Halema‘uma‘u west vent on January 21, 2021

Between overcast and rainy weather, HVO field crews took this photo at 3:34 p.m. HST on January 21, 2021, from the south side of Kīlauea's summit caldera. The photo shows Halema‘uma‘u's active west vent, which overflowed its tubed-over lower half at 2:51 p.m. HST that afternoon.  It then proceeded to create a pāhoehoe flow (the lighter gray in the photo with a orange,

Lava lake on the evening of January 19, 2021

This photo, taken at just after 6 p.m. HST on January 19, shows that the western fissure continues to send lava into Halemʻaumaʻu crater through an open channel into the lava lake. The western side of the lava lake has an incandescent surface, while the eastern portion is more crusted over. However, lava continues to flow beneath this eastern portion, supplying breakouts

Small collapses of Kīlauea's western fissure continue

The western fissure at Kīlauea's summit continues to send lava into Halemʻaumaʻu crater through an open channel into the lava lake. Around sunset on the evening of January 19, field crews observed a minor collapse event of the spatter rampart on its northern rim and the channel margins at 5:46 p.m. HST. Times are indicated on each photo; the first image shows a "before"

Recent change in Halema‘uma‘u vent configuration - 01/18/2021

On the evening of January 17, the vent on the north side of the western fissure in Halema‘uma‘u at Kīlauea's summit activated and seemed to become the dominant vent overnight. This vent is the one on the right in this photo. The vent on the left, which was the dominant vent over the past week, seemed less energetic today. USGS photo by M. Patrick.

A close up of the southwest portion of the lava lake within Halema‘uma‘u, just south of the west fissure. The lava lake at Kīlauea's summit is perched, and is contained by a steep levee 2-3 meters (yards) high. USGS photo by M. Patrick.

Kīlauea — Recent Change in Vent Configuration (Jan 18, 2021)

This video shows the two main vents active at the western fissure in Halema‘uma‘u at Kīlauea's summit, with both supplying lava to the lava lake. Low fountaining was present at each vent.

Kīlauea — Low Fountaining Continues at Western Fissure (Jan 15, 2021)

Low fountaining remains active in the western fissure, supplying lava to the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Spatter deposits have built up a spatter cone around the vent. Occasional collapses of the unstable cone rim drop large chunks into the vent, disrupting the fountaining and creating a more chaotic spray of lava around the cone.

Low fountaining continues at the western fissure in Kīlauea's summit

Sunlight interacts with volcanic gas from Kīlauea's summit lava lake and western fissure in this late afternoon view. The western fissure has built a spatter cone on the steep walls of Halema‘uma‘u, with lava spilling into the active lake, which forms the lower right portion of the photo. The remnants of Crater Rim Drive, which collapsed during the 2018 eruption, can be

Low fountaining continues at the western fissure in Kīlauea's summit

A closer view of the low fountaining at the western fissure in  Halema‘uma‘u at Kīlauea's summit. The rim of the cone is built from accumulated deposits of spatter, and large chunks of the cone rim were observed to collapse from time to time. USGS photo by M. Patrick

Low fountaining continues at the western fissure in Kīlauea's summit

Low fountaining continues at the western fissure, supplying lava to the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. The vent has formed a spatter cone around the fountaining, with lava spilling into an open channel that plunges into the lake. HVO scientists continue to monitor the eruption from within an area of Hawai‘i Volcanoes National Park that remains

Kīlauea summit eruption overflight (Jan 12, 2021)

A helicopter overflight on the morning of January 12, provided airborne views of the lava lake and active fissure within Halema‘uma‘u, at the summit of Kīlauea. Low fountaining was present at the western fissure, with active surface lava limited to the western portion of the lava lake. The eastern half of the lake was covered by cooler, solidified surface lava.
