Photo and Video Chronology – Kīlauea – November 1, 2021

Release Date:

The ongoing eruption at Kīlauea's summit began at 3:21 p.m. HST on September 29, 2021. Lava activity is currently confined within Halema'uma'u crater. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

Kīlauea summit—October 29, 2021

Wide view of a lava lake, with the active lava lake and vent on the left and the dark solidified surface on the right

A wide view of the lava lake in Halema‘uma‘u, at the summit of Kīlauea, on October 29, 2021. This view, looking north, shows the west vent (left) which continues to supply lava to the active portion of the lava lake, while the eastern (right) portion is crusted over. The active lake is primarily between the west vent source and the main island (center). USGS photo by N. Deligne.

View of the west vent within Halema‘uma‘u, at the summit of Kīlauea, as seen from the western crater rim. Ponded lava within the west vent cone continues to flow down a spillway and into the lava lake. USGS photo taken on October 29, 2021, by N. Deligne.

Telephoto view of dark stagnant lava lake margin with active lava oozing between the edge and the rocky crater wall

A telephoto image of the southeast margin of the lava lake within Halema‘uma‘u, at Kīlauea summit. Although surface activity is confined to the western half of the lava lake and a narrow arm along the southern margin, the entire lava lake surface is continuing to rise. As the lake surface rises, the area of the lake increases, and lava squeezes up in the gap between the cooled crust and the crater wall. This photo was taken from the southern crater rim, in an area of Hawai‘i Volcanoes National Park that remains closed to the public due to safety concerns. USGS photo by N. Deligne.
