Kīlauea summit eruption in Halema‘uma‘u crater - October 5, 2021

A view of the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, taken from the western crater rim looking east. The western vent (lower right) remains the dominant source of fountaining. One fountain remains active in the south portion of the lake (center right). The silver-grey lava comes from the western vent, and the dark black lava comes from the south fountain. USGS photo by N.
