April 20, 2025 — Intermittent, minor vent activity at Kīlauea

Minor vent activity the morning of April 20 around 8 a.m. HST produced a small flow on Halema‘uma‘u crater floor and an intermittent dome fountain. The low fountain and spattering at the vent often showed a cycle of 3-4 minutes, with lava rising and falling in the conduit at that timescale. The activity was off and on into the early afternoon.
