A misty view across Kaluapele, Kīlauea summit caldera, on March 25, 2026, from the caldera rim near the Volcano House Hotel in Hawaiʻi Volcanoes National Park. The active north and south vents, on the southwest side of the caldera, are visibly degassing in this photo, following episode 43 of lava fountaining on March 10, 2026. The profile of the tephra mound that has grown throughout this eruption is visible on the rim of Halemaʻumaʻu crater, as well as Mauna Loa to left in the background. USGS photo by K. Mulliken.
