A public notice sent by the USGS said that at approximately 10 a.m., an explosion occurred at Biscuit Basin, which is 2.1 miles northwest of the Old Faithful geyser.
The explosion reportedly damaged the boardwalk and is said to have originated near Black Diamond Pool. There were no other damages or injuries reported from the explosion.
The USGS said hydrothermal explosions are caused by water that “suddenly flashes to steam underground,” and that these types of explosions are “relatively common in Yellowstone.”
According to the notice, the explosion “does not reflect activity within volcanic system, which remains at normal background levels of activity.” Hydrothermal explosions are not caused by magma rising and are not a precursor of volcanic eruptions.
