An eruption began on June 7 in Halema‘uma‘u crater, at the summit of Kīlauea. Just a few hours after vents opened in the central part of the crater, a new vent formed on the crater wall, sending a cascade of lava into the growing lava lake.

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.

A view across the Halemaʻumaʻu crater floor, at one of the new vents that began erupting on June 7, 2023. Fountain heights have decreased since the eruption onset and, as of approximately 3 p.m., were about 4-9 meters (13-30 feet) high. The new eruption is confined to Kīlauea summit region, within Hawai‘i Volcanoes National Park.

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.

These fountains were approximately 4-9 meters (13-30 feet) high throughout the afternoon, with occasional bursts that were higher. USGS photo by K. Lynn.

Scientists observed wind vortexes during the first day of the new eruption in Halemaʻumaʻu crater, which began before sunrise on June 7, 2023. These vortexes form due to extreme head. The rapidly swirling air can entrain hot lava, flinging pieces of crust. Scientists maintained a safe distance on the rim of the crater and used a telephoto lens to take this photo.

A timelapse camera captures the new eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The initial intensity of the eruption covered the crater floor with lava, fed by numerous fountains. As the eruption stabilized and the vigor declined, the area of active lava on the surface was reduced.

A new eruption at the summit of Kīlauea volcano began at approximately 4:43 a.m. on Wednesday, June 7, 2023. This reference map depicts activity in the first two hours of the eruption, based on measurements taken from the crater rim at approximately 6:00 a.m.

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).

This photo, captured by the Hawaiian Volcano Observatory's KWcam on the northwest rim of the caldera, shows the opening phase of the eruption that began within Halemaʻumaʻu crater the early morning of June 7, 2023. A lava fountain bursts from a vent in the central part of the crater floor and lava begins to flood the surrounding area.

A new eruption began on June 7 in Halema‘uma‘u crater, at the summit of Kīlauea. This photograph shows moments from the opening hours of the eruption, with an increase in vigor at vents in the western portion of the crater floor.

Kīlauea volcano is erupting. At approximately 4:44 a.m. HST on June 7, 2023, the USGS Hawaiian Volcano Observatory detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park.
