An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Intermittent lava activity is 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.

March 11, 2022 — Kīlauea summit

Wide view of a volcanic crater with an active lava lake at the bottom
A view of Halema‘uma‘u at Kīlauea summit, looking east, on the morning of March 11. The active lava lake is silvery gray and is visible in the lower right. The remnants of the west vent cone area are visible to the west (bottom right) of the active lava lake, and are the source of the majority of bluish-white volcanic gas emissions. USGS image by N. Deligne.
Telephoto view of an active lava lake with a degassing eruptive vent
Telephoto view looking east of the active lava lake within Halema‘uma‘u crater at the summit of Kīlauea on March 11, 2022. The craggy remains of the west vent cone, which has broken down over the past few weeks, are visible through the volcanic gas plume in the lower right. Lava supplies the lake through a small embayment and spillway (bottom center) just north of the west vent cone area. From the main active lava lake, some lava spills over a narrow divide into a second smaller lake to the southeast (upper right). USGS image by N. Deligne.
Telephoto view of an active lava lake with thick volcanic gas emissions
Telephoto view, looking east, of the lava source area for the active lava lake within Halema‘uma‘u at the summit of Kīlauea on March 11. The is supplied from the embayment which is just north (left) of the remnants of west cone area (center and right). From there, lava flows through a narrow spillway and then pours into the active lava lake, which has a silvery grey appearance. Over the past few weeks, the west vent cone area has broken down and lava has infilled between its craggy remnants. The tallest remnant to the south (right) rises 27 meters (89 feet) above the crater floor. USGS image by N. Deligne.
