April 22, 2025 — Kīlauea Episode 18 Lava Fountaining Video

This video shows a clip from a USGS Hawaiian Volcano Observatory monitoring helicopter overflight on Tuesday, April 22, when high fountaining was occurring from the south vent at the summit of Kīlauea during episode 18 of the ongoing eruption. Other clips show activity captured during a field visit to the south rim of the caldera. While the main fountain originated from the south vent, the north vent had low fountaining within a lava pond that had continuous overflows down the cone flank. USGS video by H. Winslow and M.
