Fountaining from the west vent in Halema‘uma‘u crater

On October 19, 2021, the west vent that feeds lava into the Halema‘uma‘u lava lake at the summit of Kīlauea continues to erupt with 9 m (30 ft) high fountains. Lava within the vent is ponded about 5 m (16 ft) above the lava lake and flows into the lake on through an opening in the cone. This photo was taken at 2 p.m. HST from the south rim of the crater.
