July 20, 2025 — Telephoto view of episode 29 at Kīlauea's summit

This view of episode 29 lava fountains within Halema‘uma‘u crater at the summit of Kīlauea was captured through the lens of a laser rangefinder device that USGS Hawaiian Volcano Observatory scientists were using to measure eruptive features. This photo was taken at 7:10 a.m. H.S.T. on July 20, 2025, nearly 2 hours after the start of episode 29. The north vent is at the center of the photo, and is noticeable wider than recent episodes. For scale, the prominent mound in front of north vent is approximately 27 meters (89 feet) high. The south vent was active for about 6 of the 13 hours of episode 29, and is seen here left (south) of north vent exhibiting low level fountaining. USGS photo by N. Deligne.
