Halemaʻumaʻu west vent glow
Photo of the west vent within Halema‘uma‘u crater, which has been built up with spattering lava thrown out since the current Kīlauea summit eruption began in September 2021. In this photo, the west vent interior glows and is emitting a heavy sulfur dioxide-rich plume. Very little spatter was being thrown out of the west vent when this photo was taken at around 9:30 a.m. on Tuesday, February 1, 2022, from the west rim of Halema‘uma‘u. USGS photo by D. Downs.
