Kīlauea images of eruptive activity, field work, and more.
On January 12, 2026, Kīlauea had its 40th fountaining episode of the ongoing eruption within Halema‘uma‘u. This view was taken at 10:50 a.m. H.S.T. from the publicly accessible viewing area at Uēkahuna within Hawaiʻi Volcanoes National Park, showing north vent fountaining. USGS photo by N. Deligne.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. The data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on January 2, 2026; as such, the provided statistics are reflective of the first thirty-nine episodes of the eruption through December 24, 2025.

On January 12, 2026, Kīlauea had its 40th fountaining episode of the ongoing eruption within Halema‘uma‘u. This photo was taken at 4:37 p.m. HST from the publicly accessible viewing area at Kūpinaʻi Pali (Waldron's Ledge) within Hawaiʻi Volcanoes National Park, showing north vent fountaining. The episode ended about an hour and a half after this photo was taken.

USGS Hawaiian Volcano Observatory geologists observe episode 40 fountains from the Uēkahuna overlook within Hawai‘i Volcanoes National Park. This episode had multiple days of precursory overflows from both the north and south vents, leading to fountains primarily from the north vent starting on January 12 and reaching up to 800 feet (250 meters).

Episode 39 of the ongoing Halemaʻumaʻu eruption at the summit of Kīlauea volcano began on December 23, 2025, at approximately 8:20 p.m. and ended abruptly at 2:13 a.m. HST on December 24, 2025, after about 6 hours of continuous fountaining. USGS photograph by Lis Gallant.

The lava fountains that erupted during episode 39 at the summit of Kīlauea were visible through the rain and mist around 10 p.m. HST on December 23. This episode was actively erupting for just about 6 hours from December 23-24, 2025. USGS photo.

Kīlauea began its 39th lava fountaining episode the night of December 23, one year to the day from when this eruption began. This view was taken from the publicly accessible viewing area on Crater Rim Drive near Keanakākoi Overlook within Hawaiʻi Volcanoes National Park.

Photo compilation of the 38 lava fountaining episodes that occurred the first year of the ongoing eruption at the summit of Kīlauea. The eruption started on December 23, 2024, and the eruption continues: episode 39 is expected soon.

This map shows thickness values for lava flows within Halema‘uma‘u crater from the Kīlauea summit eruption that began on December 23, 2024. These values were calculated by topographic differencing between a digital elevation model collected on December 9, 2025—after eruptive episode 38—and one from before the eruption began.

It's been one year since a unique episodic lava fountaining eruption began at Kīlauea’s summit on December 23, 2024—a style of activity not seen in nearly 40 years! Over the past 12 months, Halemaʻumaʻu crater has hosted 38 eruptive episodes, each lasting from a few hours to more than a week, separated by quiet pauses.

Aerial photo showing the tephra hill on the western margin of Kaluapele (Kīlauea caldera), which has grown over the past year of 38 lava fountaining episodes within Halema‘uma‘u. The arcuate scarps are from landslides of tephra that have fallen back into the caldera near the north and south vents that have erupted all the material making up the tephra hill.

USGS staff deployed a new V3cam on the south rim of Halemaʻumaʻu crater at the summit of Kīlauea volcano, within Hawaiʻi Volcanoes National Park. The camera, a pan-tilt-zoom model, replaces the V3cam that was located to the west, which was destroyed during episode 38 lava fountaining on December 6, 2025. USGS photo by M. Patrick.

Aerial photograph looking at the southwestern rim of Kaluapele (Kīlauea caldera), where the original V3 livestream camera was located. This camera was buried under about 10 meters (32 feet) of molten spatter and tephra during inclined lava fountains of episode 38 on December 6, 2025. The upper third of the cliff face is this new spatter deposited during episode 38.

On December 9, USGS-Hawaiian Volcano Observatory geologists conducted an aerial overflight of Kīlauea summit region, following lava fountaining episode 38 of the Halemaʻumaʻu eruption on December 6. In this photo, the line on the ground in the lower left portion of the image shows the extent of tephra deposits created during episode 38.
