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.

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.

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.

A telephoto view of the west vent area within Halema‘uma‘u crater, at the summit of Kīlauea. 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.

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).

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.

View looking to the west on the crater floor of Halemaʻumaʻu, at the summit of Kīlauea. The foreground is covered by pāhoehoe, and the brown-colored feature in the background is the island that has persisted since the December 2020 eruption within Halema‘uma‘u. USGS photo by D. Downs.

A hornito located on the eastern side of Halemaʻumaʻu crater floor. The colorful nature of the hornito comes from the various gases that come out of the magma and precipitate on the surrounding rock. Many of these colors are from sulfur that is abundant in Kīlauea magmas. USGS photo by D. Downs.

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.

Orange lava can be seen spattering on the east side of the active lava lake. USGS photo taken at 9:35 a.m. HST on November 10, 2022, by J.M. Chang.
