Video shared by the US Geological Survey on social media shows mud spraying up and out from the Black Diamond Pool in Yellowstone national park. Other recent eruptions have mostly been audible but not visible because they happened either at night or when the camera was obscured by ice. The agency said the Black Diamond Pool was previously the site of a hydrothermal explosion, in July 2024, that sent rocks and mud flying hundreds of feet into the air and damaged a boardwalk. It prompted the closure of the area to visitors due to the damage and potential for additional hazardous activity
