This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.
