A helicopter overflight on June 12, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The eruptive activity has consisted of lava fountaining and lava lake activity, confined within the crater. The area of active lava has diminished in recent days.

USGS Hawaiian Volcano Observatory gas specialists uses a FTIR (Fourier-transform infrared spectroscopy) spectrometer at the new eruption in Halema‘uma‘u crater that began on June 7, 2023. The FTIR measures the composition of the gases being emitted during the eruption by measuring how the plume absorbs infrared energy.

Hawaiian Volcano Observatory scientists use an FTIR to measure volcanic gas at the Halemaʻumaʻu crater eruption site. The FTIR is aimed at the hot, glowing lava and the volcanic gas between the lava and the FTIR can be measured.

On the afternoon of June 9, 2023, the fissure on the southwest wall of Halema‘uma‘u crater was still active and had formed a spatter cone. The vent was feeding lava flows down into the still active Halema‘uma‘u lava lake below. USGS photo by K. Lynn.

Low fountaining has been active where lava upwells into Halema‘uma‘u crater, at the summit of Kīlauea. This video shows a series of small fountains in the southern portion of the crater floor. Camera shake is due to high winds at the time.

The Hawaiian Volcano Observatory's B1cam was located on the east rim of the downdropped block within Kīlauea’s summit caldera, overlooking Halema‘uma‘u crater to the west. The eruption that began within Halema‘uma‘u crater the early morning of June 7, 2023, flooded the crater floor with lava and the B1cam was exposed to intense heat.

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.

View from the west rim of Halema‘uma‘u crater, showing the new lava flows that have covered the crater floor since the morning of June 7, 2023. This photograph, taken the morning of June 8, 2023, shows several active fissure vents that are feeding lava flows that cover the floor of the crater.

The eruption in Halema‘uma‘u crater, at the summit of Kīlauea, continues, as shown in this aerial image taken on June 8, 2023. Several lava fountains were active, with lava covering much of the western portion of the crater. The area of active lava on the surface has diminished over the past day, with lower lava fountains compared to yesterday. USGS image by M.

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.

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.

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.

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.

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.
