A view of HVO's old office building and the Jaggar Museum captured on an early morning overflight of Kīlauea summit. An inversion layer is sitting in the saddle between Kīlauea and Mauna Loa. An inversion layer forms when there is a temperature inversion of the atmosphere (warm air on top of cold air).

A helicopter overflight on January 10, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The active vents are located in the eastern portion of the crater, though lava has also filled the areas previously active in the western portion of the crater.

Photo of active lava lake in Halema‘uma‘u, at the summit of Kīlauea, taken during an helicopter overflight on January 8, 2023. Photo is taken from the east, and Mauna Loa appears in the background. Activity is focused in the eastern portion of Halema‘uma‘u, along with the basin within the western portion of the crater that was the focus of activity in 2021-2022.

The eruption within Halema‘uma‘u that began on January 5, 2023, continues, with activity concentrated primarily in the eastern part of the crater.

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). 

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.

This photograph from 9:45 PM January 5, 2023 shows the entire Halemaʻumaʻu crater floor in Kīlauea’s summit caldera resurfaced with new lava that welled out from below the central island.
