February 11, 2025 — Video of the north vent just prior to the start of episode 9

USGS Hawaiian Volcano Observatory geologists visited the Kīlauea eruption site at Haleaʻumaʻu the morning of February 11, 2025, just prior to the start of episode 9 of the eruption. From the caldera rim, they captured this video of the north vent, where the occasional spattering over the day prior had constructed a small cone within the vent. Episode 9 fountains reached up to around 330 feet (100 meters), perhaps in part due to the small cone creating a nozzle effect.
