Geyser explosion sends park visitors fleeing at Yellowstone
A violent hydrothermal explosion at Yellowstone National Park sent visitors fleeing Tuesday as mud and debris erupted from a geyser just north of Old Faithful, according to park rangers. Video of the explosion showed a column of steam and dark earth launching high into the sky. “Run, run, run, run …” a woman shouted as parkgoers began running along a wooden boardwalk. The explosion occurred around 10:19 a.m. near Sapphire Pool in Biscuit Basin, just north of the Old Faithful geyser, the park service said in a news release. No injuries have been reported, but the event is still under investigation. Hydrothermal explosions occur when “water suddenly flashes to steam underground,” according to a statement from the U.S. Geological Survey. The agency said such explosions are “relatively common” at the park.
