USGS Hawaiian Volcano Observatory field crews observed weak spattering from the interior of the north vent at Halema‘uma‘u during a Kīlauea summit field shift on February 3, 2025.

During a monitoring overflight around 7:30 a.m. HST, USGS Hawaiian Volcano Observatory field crews observed that spatter had built up a small cone within the north vent of the 2024-2025 Kīlauea summit eruption cones. The vent was weakly spattering within the cone during the flight. USGS photo by K. Lynn.

Episode 8 of the ongoing Halemaʻumaʻu eruption at the summit of Kīlauea began last night, February 3, 2025, at 9:52 p.m. HST. This view, captured just after 10 p.m. HST by the S2cams shows vigorous fountaining feeding multiple lava flows. USGS photo.  

During a monitoring overflight on February 3, 2025, USGS Hawaiian Volcano Observatory crews had excellent views of Kīlauea's west crater walls, where tephra deposits have been exposed following the collapse of the summit in 2018. This image shows talus (rock debris from the crater walls) surrounding a triangle-shaped exposure of tephra that is many meters thick.

With quite clear conditions on the morning of February 3, 2025, USGS Hawaiian Volcano Observatory crews on a monitoring overflight of Kīlauea summit had excellent views of the snow-capped Mauna Kea (shown here) and Mauna Loa. Both mountain summits received snow during a winter storm that passed over the Island of Hawai‘i last week. USGS photo by K. Lynn.

During a helicopter overflight around 7:30 a.m. HST on February 3, 2025, USGS Hawaiian Volcano Observatory field crews observed weak spattering in the north vent of the 2024-2025 Kīlauea summit eruption.

January 2025 was the 16th annual Volcano Awareness Month on the Island of Hawai‘i. The USGS Hawaiian Volcano Observatory promoted the importance of understanding and respecting the volcanoes on which we live, in part through an art and poetry contest. Winners of the art contest are displayed here. 

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 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.
