Aerial view showing Keanakāko‘i crater, located on the south side of Kīlauea summit caldera. Crater Rim Drive, which remains closed to vehicles, is visible cross-cutting the image. Hawai‘i Volcanoes National Park has opened an eruption viewing area to the north of Keanakāko‘i crater, which is is visible in approximately the bottom center portion of the image.

Hawaiian Volcano Observatory geologists captured this view of Wahinekapu (Steaming Bluff) and the Steam Vents area within Hawai‘i Volcanoes National Park during a routine morning overflight on March 2, 2022. Cracks in this area allow heated groundwater, which reaches up to 63 degrees Celsius (145 degrees Fahrenheit), to escape from underground as steam.

On Friday, February 18, Hawaiian Volcano Observatory scientists visited the Halema‘uma‘u crater rim to observe the ongoing Kīlauea summit eruption. At the time of their visit, the lava lake in the western portion of the crater had drained substantially in association with deflation of the summit region.

Lava cascades from a pond north of the west vent in Halema‘uma‘u into the active lava lake in the western portion of the crater. On the afternoon of February 4, the pond was measured as about one meter (a few feet) higher than the larger lava lake at the summit of Kīlauea. USGS photo by K. Mulliken.

During the afternoon of February 4, HVO geologists observed abundant spattering within the perched margin of the active part of the lava lake in the west portion of Halema‘uma‘u at the summit of Kīlauea volcano. Over the weekend, the eruption has continued, with slight fluctuations in lava output. USGS image by K. Mulliken.

The west vent in Halema‘uma‘u was glowing as Kīlauea's summit eruption continued through the afternoon of February 4, 2022. From the west rim of Kīlauea caldera, HVO geologists could hear gas-jetting noises from the west vent, as well as from the spatter features on the inactive lava lake surface in the eastern portion of Halema‘uma‘u.

The small 20-meter (66 foot)-wide pond to the north of the west vent in Halema‘uma‘u crater. This pond feeds the active part of the lava lake at the summit of Kīlauea volcano via a small cascade of only a meter or two (several feet) down into the larger lava lake. This photo was taken around 9:30 a.m. on Tuesday, February 1, 2022, from the west rim of Halema‘uma‘u.

This unoccupied aircraft system (UAS) photograph shows the western eruptive vent (upper left) and lava pond (center right) within Halemaʻumaʻu crater during an eruptive pause on January 28, 2022. The pond hosts the only active lava in this view. The western impounding walls of the drained lava lake are visible from center to lower left of this image.

This reference map depicts the ongoing Kīlauea summit eruption on January 28, 2022. One eruptive vent is intermittently active within Halema‘uma‘u, along the western edge of the lava lake. When this vent is effusing lava, it pours into the active portion of the lake, colored red on this map.
