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.

An eruptive plume rises from the summit of Kīlauea volcano, visible from Highway 11 near Volcano Village on the Island of Hawaiʻi. This plume was generated during episode 38 of lava fountaining within Halemaʻumaʻu crater, which took place on December 6, 2025. USGS photo by K. Mulliken.

In the late morning of December 6, a crew of USGS Hawaiian Volcano Observatory scientists walked to the southern rim of Halemaʻumaʻu to watch Kīlauea summit eruption episode 38. Along the way they had dramatic views of the eruptive plume, which reached an altitude of over 20,000 feet (6,000 meters) above sea level during this episode. USGS photo by M.

A USGS Hawaiian Volcano Observatory field crew captured this photo of Kīlauea summit eruption episode 38 from the southern rim of Halemaʻumaʻu just after noon on December 6. This was shortly after the north vent shut down, so only south vent lava fountains were ongoing, measured to reach 920 feet (280 meters) in height at the time. USGS photo by M.

The steaming north wall of Halemaʻumaʻu crater wall rises several hundred feet above the lava flows that cover the floor of the crater.

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.

This aerial photograph, taken during a USGS Hawaiian Volcano Observatory monitoring overflight the morning of December 2, 2025, shows volcanic gas wafting over the tephra-blanketed rim of Halemaʻumaʻu crater. The ripple-like deposits on the right side of the image, on the crater rim, are spatter-fed lava flows that formed during episode 34 on October 1.

The north and south vents were degassing during a USGS Hawaiian Volcano Observatory monitoring overflight of Kīlauea summit on December 2, 2025. Eruptive activity at these vents was paused on December 2, following 9 hours of lava fountaining during episode 37 on November 25, but a spattering lava surface was visible deep within both vents.

The USGS Hawaiian Volcano Observatory often gets asked how long it will take the lava flows to fill in Halemaʻumaʻu crater and spill onto the upper caldera floor of Kīlauea. This photo, taken from the floor of the crater, shows the lava flows from episode 37 (November 25) where they contact the north wall of the crater, which rises several hundred feet above.

Both vents were actively degassing, and a spattering lava surface was visible deep within their conduits.  USGS photo by D. Downs

This black solidified lava channel is a stark contrast to the weathered brown walls of Halemaʻumaʻu crater nearby. The lava channel transported lava from the north vent, along the north rim of the crater, allowing lava flows to reach the farthest regions of the crater to the east during the 9 hours of lava fountaining of episode 37 on November 25, 2025.

The left map shows the tephra fall associated with Kīlauea's episodic summit eruption, from December 2024-December 2025. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground.

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 November 24, 2025; as such, the provided statistics are reflective of the first thirty-six episodes of the eruption through November 9.
