A telephoto view looking down on the fissure vent in the talus pile in the southwest corner of Halema‘uma‘u crater, taken from the western crater rim. Over the past 24 hours, this fissure vent has built up a spatter cone and spatter ramparts around its lava flow that cascades down to the crater floor.

A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. This photo, taken from the publicly accessible Kīlauea Overlook at approximately 5:30 a.m. HST, shows that lava is flowing on the crater floor and there are several active vent sources.

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.

HVO scientists conducted an overflight of the new eruption within Halemaʻumaʻu crater at the summit of Kīlauea volcano, within began the morning of June 7, 2023. This aerial photo shows that multiple vent sources are active on the crater floor, much of which has been covered with new lava over the past several hours.

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.

USGS Hawaiian Volcano Observatory geologists collected samples erupted on June 7, 2023, during the new eruption within Halemaʻumaʻu crater. The samples were collected from the rim of the crater, and range in size up to several inches (6 cm) in size. The samples will be analyzed later for information about the lava erupted during.

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.

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.

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.

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.

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.
