View of Halema‘uma‘u lava lake from the west, February 24, 2021

On Wednesday, February 24, HVO scientists observed the Kīlauea summit eruption in Halema‘uma‘u from the west rim of the crater. In this photo, the active western fissure is marked by an incandescent skylight on the near side of the lava lake. A plume of sulfur dioxide and other volcanic gases rises constantly from the fissure as it effuses lava into the lake, which measures approximately 900 m (3000 ft) from end-to-end at this time.
