August 6, 2025 — Thermal map of Kīlauea episode 30 lava flows

The August 6 thermal map shows the widespread channelized lava flows covering the crater floor, originating from the episode 30 lava fountaining in the western end of Halema‘uma‘u crater at the summit of Kīlauea. Most of the lava originated from the vigorous fountaining at the north vent, with the weak fountaining at the south vent contributing a smaller volume. Also shown are two thermal maps collected during the quiet interval between lava fountaining episodes, when the crater floor consists of solidified, inactive lava.
