July 9, 2025 — Aerial view of lava fountaining at Kīlauea during episode 28

Aerial view taken during a USGS Hawaiian Volcano Observatory helicopter overflight, showing the lava fountain of episode 28 within the summit caldera (Kaluapele) of Kīlauea. These lava fountains reached a maximum of 1150 ft (350 meters) but were mostly lower than this height throughout the fountaining episode. The tephra and eruptive plume were blowing to the southwest with strong trade winds. At the time of the overflight, around 11 a.m. HST on July 9. lava flows had only advanced a little less than halfway across the crater floor. USGS photo by D. Downs.
