Yellowstone is the crown jewel of the United States national park system. Its mountain vistas, wildlife and geographic features are visited and admired by people from around the world. More than any of those, however, it’s the park’s thermo-geological features that make it unlike any other part of the globe. No place on earth has as many steam vents, hot springs and active geysers as Yellowstone.
To create these features requires two elements in abundance: lots of water and lots of heat. The water is provided by the generous rain and snow the region gets. The heat comes from deep inside the earth: volcanic heat. Though you might not be able to tell from just looking at it, Yellowstone National Park is built on an ancient volcano. Not just a regular volcano, either. It lays on top of what some people have started to call a “super volcano.”
Oh Oh.
Scientists eye unusual swarm of Yellowstone quakes
Yellowstone National Park was jostled by a host of small earthquakes for a third straight day Monday, and scientists watched closely to see whether the more than 250 tremors were a sign of something bigger to come. Swarms of small earthquakes happen frequently in Yellowstone, but it’s very unusual for so many earthquakes to happen over several days, said Robert Smith, a professor of geophysics at the University of Utah.
“They’re certainly not normal,” Smith said. “We haven’t had earthquakes in this energy or extent in many years.”
