August 8, 2025 — View of Kīlauea Iki

An aerial view of Kīlauea Iki and Pu‘u Pua‘i taken during a USGS Hawaiian Volcano Obsrvatory monitoring overflight of Kīlauea summit on August 8. Pu‘u Pua‘i, the large cinder cone in the lower right of the image, was formed by tephra deposits from lava fountains similar to those that have been occurring in the last thirty episodes of the 2024-2025 summit eruption at Kīlauea. During the 1959 Kīlauea Iki eruption, fountains reached heights of 580 meters (1,900 ft), while the ongoing eruption has reached heights of 380 m (1250 ft). The Pu‘u‘ō‘ō vent, which was active from 1983-2018 (far, background), is visible in the distance. USGS photo by M. Decker.
