Around 11 a.m. HST on August 25, 2026, USGS Hawaiian Volcano Observatory field crews had an aerial view of a growing lava fountain at the summit of Kīlauea during the onset of episode 54.

The lava fountain erupting from the north vent in Halemaʻumaʻu at the summit of Kīlauea during episode 54 on August 25, 2026, generated a lava flow on the caldera-wall side of the vent complex. This lava flow skirted the northwest part of the caldera wall.

A USGS Hawaiian Volcano Observatory gas scientist collects FTIR (Fourier transform infrared spectrometer) data during lava fountaining episode 54 in Halemaʻumaʻu crater at the summit of Kīlauea. This data is used to measure the chemical composition of volcanic gas being emitted during eruptive episodes. USGS photo by C. Gansecki.

This wide-angle, panoramic photo from the northwest rim of Halemaʻumaʻu shows the outgassing plume from Kīlauea summit eruption episode 53 lofting vertically and then drifting west—towards the summit of Mauna Loa—on August 12, 2026. The sun was setting behind the plume, creating an orange tint in the early evening. USGS photo by M. Patrick.

The spatter-fed flow on the north side of the vent was intermittent during Kīlauea summit eruption episode 53 lava fountaining on August 12, 2026. Changes in the shape of the fountain and spatter fallout zone often restarted the flow down the steep slopes of the vent cone. USGS photo by M. Patrick.

As the sun set on August 12, USGS Hawaiian Volcano Observatory geologists had excellent views of Kīlauea summit eruption episode 53 lava fountaining in the clear weather. The fountain shape changed rapidly, often shutting off the spatter-fed flow on the north side of the vent (right side of photo). USGS photo by M. Patrick.

This wide-angle photo looks east over Kaluapele, the summit caldera of Kīlauea, during the USGS Hawaiian Volcano Observatory helicopter overflight on August 11. The Halema‘uma‘u eruptive vents are in the lower-right corner of the photo, with the volcanic gas plume carried southwest in the trade winds.

Only the north vent erupted a lava fountain during episode 52 at the summit of Kīlauea. The south vent did not erupt any lava during precursory activity or the eruptive episode, but it did emit flames at the end of the episode. The north vent lava fountain reached a peak height of approximately 500 feet (150 meters) around 9:00 p.m. HST on July 28, 2026.

Another view of the north vent lava fountain during episode 52 at the summit of Kīlauea on July 28, 2026. Precursory activity began from the north vent on the morning of July 28 with 6 overflows between 10:22 a.m. and 1:53 p.m. HST, the longest lasting over 30 minutes.

Episode 51 of lava fountaining in Halemaʻumaʻu at the summit of Kīlauea took place for about 8 hours on July 15, 2026. This timelapse video of the episode was taken by the V2cam, located on the easter rim of the crater in Hawaiʻi Volcanoes National Park. The camera is a pan-tilt-zoom model so the perspective changes several times during the timelapse video.
