January 28, 2025 — Kīlauea south vent erupting during episode 7

View of the south vent erupting during episode 7 of the Kīlauea Halema‘uma‘u eruption. The south vent reactivated for episode 7 (January 27-28) though it was relatively inactive during the prior episode 6. The vent shows a fountain and lava flow channel originating from the base of the cone. Lava has pooled at its base and flows down to the caldera floor. Fountain heights for the south vent were about 30 m (98 ft) high at 7:40 a.m. HST on January 28, 2025. USGS photo by H. Winslow.
