The small pond feeding the eruption to the north of the west vent

The small 20-meter (66 foot)-wide pond to the north of the west vent in Halema‘uma‘u crater. This pond feeds the active part of the lava lake at the summit of Kīlauea volcano via a small cascade of only a meter or two (several feet) down into the larger lava lake. This photo was taken around 9:30 a.m. on Tuesday, February 1, 2022, from the west rim of Halema‘uma‘u. USGS photo by D. Downs.
