A telephoto view of a lava fountain in the east side of the lava lake within Halema‘uma‘u. This photo was taken during a helicopter overflight over 8 hours after the Kīlauea summit eruption within Halema‘uma‘u started on June 7, 2023. Fountain heights had already decreased from the early stages of the eruption.

A helicopter overflight on June 7, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The overflight happened about two hours after the start of the new eruption at the summit, and eruptive activity consisted of lava fountaining and lava lake activity.

A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.

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.

Duane Champion (shown here on the left, with two coworkers) helped us to unlock Pele’s secrets by studying the magnetic properties preserved in lava flows. A good friend and valuable colleague, he greatly improved our ability to reconstruct past geological events using paleomagnetism. He will be missed.
