West vent fountain sequence, Halema‘uma‘u, Kīlauea summit—Nov. 1, 2021
A sequence of telephoto images of the west vent (spanning 4 seconds), within Halema‘uma‘u at Kīlauea summit. The west vent continues to produce low-level lava fountains (seen here), which are forming an elevated pond of lava within the spatter cone. The pond then supplies lava to the lava lake through a small spillway that is obscured here by the volcanic gas plume. USGS photos taken on November 1, 2021, by N. Deligne.
