Summary
June 13 activity at Yellowstone's Biscuit Basin opened new vents and created a gray, vigorously boiling pool after a small hydrothermal explosion, with no injuries reported.
USGS said hydrothermal water surged through three newly formed vents near Black Diamond Pool, then flashed to steam and triggered the blast; water measured 185F to 200F.
One crack stretched about 61 feet and another 49 feet, while June 18 camera footage showed intermittent spouting from the new pool reaching 20 to 30 feet.
Biscuit Basin stayed closed because of the July 2024 Black Diamond Pool explosion, which meant no visitors were affected this time.
USGS has installed temporary seismic stations in the basin, underscoring the continuing hazard and instability of Yellowstone's hydrothermal system.
