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 monitor the ongoing Kīlauea summit eruption from within an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons. They are equipped with a range of specialized safety gear and personal protective equipment such as gas masks, helmets, gloves, and eye protection.

As of 9:30 a.m., multiple vents remain active in the ongoing eruption at Kīlauea summit. Most vents are on the crater floor; however, one fissure is in the southwest wall of Halemaʻumaʻu crater. This fissure is located about 30 meters (100 feet) above the lava lake surface and is approximately 20-25 meters (65-80 feet) long. 

Lava that is less than one day old drapes over lava from the late nineteenth to early twentieth centuries on Halemaʻumaʻu crater floor. By the time Hawaiian Volcano Observatory geologists arrived, this lava at the perimeter of Halemaʻumaʻu was solid but still warm to touch, having erupted earlier that day.

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.

Lava fountaining from a fissure that cut across the southwest wall of Halema‘uma‘u on June 7, 2023, had built up a small cone structure by mid-day. The fissure was intermittently obscured by plumes of volcanic gases throughout the day. USGS photo by K. Lynn.

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.
