November 25, 2025—Video of Kīlauea summit eruption episode 37

Episode 37 of the Kīlauea summit eruption in Halemaʻumaʻu began November 25 at 2:30 p.m. with lava fountaining from the north vent.  A wide fountain developed, eventually reaching heights of 500-600 ft (150-180 meters), sending flows across a broad portion of the crater floor.  The south vent showed only weak spattering and persistent flaming through the event.  North vent lava fountaining had diminished slightly by 8 p.m., and eventually terminated at 11:39 p.m. No tephra fall was observed on nearby roads. Preliminary estimates suggest that approximately 6 million cubic meters (7.8 million cubic yards) of lava were erupted during episode 37, based on ground deformation data. USGS video by M. Patrick.
