January 28, 2025 — Kīlauea Halema‘uma‘u eruption

Overview photo of episode 7 from the Kīlauea Halema‘uma‘u eruption. This photo was taken the morning of January 28, 2025, during a USGS Hawaiian Volcano Observatory morning monitoring field shift. Both vents (north and south) were active during this episode, with fountains and lava flows. Lava flows generally exit the cone from its base and flow into the caldera; however, lava flows exited the sides of the vents as well during episode 7. Lava flowed from the base of the north vent as well as out the side, where it flowed toward the south vent. The north vent had fountains reaching 45 m (145 ft) while the south vent had fountains reaching about 30 m (98 ft). Wind speeds were mild during the morning of January 28, allowing the eruptive plume to buoyantly rise up. This photo is looking northeast. USGS photo by H. Winslow.
