Kīlauea images of eruptive activity, field work, and more.
An aerial view of the December 31, 1974 fissures and lava flows taken during an overflight of Kīlauea summit and upper Southwest Rift Zone on March 14, 2025. The 1974 eruption lasted 6 hours and occurred in Kīlauea's upper Southwest Rift Zone.

Hawaiian Volcano Observatory geologists captured this aerial view of Kīlauea summit on March 14, 2025, during a helicopter overflight. Three days after the end of episode 13 of the ongoing eruption, the north and south cones are degassing in the southwest corner of Halema‘uma‘u.

On the morning of March 14, USGS Hawaiian Volcano Observatory scientists conducted an overflight of Kīlauea summit to capture thermal and surficial imagery of the ongoing (paused) eruption. Three days after the end of episode 13, this telephoto aerial view shows the north cone degassing in the southwest corner of Halema‘uma‘u.

On March 12, a USGS Hawaiian Volcano Observatory geologist on the southwest rim of Kaluapele (Kīlauea summit caldera) serviced the S2cam webcam. A plume of water vapor and volcanic gas rises from the two vents of the ongoing eruption within Halema‘uma‘u crater, one day after the 13th episode of the eruption. USGS photo by N. Deligne.

The section of Crater Rim Drive downwind of the recent fountaining, and in an area closed to the public due to volcanic hazards, has been covered by numerous layers of tephra in the past several months. The tire tracks are centered over the Crater Rim Drive roadway, where USGS scientists access critical volcano monitoring sites.

On the morning of March 11, the north vent was producing lava fountains about 50 meters (160 feet) high, with fountaining emerging from a small, sloshing pond held within the walls of the north vent cone. The pond can be seen in the lower left portion of the photo, as well as the lava spillway which exits through a notch in the cone that is obscured in this view.

An HVO geologist returns from a tephra collection bucket at the summit of Kīlauea, carrying a new sample. The outgassing plume from the vents is carried over the roadway, now covered by over 50 cm (20 inches) of tephra in places. All samples are collected in coordination with, and after receiving permission from, Hawai‘i Volcanoes National Park. USGS photo by M.

A USGS Hawaiian Volcano Observatory geologist uses a handheld laser rangefinder on the southwest rim of Kaluapele (Kīlauea summit caldera) to measure the height of the recently active cones within Halema‘uma‘u. USGS photo taken on March 12, 2025, by M. Patrick.

A closeup view of the south cone at the summit of Kīlauea, showing the semi-molten nature of the cone flanks. During fountaining, lava accumulates on the cone's flanks at such a high rate that the material remains hot and semi-molten, despite the appearance of cooled, solid material on the surface.

An orange five-gallon plastic bucket, secured by heavy weights, was one of several used to collect tephra from the ongoing lava fountaining at the summit of Kīlauea. The episode 13 fountaining, however, cast large bombs (some of them molten) in this particular area, battering the ground.

On March 11, HVO geologists observed episode 13 of the ongoing Kīlauea summit eruption from the western caldera rim. Lava fountains from the north vent (left) and south vent (right) were feeding channelized flows across the floor of Halema‘uma‘u crater. USGS photo by M. Patrick.

Episode 13 fountaining began early on March 11 and continued through an HVO helicopter overflight of the Kīlauea summit region around 10:00 a.m. Visibility was slightly hampered by passing showers.

During a March 11 Hawaiian Volcano Observatory eruption monitoring flight at Kīlauea summit, scientists landed to make observations and collect samples. At the front of the channelized flow from the episode 13 north vent fountain in Halema‘uma‘u crater, a USGS geologist walks the flow margin to find a safe spot to collect a molten lava sample.

In this image captured on USGS Hawaiian Volcano Observatory research camera S2cam, fountains erupt with similar heights from the north and south vents during episode 13 on March 11, 2025. The maximum fountain height during this episode was 215 meters (700 feet), measured at the north vent. USGS photo.

On the Halema‘uma‘u crater floor, the front of a fast-moving channelized lava flow from the north vent fountain was composed of slabby pāhoehoe. USGS photo taken on March 11, 2025, by M. Patrick.

A telephoto view of the northern vent fountain within Halema‘uma‘u crater. The steep septum separating the north and south fountains was under constant barrage today by molten lava falling from the fountains, with the steep walls on the inside of the cones in a state of constant dripping and flowing back into crater.

The closed portion of Crater Rim Drive, just west of the active vents, has been covered by a deep layer of tephra falling out downwind from the recent lava fountains. In this section, the deposit is only a few inches thick, but farther down the road the tephra has accumulated into drifts that are up to about a half meter (or half a yard) thick.

The north vent in Halema‘uma‘u crater was producing lava fountains about 160 feet (50 meters) high on the morning of March 11, with these fountains emerging from a small, sloshing pond inside the walls of the vent's spatter cone.

On March 10, 2025, field teams saw low-level spattering from a small opening within north cone, active during recent eruptive episodes of the ongoing eruption at Halema‘uma‘u, Kīlauea volcano. This indicates that magma is very close to the surface. This photo was taken at 1:32 p.m. H.S.T., looking down nearly 600 feet (183 meters) above the crater floor.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. As of this posting on March 10, the eruption has had twelve episodes, with a thirteenth likely to occur the next 24 hours.
