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.

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.

In the early evening on June 7, 2023, the fissure in the southwest wall of Halema‘uma‘u had built up walls of spatter around the fountain. The fissure was continuing to pour lava down the talus slope into the active lava lake below. USGS photo by K. Lynn.

Data recorded on June 7, 2023, by five seismometers located in Kīlauea summit region. The data is shown as spectrograms, which display the energy of seismic events (vertical axis) occurring over time (horizontal axis).

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.
