Overview photo of episode 7 from the Kīlauea Halema‘uma‘u eruption. This photo was taken the morning of January 28, 2025, during a USGS Hawaiian Volcano Observatory morning monitoring field shift. Both vents (north and south) were active during this episode, with fountains and lava flows.

Sunrise at the summit of Kīlauea this morning, January 28, 2025. Episode 7 of the ongoing Halemaʻumaʻu eruption began at 6:42 p.m. HST last night, January 27, and continued through the night. Lava fountains fed a small flow onto the crater floor.

USGS Hawaiian Volcano Observatory scientists landed east of the recently erupting vents at Kīlauea summit on January 24, 2025. They landed on a cooled part of Halema’uma’u crater floor and scouted for a good place to sample the most recently erupted flow. USGS photo by J. Barnett.

On the morning of January 24th, USGS Hawaiian Volcano Observatory scientists conducted an overflight of Kīlauea summit to capture thermal and surficial imagery of the December 2024 to January 2025 paused eruption.

During a USGS Hawaiian Volcano Observatory monitoring overflight the morning of January 24, 2025, geologists observed that parts of the recently erupted lava flows are already showing signs of alteration. Fumarolic areas where degassing has occurred are marked by white alteration that has developed on the lava flows that make up the floor of Halema‘uma‘u.

This telephoto view of the northern eruptive vent within Halema‘uma‘u crater at the summit of Kīlauea was captured through the lens of a laser rangefinder late in the afternoon on Wednesday, January 22, 2025. USGS Hawaiian Volcano Observatory geologists used the rangefinder to measure lava fountains consistently reaching 100 feet (30 meters) in height.

Kīlauea'S 2024-2025 eruption resumed around 3 pm HST on January 22, 2025, and ended around 4:30 am HST on January 23, 2025. USGS Hawaiian Volcano Observatory field crews observed the eruptive vents around 9 am on January 23 after the eruption had paused again.

In the early evening of Wednesday, January 22, just a few hours into the fifth episode of Kīlauea's summit eruption, USGS Hawaiian Volcano Observatory geologists captured this view of lava fountains at the northern eruptive vent (right) within Halema‘uma‘u crater. The southern eruptive vent (left) was degassing but not actively erupting at the time.

This panorama of Kīlauea summit eruption's fifth episode was captured by USGS Hawaiian Volcano Observatory geologists around sunset on Wednesday, January 22. A tripod camcorder on the crater rim in the foreground was used to record high-resolution video of lava fountains at the northern eruptive vent within Halema‘uma‘u crater. USGS photo by M. Zoeller.

View from the southwest rim of Kaluapele, the summit caldera of Kīlauea, where the temporary S2 webcam is located. This view looks down on the active north and south vents on the morning of January 17, 2025, as lava fountains reached 100-115 ft (30-35 m) high and feeding lava flows in the western part of Halemaʻumaʻu.

Close up view of the south vent from the southwest rim of Kaluapele, the summit caldera of Kīlauea, on the morning of January 17, 2025. The cone is almost 100 ft (30 m) high and the lava fountain is just as high to slightly high at times. The outlet at the front of the cone is feeding some of the lava flows in the western part of Halemaʻumaʻu. USGS photo by D.

Over the past day, persistent lava fountaining at Kīlauea summit, coupled with Kona wind conditions, has resulted in Pele's hair falling on nearby communities and within parts of Hawaiʻi Volcanoes National Park.

USGS Hawaiian Volcano Observatory scientists conducted a monitoring overflight of the ongoing summit within Halemaʻumaʻu at the summit of Kīlauea. This low-angle aerial view looking westward shows the two erupting vents that are located in the southwest part of the caldera, and along with the Pāhoehoe lava flowing out of the vents.

With permission from Hawaiʻi Volcanoes National Park, USGS Hawaiian Volcano Observatory scientists conducted Uncrewed Aerial Systems (UAS) operations at the Kīlauea summit eruption site on January 17, 2025. Scientists conducted flights to assess volcanic gas emissions and take aerial imagery, which will aid in hazard assessment of the ongoing eruption.

On Friday, January 17, USGS Hawaiian Volcano Observatory (HVO) geologists flew an uncrewed aircraft system (UAS, or "drone") into Halema‘uma‘u crater to capture this close-up photo of spattering at the two active vents of the ongoing Kīlauea summit eruption.
