March 20, 2025 — Timelapse video of episode 14 fountaining, Kīlauea

This timelapse video shows the full sequence of activity during episode 14 of the ongoing summit eruption of Kīlauea. The activity began with many hours of filling-draining cycles at both the north and south vents - these are periodic rise-and-fall cycles in the lava column that accompany low-level spattering and small overflows. Eventually, full fountaining began in the early morning hours of March 20, with fountain heights extending far above the crater rim - this indicates that fountain heights were approximately 200 meters (650 feet). In the early afternoon, fountaining abruptly ended, terminating episode 14.
