March 10, 2026 — Tephra on a building in Hawai‘i Volcanoes National Park

This building within Hawai‘i Volcanoes National park is nearly 3 miles (4.7 km) east-northeast of north and south vents of the ongoing eruption of Kīlauea volcano. Tephra from episode 41 and 43 lava fountains of the ongoing Kīlauea eruption was deposited on this building. The upper portion of the roof is steeper and so falling tephra slide down it. The lower part of the roof has a shallow enough slope to accumulate tephra. This photo was taken nearly 4 hours after the start of episode 43, but the tephra on the lower part of the roof is from both episodes 41 and 43. The tephra on the ground is almost entirely all from episode 43. USGS photo by N. Deligne.
