Hydrothermal explosions occur when water suddenly flashes to steam underground, and are relatively common in Yellowstone. The boardwalk was damaged, but there were no reports of injury, according to a statement from the U.S. Geological Survey. https://abcnews.visitlink.me/BoAKzh | ABC News | Facebook
