Aerial view of Mauna Loa summit with Lua Hou in the foreground followed by Lua Hohonu, South Pit, and Mokuʻāweoweo summit caldera. A small dusting of snow covers the ground east of the summit. The steaming fissure was active during the beginning of the eruption, but this morning the lava in the summit caldera had already cooled to a black color.

November 1, 2021 — Kīlauea summit eruption
Eruptive activity continues in Halema‘uma‘u, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake. The base level of the pond fluctuates over the timespan of minutes.

Eruptive activity in Halema‘uma‘u crater—October 12, 2021
Eruptive activity continues at the west vent in Halema‘uma‘u crater, at the summit of Kīlauea. When this video was taken on October 12, a small subordinate vent was present on the north side of the main fountaining vent. The main fountaining source was supplying lava into the lake via a short spillway.
