March 21, 2025 — Kīlauea incandescence

The vent craters within Halema‘uma‘u were mostly obscured by the thick degassing plume the morning of March 21, but there were fleeting views of incandescence in the north crater. This photo shows what appeared to be a small collapse of the crater walls exposing hot material deposited from yesterday's fountaining, as opposed to fresh lava in the crater. A small amount of incandescence could be seen within the conduit, but it was unclear how active this surface was. USGS photo by N. Deligne.
