January 20, 2023 — Lava lake activity in Halema‘uma‘u, Kīlauea
Lava lake activity continues in Halema‘uma‘u crater, at the summit of Kīlauea, on January 20, 2023. Lava upwells at the fountain source and spreads out towards the lake margin, where it downwells. Overall, activity in the crater has been steady in recent days. USGS photo by M. Patrick.

January 19, 2023 — Perched lava lake within Halema‘uma‘u crater, Kīlauea
View of the active lava lake in the eastern side of Halema‘uma‘u crater, at the summit of Kīlauea. A perched levee consisting of stacked crustal plates a few meters (yards) tall surrounds the lake. A fountain (orange) is present on the southwest side of the lake. At the time the photo was taken, a flow had breached the levee on the south (right) side.

January 17, 2023 — Kīlauea summit thermal map compilation
This compilation shows thermal maps since the start of the eruption in Halema‘uma‘u, at the summit of Kīlauea. The map sequence shows the focusing of lava lake activity into two main lakes on the crater floor. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures.

January 17, 2023 — Kīlauea summit thermal map
A helicopter overflight on January 17, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The largest lava lake is located in the eastern portion of the crater, though lava has also filled the areas previously active in the western portion of the crater.

January 17, 2023 — Kīlauea summit eruption overflight
Lava lake activity continues in Halema‘uma‘u crater, at the summit of Kīlauea volcano. This photo from the January 17 overflight looks west and shows that the eastern lake, in the foreground, remains stable. This eastern lake is supplied by a single fountain marked by the bright spot of incandescence.

January 17, 2023 — Video from Kīlauea summit eruption overflight
The eruption in Halema‘uma‘u crater, at the summit of Kīlauea, continues with steady lava lake activity. The largest lake is in the eastern portion of the crater, and is supplied by a single fountain. A smaller lake is also active in the western portion of the crater, along with two other much smaller lakes. USGS photo by M. Patrick.

Seismic instruments deployed across the southeast part of the Island of Hawai‘i
The location of permanent and temporary seismic instruments deployed across the southeast part of the Island of Hawai‘i. Shaded white areas show dense regions of earthquakes interpreted as the Pāhala sill complex. Dashed white box outlines a region of sparsely spaced volcano-tectonic earthquakes that lie between the Kīlauea summit and Pāhala.
