View of the active west vent from the south rim of the Halemaʻumaʻu crater on January 29, 2021. The west vent is almost completely crusted over and the effusion is slow from the base of the spatter cone. This photograph was taken from an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons.

HVO scientists observed the Halema‘uma‘u lava lake from the southern crater rim in the late afternoon on Tuesday. In this view, the active western fissure at Kīlauea's summit is visible to the left. The circulating western portion (left) of the lava lake has a more silvery color than the stagnant eastern portion (right).

Example of some of the new layers available in the Geology of Yellowstone Map as of early 2021. Shown here are the locations of various monitoring instruments and water sample sites overlain on a thermal infrared satellite image. Lighter colors on the infrared image show more radiant (warmer) areas, whereas dark areas are less radiant (cooler).

Cycles in Kīlauea's summit eruptive vigor were present on January 22 and 23, with the lava channel at Halema‘uma‘u's western fissure alternating between high and low flow rates over periods of 5-6 minutes. USGS photos by M. Patrick.

Active lava was again limited to the western half of the lava lake in Halema‘uma‘u at Kīlauea Volcano's summit. The western vent remained active with cycles of eruptive vigor in the open channel lasting 5-6 minutes. USGS photo by M. Patrick.

Active lava reached as far as the central lake in Halema‘uma‘u at Kīlauea's summit, on the east side of the main island, where crustal foundering was occasionally happening. USGS photo by M. Patrick.

Activity at the west vent within Halemaʻumaʻu crater on January 22 included frequent spattering from multiple locations and an open lava channel which drops 20 meters (65 feet) from its source to the lava lake surface.

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.
