“Kablooey!”
That’s the word U.S. Geological Survey volcanic experts used to describe a muddy eruption at Black Diamond Pool in Yellowstone National Park on Saturday morning.
Video shared by the USGS on social media shows mud spraying up and out from the pool just before 9:23 a.m. in Biscuit Basin about midway between park favorites Old Faithful and Grand Prismatic.
Other recent eruptions have mostly been audible and 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 high and damaged a boardwalk. It prompted the closure of the area to visitors due to the damage and the potential for additional hazardous activity.
So-called dirty eruptions reaching up to 40 feet (about 12 meters) have occurred sporadically since then.
Researchers installed a new camera and a seismic and acoustic monitoring station this summer, and they say the instruments, along with temperature sensors maintained by the Yellowstone National Park Geology Program, can better detect and characterize the eruptions.
The Yellowstone Volcano Observatory webcam at Black Diamond Pool didn’t disappoint Saturday.
