April 15, 2025 — Views into the eruptive vents at the summit of Kīlauea during a pause

A view of the north and south vents within Halemaʻumaʻu, Kīlauea volcano, on April 15, 2025, taken from the south rim of the caldera. USGS Hawaiian Volcano Observatory geologists measured the height of the crater wall behind the vents using a laser rangefinder. The distance between the lowest part in the center of the south vent and the lava flows at the lava flows at the top of the crater wall is approximately 150 meters (492 feet) on April 15, 2025. With every eruptive episode, this measurement changes as the cones around the vents grow with new material added to them.  USGS photo by K. Mulliken.
