April 29, 2025 — View of Kīlauea Iki and Pu‘upua‘i

This photograph, taken during a USGS Hawaiian Volcano Observatory monitoring helicopter overflight midday on April 29, 2025, shows an overview of Kīlauea Iki (center) and Pu‘upua‘i (bottom center to right). Kīlauea Iki erupted in 1959 over a 5-week period with 17 fountaining episodes, similar to the ongoing eruption in Halema‘uma‘u. Pu‘upua‘i formed as a result of the Kīlauea Iki lava fountaining activity, during which the highest lava fountains were recorded at Kīlauea, reaching up to 1,900 feet (580 meters) high. The pale line that cuts across Kīlauea Iki is the popular Kīlauea Iki trail. The ongoing eruption at Kīlauea's summit has now lasted over 4 months with episode 18 ending on April 22. USGS photo by N.
