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 17, 2022 — Kīlauea summit overflight

A routine helicopter overflight on March 17, 2022, provided airborne views of the summit eruption in Halema‘uma‘u crater, at the summit of Kīlauea. At the start of the video, the helicopter flies over the edge of the large collapse depression formed during the 2018 eruption. The black lava filling the deepest portion of the crater has been erupted during the current eruption which began in September 2021.

A photograph taken during a helicopter overflight on the morning of March 17, 2022, shows an overview of Kīlauea Iki and Pu‘u Pua‘i. Pu‘u Pua‘i is a large cinder cone that formed as a result of the towering 1,900 foot (580 meters) lava fountains during the eruption of Kīlauea Iki. The Kīlauea Iki eruption began on November 19, 1959, and lasted for 5 weeks, with fountains of lava erupting from the vent in 17 separate episodes. USGS image by L. Gallant.
