this image. USGS image by D. Downs.

The KWcam webcam, on the west rim of Kīlauea caldera, was upgraded on January 4, 2023, to a more advanced model, which provides a slightly wider view and higher image quality. This should provide an improved view of any future activity in Halema‘uma‘u. In this photo, an HVO scientist begins the process of the webcam swap. USGS photo by M. Patrick.

Geologists conducted a monitoring overflight of Kīlauea summit on the morning of December 10, 2022. They noted that the lava lake within Halemaʻumaʻu crater was mostly solidified, though incandescence was visible. USGS image by J. Bard.

Rare spotting! Dueling volcanoes captured by Landsat 9 satellite. Mauna Loa's 11.3-mile-long lava flow illuminates the plume of ash in the atmosphere above. The small red spot in the lower right is Kilauea—it began erupting nine days ago. USGS Volcanoes says a dual eruption has not occurred in Hawaii since 1984, making this a rare event.

This reference map depicts the ongoing Kīlauea summit eruption on November 25, 2022. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube.

This photo was taken the morning of November 23, 2022, at a moment when red molten material was visible in the inlet north of the west vent, which feeds into the lava lake. Incandescent material is intermittently visible in the inlet. USGS photo by K. Mulliken.

Uncrewed aircraft systems (UAS) flights on November 23, 2022, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The active lake surface is limited to the western portion of the crater.

View looking west of Halema‘uma‘u at the summit of Kīlauea volcano the morning of November 17, 2022. This photo is taken from the overlook near Keanakāko‘i Crater, which is publicly accessible. Lava is visible in the center of the photo, to the left of the top of the shrub in the foreground.

This tall, thin hornito on the eastern side of the crater floor of Halemaʻumaʻu is made up of spatter. The spatter made its way through a crack in the thick, solidified lava that forms the base of Halema‘uma‘u crater, at the summit of Kīlauea. The yellow and white patches at the bottom are from sulfur that has come out of the magma precipitating on the lava.

A mid-morning view of the southern portion of Halema‘uma‘u, as seen by field crews from the western rim. Activity within Halema‘uma‘u has remained steady over the last week. The active lake surface sits 7 meters (~23 feet) below the surface of the caldera. A small amount of spatter along the eastern margin of the lake was visible (the red glow).
