Yellowstone Volcano Observatory scientists recorded an explosion at Biscuit Basin, Yellowstone National Park on June 13, 2026 at 5:09 a.m. MDT.
The blast created three vents, including an 18.5-meter fissure of boiling water that threw rocks a few meters.
Water and sediment discharge turned the Firehole River milky, which preceded a collapse spouting 6-to-9-meter geyser-like jets by June 18.
YVO added cameras, seismic stations and monitoring gear while Biscuit Basin stays closed to visitors.
