On November 24, a USGS Hawaiian Volcano Observatory helicopter overflight was able to land on the floor of Halema‘uma‘u crater for scientists to collect a sample of cooled lava from a recent overflow of the Kīlauea summit eruptive vents.

A telephoto aerial view looking down into the north vent (center) of the ongoing Kīlauea summit eruption within Halema‘uma‘u crater. Orange incandescent lava is visible deep in the vent. Lava overflows from both vents over the past few days produced shiny new Pāhoehoe flows (bottom center and left side of photo).

With permission from Hawai‘i Volcanoes National Park, USGS Hawaiian Volcano Observatory scientists landed briefly on the floor of Halema‘uma‘u crater on November 21 to collect lava samples from Kīlauea summit eruption episodes 34, 35, and 36.

On November 21, USGS Hawaiian Volcano Observatory scientists collected solid lava samples from the floor of Halema‘uma‘u crater at the summit of Kīlauea. All sampling in this area, which is significant to native Hawaiian communities, is done with permission from Hawai‘i Volcanoes National Park.

On November 21, USGS Hawaiian Volcano Observatory scientists conducted an aerial overflight of the eruptive vent complex at the summit of Kīlauea. Roiling lava ponds were visible in both the north and south vents during the overflight; the north vent's incandescent pond barely visible in this aerial photo looking down from the north.

This photo, taken on November 18 from the south rim of Halemaʻumaʻu crater, shows slumping of material from the hill formed by fallout from the recent lava fountains at Kīlauea summit. The v3cam livestream camera is visible on the rim of the crater in the middle left of the image. USGS photo by M. Patrick.

This plastic road marker shown on the left side of this photo was found on the side of Crater Rim Drive within the hazardous closed area of Hawai‘i Volcanoes National Park, downwind of the episodically erupting vents within Halema‘uma‘u crater.

The west portion of Crater Rim Drive in Hawaiʻi Volcanoes National Park was damaged during the Kīlauea summit collapse of 2018. This area has remained closed to the public, being impacted by tephrafall and volcanic gas during recent eruptions. U.S.

Lava fountains from 36 episodes of the ongoing eruption in Halemaʻumaʻu crater, at the summit of Kīlauea, have built a prominent new puʻu (made up of tephra) perched on the rim of the crater. In the foreground, tephra covers part of Crater Rim Drive in this closed area of Hawaiʻi Volcanoes National Park. USGS photo by N. Kohagura. 

This wooden post used to mark the side of Crater Rim Drive within a hazardous closed area of Hawai‘i Volcanoes National Park. The post has been slowly buried by tephra from lava fountains that have been episodically active during the ongoing eruption of Kīlauea at Halema‘uma‘u that started on December 23, 2025.

This station has been buried incrementally by tephra as a result of lava fountaining, and solar panels were damaged by tephra impact. USGS photo by N. Kohagura.

Photo compilation of episodes 1–36 of the ongoing eruption at the summit of Kīlauea, including webcam imagery and photos taken by USGS Hawaiian Volcano Observatory scientists on the ground and during helicopter overflights. In all photos except for episode 7, the south vent is on the left and the north vent is on the right.

Episode 36 lava fountaining from Kīlauea's ongoing summit eruption formed tephra, including Pele's hair (strands of fine volcanic glass). Winds blowing from the north resulted in Pele's hair being deposited in Pāhala, a town about 20 miles (32 km) to the southwest of the eruptive vents in Halema‘uma‘u.

During the lava fountains of episode 33 on September 19, tephra particles traveled through the air and fell downwind west of Halema‘uma‘u. This clast was about 16 inches (40 centimeters) long, very lightweight due to being very bubble-rich, and delicate. USGS photo by N. Deligne.

The day after episode 36 of the ongoing Kīlauea eruption, USGS geologists inspected the tephra deposit west of Halema‘uma‘u, in the closed area of Hawai‘i Volcanoes National Park. This photo looks south, with Halema‘uma‘u out of view to the left.

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 section of Crater Rim Drive within Hawai‘i Volcanoes National Park was damaged in the 2018 summit collapse, and remains closed to the public. USGS photo by M. Patrick on November 9.
