April 1, 2025 — View lava fountains above crater rim during episode 16 at Kīlauea's summit

On April 1, lava fountains from Kīlauea's ongoing summit eruption prevented geologists from accessing the rim of Halemaʻumaʻu crater within the closed portion of Hawaiʻi Volcanoes National Park. Instead, they hung back along the closed portion of Crater Rim Drive to collect samples of tephra that was intermittently blown in their direction. Here, a USGS Hawaiian Volcano Observatory geologist watches over the tephra fallout zone from the eruption, waiting for wind conditions to permit sample collection. USGS photo by M. Zoeller.
