A hydrothermal explosion occurred in Yellowstone National Park's Biscuit Basin on July 23, sending steam, boiling water, and debris hundreds of feet into the air, prompting visitors to flee for safety. The explosion, which destroyed a portion of a boardwalk and affected the Black Diamond and Black Opal Pools, was caused by a sudden transition of underground water to steam due to pressure changes. Although no injuries were reported, the area remains hazardous, with debris and unstable ground conditions persisting. The National Park Service has indicated that the Biscuit Basin will be closed for the rest of the year while monitoring continues, as small explosions could occur in the coming months. According to experts, this event does not signal an increased risk of volcanic activity in the park. Yellowstone, sitting atop a volcanic hotspot, has a history of such explosions, but this particular incident does not indicate an imminent super-eruption.
