June 1, 2026 — Episode 48 lava fountain at dawn

This photo of the Halema‘uma‘u north vent lava fountain was captured shortly after sunrise on June 1, 2026, around the time that activity was peaking during Kīlauea summit eruption fountaining episode 48. Preliminary estimates indicate that the lava fountain reached at least 500 feet (150 meters) in height during the episode. Most tephra was falling within the crater and immediately adjacent on the rim, but some lighter particles were lofted higher and greater distances downwind. USGS photo by M. Zoeller.
