Photo of Halema‘uma‘u crater, at the summit of Kīlauea, taken from the southeast corner of the crater during an early morning helicopter overflight on Sunday, January 8, 2023. The eruption within Halema‘uma‘u that began on January 5, 2023, continues, with activity concentrated primarily in the eastern part of the crater.

Several areas of active upwelling on the surface of Halema‘uma‘u, as seen from the south rim during an early morning observational shift on January 6, 2023. As the lava reaches the lake's surface, it immediately begins to cool and radiates away from the source.

A new eruption at the summit of Kīlauea volcano began at approximately 4:34 p.m. on Thursday, January 5, 2023. This reference map depicts activity on the second day of the eruption, based on measurements taken from the crater rim at approximately 9:00 a.m. this morning.

View of eastern half of lava lake within Halema‘uma‘u, Kīlauea summit, in the early morning of January 6, 2023. In this view looking north, four active lava fountains are visible, three in the center of the photo and one in the middle right (smaller).

Kīlauea summit morning monitoring overflight on January 6, 2023 at 6:45 a.m. HST captures this aerial view of the new eruption within Halema‘uma‘u crater. The eruption is confined to Halemaʻumaʻu crater in the summit caldera. Lava flows have inundated much of the crater floor (which is nearly 300 acres or 120 hectares).

This image, taken early on January 6th, shows a lava fountain on the eastern portion of Halema‘uma‘u. Numerous areas of upwelling, like the one pictured here, are actively feeding the lava lake and re-surfacing material that was emplaced from activity in 2022. This fountain measured 16-33 feet in height (5-10 meters).

During the early morning hours of January 5, USGS Hawaiian Volcano Observatory scientists were closely monitoring an increase in earthquake activity and changes in the patterns of ground deformation at Kīlauea’s summit, indicating movement of magma in the subsurface.

On January 5, 2023, HVO’s KW webcam captured dramatic bursts of lava from a new vent that opened in Halemaʻumaʻu crater and a wave of lava that moved out onto the crater floor. USGS webcam image. 

This video, captured by the KWcam, shows a large burst of lava from the newly opened vent in Halema‘uma‘u crater, Kīlauea volcano at approximately 4:49 pm HST on January 5, 2023. This burst reached up to 50 meters (164 feet) high and sent a wave of lava across the crater floor.

The KWcam webcam, on the west rim of Kīlauea caldera, was upgraded on January 4, 2023, to a more advanced model, which provides a slightly wider view and higher image quality. This should provide an improved view of any future activity in Halema‘uma‘u. In this photo, an HVO scientist begins the process of the webcam swap. USGS photo by M. Patrick.

Geologists conducted a monitoring overflight of Kīlauea summit on the morning of December 10, 2022. They noted that the lava lake within Halemaʻumaʻu crater was mostly solidified, though incandescence was visible. USGS image by J. Bard.

Rare spotting! Dueling volcanoes captured by Landsat 9 satellite. Mauna Loa's 11.3-mile-long lava flow illuminates the plume of ash in the atmosphere above. The small red spot in the lower right is Kilauea—it began erupting nine days ago. USGS Volcanoes says a dual eruption has not occurred in Hawaii since 1984, making this a rare event.

This reference map depicts the ongoing Kīlauea summit eruption on November 25, 2022. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube.
