May 11, 2025 — Episode 21 north vent lava fountain and plume at Kīlauea volcano

Kīlauea volcano's episode 21 occurred on May 11, 2025. This photo was taken a little more than an hour after lava fountaining started, and shows the north vent lava fountain with a volcanic gas plume rising above it. The height from the crater floor to the top of the cliff behind the fountain is approximately 540 feet (165 meters). From this perspective, lava flows from north vent have a silver appearance and are spreading east (left) across the crater floor. USGS photo by N. Deligne.
