As USGS Hawaiian Volcano Observatory traversed under the volcanic plume from Kīlauea summit where it was transported downwind into the Kaʻū Desert area of Hawaiʻi Volcanoes National Park, they captured this view of the Maunaiki  shield and Kaʻū Desert trail.

USGS Hawaiian Volcano Observatory scientists conducted a monitoring overflight of Kīlauea summit the morning of May 22, 2026. During the overflight, they collected imagery to create a three-dimensional model of the crater floor, thermal imagery to determine the extent of episode 47 lava flows, and traversed beneath the volcanic plume to measure emission rates.

During a monitoring overflight on May 22, 2026, USGS Hawaiian Volcano Observatory scientists captured this aerial view looking down into the south vent in Halemaʻumaʻu at the summit of Kīlauea. Magma was visible within both the south and north vents during the overflight; the north vent is visible degassing on the right side of this image.

Trade winds during a USGS Hawaiian Volcano Observatory monitoring overflight on May 22, 2026, transported the plume to the southwest, into the Kaʻū Desert and closed area of Hawaiʻi Volcanoes National Park.

Comparison of the 1983–1986 Puʻuʻōʻō eruption lava fountain heights (top) with those of the 2024–ongoing Halemaʻumaʻu eruption (bottom).

The area south of Halema‘uma‘u has many ground cracks, many associated with the 2018 Kīlauea summit collapse and others associated with more recent earthquakes and ground deformation. While tephra from the ongoing summit eruption has covered and obscured many ground cracks, the deposit itself in places has deep cracks.

This view is of the cone (pu‘u) that has formed in the predominant downwind direction (southwest) of the north and south vents during the ongoing eruption at Halema‘uma‘u at the summit of Kīlauea. This photo is east of the southwest corner of Halema‘uma‘u and is looking to the northwest.

This telephoto view looking northwest shows the south vent (center), with the north vent (right) just out of view, in Halema‘uma‘u crater at the summit of Kīlauea. In the leadup to episode 47, the south vent had about 75 overflows, but only the north vent produced lava fountaining during episode 47. Both vents are degassing in the photo.

Misty weather partially obscured views of episode 47 at the summit of Kīlauea on May 14, 2026. This photo was taken approximately 2 1/2 hours into the eruptive episode, which began at 3:27 p.m. HST. Only the north vent erupted a lava fountain, which fed channelized lava flows across the crater floor within Kaluapele. USGS photo by L. Forster.

The lava fountain erupting from the north vent during episode 47 on May 14, 2026, seen here, sent light tephra into public areas of Hawai‘i Volcanoes National Park and surrounding communities to the northeast. Tephra is a general term for any fragmental material ejected during a volcanic eruption. USGS photo by L. Gallant. 

The north vent (right in photo) in Halemaʻumaʻu erupted a lava fountain during episode 47 at the summit of Kīlauea on May 14, 2026. It reached a maximum height of around 650 feet (200 meters). The south vent (left in photo) had intermittent spattering during the first two hours of the episode. USGS photo by L. Forster.

The lava fountain erupted by the north vent during episode 47 on May 14, 2026, reached about 650 feet (200 m) in height. It fed lava flows that covered portions of the floor of Halemaʻumaʻu crater and the southwest side of Kaluapele, Kīlauea's summit caldera. USGS photo by L. Gallant. 

K2cam captured this view of the north vent lava fountain visible from Uēkahuna overlook in Hawaiʻi Volcanoes National Park during eruptive episode 47 at the summit of Kīlauea on May 14, 2026. Visitors line the rock wall at the overlook to see the fountain from the north vent in Halemaʻumaʻu crater in the distance. USGS webcam image.
