Yellowstone Situation Just Got Even Worse - ANOTHER EXPLOSION?!

The pool at Biscuit Basin went off three times in five days. On September 23, Black Diamond Pool, the one that showered a boardwalk full of tourists with boulders in 2024, threw water and mud tens of feet into the air. On September 24 the new pool beside it, which did not exist in May, began erupting. And on the night of September 27, just after 8:12 PM, that new pool blew itself apart and threw boiling water, steam, mud and rock at least 100 feet into the sky. This time the instruments were watching: the U.S. Geological Survey says the explosion was "very well recorded by seismic, acoustic, and camera monitoring stations." And the same week, a 1926 ranger's letter revealed an explosion at the same basin in 1925 that nobody saw. Four explosions on record. Three in 26 months. Has it exploded again since? Here is the straight answer, and why it is not the comforting one. IN THIS VIDEO • Has Yellowstone exploded again since September 27?

The U.S. Geological Survey reports no sign of an approaching volcanic eruption. Hydrothermal explosions are a separate hazard and can occur without warning. As of October 8, 2026, no hydrothermal explosion has been reported in Yellowstone since September 27. Biscuit Basin has been closed to visitors since July 2024. #Yellowstone #YellowstoneVolcano #BiscuitBasin #HydrothermalExplosion #USGS #Supervolcano #NorrisGeyserBasin #Wyoming #NationalParks #CrisisRadar
