Staff at the USGS Hawaiian Volcano Observatory made observations of lava fountaining during episode 12 of the eruption in Halemaʻumaʻu, at Kīlauea summit. Both the north and south vents were active during the evening of March 4, 2025, when these videos were taken.

The USGS Hawaiian Volcano Observatory conducted a monitoring helicopter overflight of the eruption in Halemaʻumaʻu, at Kīlauea summit, at 10 a.m. HST on March 5, 2025. Episode 12 of the eruption was still active at this point in time, though it ended later that morning at approximately 10:37 a.m. HST.

Only weak vent activity was observed on the USGS Hawaiian Volcano Observatory monitoring helicopter overflight of Kīlauea summit at 8 a.m. HST on March 4, 2025. Weak effusive activity continued throughout the day until around 2 p.m., when fountaining started with more vigor, producing a larger flow across the crater floor. 

Views of episode 10 of the Kīlauea summit eruption in Halema‘uma‘u during a sunrise field shift on February 20, 2025. HVO scientists measured fountain heights of about 45-50 m (148-164 feet) on average with frequent pulses reaching 60-65 meters (197-213 feet). Episode 10 started the evening of February 19, 2025, around 8:22 p.m.

USGS Hawaiian Volcano Observatory staff conducted a monitoring overflight of Kīlauea summit at 12:30 p.m. on February 12, 2025, following the end of episode 9 of the eruption in Halemaʻumaʻu. A patchwork of lava flows of difference colors and different ages cover the floor of Halema‘uma‘u, at the summit of Kīlauea.

This compilation of videos shows views of episode 9 lava fountaining in Halema‘uma‘u at the summit of Kīlauea the evening of February 11, 2025. Lava fountain heights were decreased from the morning of February 11, when episode 9 began. At approximately 8:15 p.m.

USGS Hawaiian Volcano Observatory geologists visited the Kīlauea eruption site at Haleaʻumaʻu the morning of February 11, 2025, just prior to the start of episode 9 of the eruption. From the caldera rim, they captured this video of the north vent, where the occasional spattering over the day prior had constructed a small cone within the vent.

This video compilation shows views of lava fountaining in Halema‘uma‘u at the summit of Kīlauea on February 4, 2025. Lava fountain heights reaching approximately 50 meters (yards). Fountaining occurs through pond which supplies lava through a narrow notch in the cone wall. 

During a helicopter overflight on Tuesday, February 4, USGS Hawaiian Volcano Observatory geologists landed on the floor of Halema‘uma‘u crater to collect lava samples from episode 8 of the ongoing Kīlauea summit eruption.

Episode 7 of the Halemaʻumaʻu eruption began at 6:42 p.m. HST on January 27, and continued through the night. Lava fountains fed a small flow onto the crater floor. This timelapse video is from the KWcam, which is located on the west caldera rim and looks east across Kaluapele (Kīlauea summit caldera) within Hawaiʻi Volcanoes National Park. 

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. This video compilation shows aerial views of Halema’uma’u captured during the overflight. 

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 high-resolution video of lava fountains at the northern eruptive vent (right) within Halema‘uma‘u crater.

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 video of spattering at the two active vents of the ongoing Kīlauea summit eruption.

Compilation of videos collected at approximately 10 a.m. HST on January 17, 2025, during a USGS Hawaiian Volcano Observatory monitoring overflight of the ongoing summit eruption within Halemaʻumaʻu at the summit of Kīlauea. Several aerial views show the two erupting vents located in the southwest part of the caldera.

Compilation of videos taken of the Kīlauea summit eruption in Halemaʻumaʻu on January 17, 2025. Several clips show lava fountaining at the vents located in the southwest part of Kaluapele (the summit caldera), as well as lava flowing out of the south vent. The last clip shows a wind vortex (lavanado) within the caldera.

This video, taken from the west rim of Kaluapele (Kīlauea caldera), in the closed area of Hawaiʻi Volcanoes National Park, shows the new eruption that started this morning at 2:20 a.m. HST. At approximately 4:30 a.m.

On September 19, 2024, USGS-Hawaiian Volcano Observatory geologists landed near the Kīlauea middle East Rift Zone eruption site, where they viewed lava flowing through a channel more than 50 meters (about 164 feet) wide. 

USGS Hawaiian Volcano Observatory field monitoring crews captured these videos during their visit to Kīlauea middle East Rift Zone eruption site the morning of September 20, 2024. They reported minor spattering and small fountains at one end of the vent at 8:30 a.m. HST. By 10 a.m.

On the night of September 15, USGS Hawaiian Volcano Observatory geophysical data indicated that an eruption could be occurring a remote area of Kīlauea’s middle East Rift Zone, within Hawaiʻi Volcanoes National Park.

USGS Hawaiian Volcano Observatory geologists conducted a reconnaissance overflight of the eruption near Nāpau Crater on the middle East Rift Zone of Kīlauea. They observed lava cascading over the rim of the crater from a channel more than 50 meters (about 164 feet) wide.
