USGS Hawaiian Volcano Observatory geologists observed episode 7 of the Kīlauea Halema‘uma‘u eruption on the morning of January 28, 2025. The eruption resumed in both the north and south vents with fissure fountains and outpouring of lava flows on the caldera floor.

Telephoto view of both eruptive vents in the Kīlauea Halema‘uma‘u eruption during episode 7 on January 28, 2025. Both vents reactivated during this episode. The north vent (upper left vent) fountain produced lava channels outpouring from its base but also out the sides of the vent as seen in this photo.

View of the south vent erupting during episode 7 of the Kīlauea Halema‘uma‘u eruption. The south vent reactivated for episode 7 (January 27-28) though it was relatively inactive during the prior episode 6. The vent shows a fountain and lava flow channel originating from the base of the cone. Lava has pooled at its base and flows down to the caldera floor.

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.

The north vent that was erupting during episode five of the recent Kīlauea summit eruption has a small patch of lava that was weakly spattering during the morning of January 24, 2025. USGS photo by J. Barnett.

Volcanic ash, tephra particles that are less than 2 mm in size (less than 0.08 in), collecting on a vehicle windshield and hood in Hawaiian Paradise Park during episode 41 lava fountaining at the summit of Kīlauea. This vehicle was parked approximately 25 miles (40 km) away from the eruptive vents.

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.

Aerial view of tephra erupted from December 23, 2024, to present (with several pauses) and deposited within the closed area of Hawai‘i Volcanoes National Park. Early in the eruption the lava fountains were ejecting bombs and lapilli across the closed portion of Crater Rim Drive. In places this tephra gets to almost a foot (30 cm) thick. USGS photo by D. Downs.

USGS Hawaiian Volcano Observatory scientists conducted a monitoring overflight of the ongoing summit within Halemaʻumaʻu at the summit of Kīlauea. This aerial view shows the two erupting vents that are located in the southwest part of the caldera. A portion of Crater Rim Drive that collapsed into the caldera in 2018 is visible in the foreground of the photo.

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.
