The west vent and lava lake during a pause in Halema‘uma‘u activity
An aerial view of the western portion of Halema‘uma‘u, at Kīlauea summit, during the December 21 helicopter overflight. Eruptive activity is paused, and only a weak gas plume was being emitted from the west vent (center right). Just north of (below) the west vent, a tiny pad of lava remained weakly active within the lake. USGS photo taken by D. Downs.
