November 10, 2025 — View of the growing tephra hill after episode 36 at Kīlauea

The day after episode 36 of the ongoing Kīlauea eruption, USGS geologists inspected the tephra deposit west of Halema‘uma‘u, in the closed area of Hawai‘i Volcanoes National Park. This photo looks south, with Halema‘uma‘u out of view to the left. Tephra from the lava fountains continues to accumulate and since December 2024 has built up a hill that is more than 140 ft (42 m) high, covering Crater Rim Drive. During episode 36, which lasted only five hours, the hill grew by an estimated 30 ft (9 m). USGS photo by N. Deligne.
