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

July 13, 2022 — Summit eruption in Halema‘uma‘u

A telephoto image of the active lava lake within Halema‘uma‘u crater, at the summit of Kīlauea, taken on July 13. During the current deflationary tilt phase of a deflation-inflation event, the active lava lake level is about 9 m (30 ft) below the lake rim. The west vent cone (lower right) is about 24 m (79 ft) tall, with a few areas that were weakly incandescent. USGS photo taken by L. DeSmither from the west rim of Halema‘uma‘u.
Color photograph of scientist in field
A Hawaiian Volcano Observatory scientist uses a laser rangefinder to measure the distance to different areas of interest around the crater. These measurements help us to track changes in the lava lake and crater floor, and to measure features such as the lava lake and west vent cone. USGS photo taken by L. DeSmither on July 13, 2022.

A photo of Halema‘uma‘u crater, at Kīlauea summit, taken on July 13 from the western rim of the crater. SO2 gas emissions remain elevated and were measured at about 1250 tonnes per day on July 14. Volcanic gases, and steam from rain on the crater floor, often obscured visibility with only intermittent views of the crater floor and active lava lake. USGS photo taken by L. DeSmither.
