This thermal map was taken on the 7 a.m. overflight of Kīlauea summit on April 9, 2025, and shows the expansive lava flow covering the floor of Halema‘uma‘u, supplied by lava fountains at the vent. As in earlier episodes, the lava exited the vent into a short channel that fed a broad perched lava pond. Lava channels then drained this pond and carried lava farther to the east. A small ooze-out, fed by lava supplied beneath the solidified crater floor, was present in the south portion of the crater. The fountaining ended a few hours after the flight, ending episode 17.
