September 15, 2023 — Kīlauea summit eruption slowing

Detailed Description

During the morning of September 16, HVO field crews reported that active lava was no longer flowing onto Halemaʻumaʻu crater floor and was restricted to a ponded area north of the vents on the downdropped block in Kīlauea summit caldera. They observed lava spattering at the vents cease at approximately 11:15 September 16, and webcam views show the ponded lava stagnant by around noon. USGS photo by M. Patrick.
