September 15, 2023 — Kīlauea eruptive activity

Mid-day on September 15, 2023, the eruption at Kīlauea continued with fountaining activity localized to only two active vents (one of which is shown here with red spatter). In this image looking to the north (with the former Jaggar Museum building visible on the caldera rim), one now inactive vent was incandescent and covered in a white coating from the degassing. The texture of the cones and the image foreground reflect spatter and tephra deposits. HVO field crews were sampling the tephra from these now inactive fissures. USGS photo by K. Lynn.
