November 25, 2025—Kīlauea summit eruption episode 37 lava fountains

Following several days of precursory overflows and low dome fountaining, episode 37 of the Kīlauea summit eruption began yesterday 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 photo by M. Patrick.
