May 5, 2025 — Telephoto view of south vent at Kīlauea volcano

This view of the south vent within Halemaʻumaʻu crater at the summit of Kīlauea was captured through the lens of a laser rangefinder device that Hawaiian Volcano Observatory scientists were using to measure eruptive features. The south vent was not as vigorously active as the north vent during the scientists' visit, with lava spatter being thrown only about 3 meters (10 feet) in the air. USGS photo by M. Zoeller.
