April 2, 2025 — Growing tephra deposit at Kīlauea's summit
Detailed Description
During each eruptive episode in Halemaʻumaʻu, tephra is deposited on the crater rim downwind within the closed area of Hawaiʻi Volcanoes National Park. This sign for the Southwest Rift Zone of Kīlauea, which used to stand at least 6 feet (2 meters) above the ground surface, provides a visual for how thick the tephra deposit is at this location.
