These thermal maps show the changing activity this week at Kīlauea summit. They were created from handheld thermal camera imagery collected during helicopter overflights yesterday and today. The February 3 map shows warm but inactive lava flows covering the crater floor, with several hot cracks cutting across the floor. Only weak spattering was present in the vent, with active lava flows. The February 4 map shows vigorous lava fountaining at the vent that was producing lava flows covering much of the western crater floor. Portions of the lava flow were ponded, with narrow channels draining the ponds.
