This image, captured on November 9, 2025, by the USGS Hawaiian Volcano Observatory S2cam, shows lava fountaining from the north and south vents during episode 36 of ongoing eruption at the summit of Kīlauea. Episode 36 lava fountaining began at 11:15 a.m. on November 9 and was over just 5 hours later, at 4:16 p.m. that same day.

This image, captured by the USGS Hawaiian Volcano Observatory KWcam, shows lava fountains erupting during episode 35 of the Kīlauea summit eruption. Dual lava fountains within Halemaʻumaʻu crater feed lava flows on the crater floor. USGS webcam image taken on October 18, 2025. 

This image, captured by the USGS Hawaiian Volcano Observatory K2cam, shows lava fountains erupting during episode 34 of the Kīlauea summit eruption.

Just before dawn during episode 34 on October 1, 2025, the north and south vents both erupted, creating a spectacular column and sending lava flows over crater floor as viewed from USGS Hawaiian Volcano Observatory livestreaming V2cam. The north vent achieved a slightly higher fountain than the south at 383 meters (1256 feet).

The South Point repeater station, located near the southern point of the Island of Hawaiʻi, is an important data relay station. USGS photo. 

A USGS Hawaiian Volcano Observatory geologist surveys the elevation along a transect across the new tephra cone formed by the recent lava fountaining episodes at the summit of Kīlauea. Repeat measurements across the same set of points have been done after every episode starting with episode 23, to track the growth and changes of the tephra hill. USGS photo by M.

The tire tracks in this photo trace the path of Crater Rim Drive (closed to the public) in Hawai‘i Volcanoes National Park. This part of the road is covered by tephra erupted from Kīlauea volcano since December 23, 2024. Where the photo is taken the tephra is over 5 feet thick, increasing to over 60 feet thick at the mound of tephra on the skyline.

This panoramic image shows Halema‘uma‘u crater a few days after the end of episode 33 of the ongoing eruption of Kīlauea volcano. This photo, looking eastward (north is left, south is right), was taken from near the top of the mound of tephra that has accumulated west of Halema‘uma‘u since the start of the eruption in December 2024.

On September 24, 2025, a USGS Hawaiian Volcano Observatory scientist serviced a monitoring station at Kīlauea volcano. This site is only accessible by helicopter due to the 2018 summit caldera collapse—the road in the photo is an isolated portion of the old Crater Rim Drive, over 100 feet below the current crater rim.

This thermal map shows the temperature distribution on the crater floor at the summit of Kīlauea. The ongoing eruption has covered the crater floor in successive layers of new lava flows. This thermal map shows that the flows that erupted during episode 33 (September 19) remain warm, and are visible along the north and south margins of the crater.

On September 24, 2025, USGS Hawaiian Volcano Observatory field crews collected samples from a cooled 'a'ā lava flow erupted during episode 33 (left half of photo in foreground) at Kīlauea volcano. This was part of a morning monitoring helicopter overflight of Kīlauea summit.

USGS Hawaiian Volcano Observatory scientists took this oblique angle view of north (center) and south vents (to the right and closer to top of photo) during a Kīlauea summit monitoring overflight on September 24. The brown sand-like material that covers the right and top parts of the photo are tephra erupted during episode 33.

The USGS Hawaiian Volcano Observatory's helicopter overflight on September 24 provided aerial views of Kaluapele (Kīlauea caldera) from the east looking west. The vents of the eruption that started on December 23, 2024 are degassing on the western side of Halema‘uma‘u crater. Mauna Loa can be seen in the background. USGS photo by N. Deligne.

USGS Hawaiian Volcano Observatory scientists did not see any lava at the bottom of north (bottom right) or south (center) vents during a Kīlauea summit monitoring overflight on September 24. This photo shows the western wall of Halema‘uma‘u, and much of the slope is covered in brown tephra erupted during episode 33 on September 19. USGS photo by N.

This aerial view of Kīlauea Iki (center crater with lava covering the floor) and Pu‘u Pua‘i (brown hill to its right) was taken during a USGS Hawaiian Volcano Observatory monitoring overflight of Kīlauea summit on September 24. On the horizon from left to right are, Pu‘u‘ō‘ō (center), Kānenuiohamo (right of center), and Maunaulu (right).
