View of the continuing eruption within Halema‘uma‘u at the summit of Kīlauea at dawn looking eastwards on January 11, 2023. Lava is erupting within the southeast portion of the crater (middle) and within the basin in the western half of the crater that was the focus of activity in 2021–2022 (center bottom).

A plume emanates from the western side of Halema‘uma‘u crater, at the summit of Kīlauea, reaching the clouds of the inversion layer. The eruption within Halema‘uma‘u continues, with activity concentrated primarily in the eastern part of the crater (not shown) and a basin in the western part of the crater that was the focus of activity during the 2021-2022 eruption.

HVO geologists on an early morning helicopter overflight captured this scene of Kīlauea and Mauna Loa. The weather patterns at the time of the flight were causing the plume to stagnate and sit in Halema‘uma‘u, creating this haze shown in the caldera. Lava is still actively erupting within Halema‘uma‘u, seen here as the orange glow. USGS image by L. Gallant.

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.
