Hydrothermal Explosion Rocks Yellowstone National Park, No Injuries Reported

A hydrothermal explosion occurred Tuesday morning at Yellowstone National Park, sending rocks and steam into the air near the Old Faithful geyser. The incident took place around 10:19 a.m. in Biscuit Basin, approximately two miles northwest of Old Faithful. Fortunately, there were no reported injuries, but the explosion damaged a nearby pedestrian boardwalk, prompting park officials to close the area for safety reasons. Witnesses captured the dramatic eruption on video, showing a column of black and gray material shooting into the sky as visitors, including children, fled the scene. The U.S. Geological Survey (USGS) explained that such explosions are caused by hot water rapidly turning into steam due to a drop in pressure, resulting in the ejection of boiling water, steam, mud, and rock fragments. The USGS noted that hydrothermal explosions are relatively common in Yellowstone, with a similar event occurring in Norris Geyser Basin earlier this year. Photos released by the National Park Service revealed debris covering the boardwalk and surrounding areas. Officials emphasized that the explosion was not related to volcanic activity, which is often a concern in the park. Instead, it was attributed to changes within the hydrothermal system. Park staff and USGS personnel are actively monitoring the situation and will determine when it is safe for visitors to return to the affected area.
