View looking down the north vent, taken during a USGS Hawaiian Volcano Observatory monitoring overflight on June 30, 2026. Glow and flames have been intermittently seen since episode 50 of lava fountaining in Halema‘uma‘u ended on June 27, 2026, but no glow was observed from the north or south vents during the overflight. The gas plume was robust and obscured good views into the vent conduits. USGS photo by D. Downs.

The black lava flows are rubbly ʻaʻā lava flows and the shiny, gray, smooth lava flows are pāhoehoe. USGS photo by D. Downs.

The north and south vents have a robust plume coming from them with fresh black and gray lava flows covering much of Halema‘uma‘u crater floor. The Kīlauea and Uēkahuna overlooks are in the foreground. USGS photo by D. Downs.
