March 6, 2025 — Thermal map of episode 12 at Kīlauea summit

These thermal maps of the summit caldera at Kīlauea show the activity at two stages of episode 12. On the morning of March 4, the vent activity was just beginning, with a very small flow near the vent in the west portion of the caldera. Small ooze-outs of residual lava were also active. By the next day, March 5, more vigorous activity was present, along with extensive channelized flows on the crater floor and more widespread ooze-outs.
