This timelapse sequence shows 3.5 hours of activity at the water lake in Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Several influx zones supply groundwater into the lake from the margins, creating shifting color zones on the lake surface. No significant changes have been observed in recent lake activity.
