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.

Hawaiian Volcano Observatory geologists scouted the perimeter of Halemaʻumaʻu crater floor for a location to sample lava erupted by new vents that opened the morning of June 7, 2023. Initial lava flows inundated the crater floor (an area of approximately 1.5 square km or 370 acres) and added about 10 meters (32 feet) depth of new lava.

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.

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.
