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).

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 video, the line on the ground in the lower left portion at the start of the video shows the extent of tephra deposits created during episode 38.

The V3 camera was located on the south rim of Halema‘uma‘u crater at the summit of Kīlauea volcano on the Island of Hawai‘i. The camera, located in a hazardous closed area of Hawai‘i Volcanoes National Park, was buried by tephra from an inclined lava fountain between 9:55 and 9:57 am HST on December 6, during episode 38 that began this morning at 8:45 am.

During a USGS Hawaiian Volcano Observatory monitoring overflight the morning of December 2, 2025, geologists were able to see a spattering lava surface deep within the north vent. The yellow material around the vents is native sulfur.

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.

Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
