Something changed at Yellowstone’s Biscuit Basin.
On June 13, 2026, USGS/Yellowstone Volcano Observatory reported a small hydrothermal explosion near Black Diamond Pool. This was not a lava eruption and not a volcanic eruption, but a steam-driven hydrothermal event where superheated underground water forced its way to the surface.
What makes this event important is what happened afterward: scientists found three new vent groups, a 61-foot fissure, near-boiling water around 89–90°C, and a brand-new boiling pool that later began spouting 20–30 feet high. The Firehole River also turned gray and milky from sediment released by the event.
Even though the Yellowstone volcano alert level remains NORMAL and the aviation code remains GREEN, this event is scientifically important because it happened close to new monitoring equipment installed after the 2024 Biscuit Basin explosion. That means scientists may now have rare camera, seismic, infrasound, and temperature data from one of Yellowstone’s most hazardous thermal areas.
In this video, I break down what happened, where the new vents opened, why Black Diamond Pool matters, how this compares to the 2024 explosion, and why hydrothermal explosions are one of the real hazards visitors should understand at Yellowstone.
This is Ray’s Astrophotography — where we investigate Earth, space, volcanoes, asteroids, fireballs, and the strange changes happening around our planet.
