May 22, 2026 — View of altered Halemaʻumaʻu crater wall at Kīlauea summit
Detailed Description
A view of Halemaʻumaʻu crater wall near the south sulphur bank area, where the basalt has been altered and weathered by long-term degassing in this area, causing the pastel colors of discoloration. Lava flows from the 2024-ongoing lava fountaining eruption in Halemaʻumaʻu are visible in the foreground and have been slowly filling in the crater, covering Halemaʻumaʻu crater wall incrementally over time.
