The eruption occurred at around 10 a.m. local time at the park’s Biscuit Basin, according to the National Park Service. Various videos on social media show people were nearby when the explosion occurred, but there are no reports of any injuries.Â
According to the USGS, the Biscuit Basin parking lot and boardwalks are now temporarily closed for visitor safety. Â They noted that geologists are investigating the event.Â
Hydrothermal explosions occur when water suddenly flashes to steam underground, and they are relatively common in Yellowstone, USGS officials said.Â
