July 29, 2026—Kīlauea Iki and East Rift Zone
During the USGS Hawaiian Volcano Observatory overflight on July 29, geologists had clear views to the east of Kīlauea summit—a somewhat rare occurrence, as this area is often cloaked in misty rain. Here, Kīlauea Iki is seen in the foreground, with the East Rift Zone stretching across the background.

July 29, 2026—Overview of Halema‘uma‘u
On July 29, clear skies provided USGS Hawaiian Volcano Observatory geologists with excellent views of Halema‘uma‘u during a morning helicopter overflight after Kīlauea summit eruption episode 52 ended overnight. In fact, the only cloud casting shadows over the crater was the residual gas plume from the eruptive vents, which was rising vertically due to calm winds.

July 29, 2026 — Thermal map of Kīlauea summit
This thermal map shows the summit of Kīlauea hours after the end of episode 52 lava fountaining on July 29, 2026. The lava flow produced by this fountain mainly flowed along the southern perimeter of the crater floor, and was stalled by the time of the overflight. However, several small breakouts were still active in several areas.

July 28, 2026 — Kīlauea summit eruption episode 52 at nightOnly 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.
