West vent in Halema‘uma‘u, Kīlauea summit eruption—Oct. 15 2021

Detailed Description

A telephoto view of the west vent supplying lava to the lava lake in Halema‘uma‘u, at Kīlauea summit. In the bottom right, the western fissure complex from the Dec. 2020–May 2021 eruption is visible as a spiny dull dark brown and red feature. The old fissure has been lifted up by the current lava lake, and appears to be floating on the surface (similar to how an iceberg floats in the ocean). This photo was taken during a Hawaiian Volcano Observatory helicopter overflight on October 15 2021. USGS photo by N. Deligne.
