An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Lava activity is currently confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

February 4, 2022 — Kīlauea summit eruption observations

The lava lake in Halema‘uma‘u crater at the summit of Kīlauea was visibly full beneath overcast skies during a Hawaiian Volcano Observatory eruption monitoring field shift on February 4, 2022. This photo was taken from west rim of the Kīlauea caldera, in the vicinity of the KWcam. USGS photo by K. Mulliken.

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.
